When to Call a Local HVAC Contractor: A Homeowner's Guide

Thu, 29 Jan 2026 16:23:44 GMT

Are you wondering when it’s time to call a local HVAC contractor in Indianapolis, IN? Whether you’ve just experienced a sudden chill or an unexpected heat wave, knowing when to reach out can save your home and your sanity. Preferred Mechanical Services understands how overwhelming HVAC issues can be, and this guide will walk you through the key signs that indicate you need professional help. From true emergencies like furnace failures in freezing weather to the dangers of DIY repairs on electrical or gas components, this article will help you recognize when 24/7 emergency HVAC service is truly necessary.

Understanding True HVAC Emergencies

When temperatures plunge during an Indianapolis winter or soar in the summer, your HVAC system becomes more than just a convenience; it’s a lifeline. Recognizing true HVAC emergencies is critical. For example, a complete furnace failure during a freeze can put you and your family at serious risk of hypothermia or carbon monoxide poisoning. Similarly, an air conditioner breakdown amid a heatwave can cause heat exhaustion or dehydration, especially for vulnerable family members such as children or the elderly.

If your heating or cooling system stops working altogether when you need it most, it’s time to contact a local HVAC contractor immediately. These situations demand prompt response, and the availability of 24/7 emergency HVAC service ensures that help is always available no matter the hour.

Why DIY Repairs Can Be Dangerous

It’s tempting to handle simple HVAC fixes yourself, especially when you see a quick leak or a strange noise. However, HVAC systems are complex, and DIY repairs can often make a bad situation worse. Attempting to repair gas lines can be extremely hazardous; improper handling can lead to leaks, explosions, or toxic exposure. Similarly, tampering with electrical components presents a significant risk of shock or fire.

When in doubt, your safest bet is to call a trusted local HVAC contractor in Indianapolis, IN. Professionals have the training, tools, and certifications to handle these repairs safely and efficiently. Relying on 24/7 emergency HVAC service in Indianapolis, IN, can prevent accidents and costly damage while ensuring your system is restored correctly the first time.

Signs You Should Call a Local HVAC Contractor

Knowing when small problems require professional attention can save time and money in the long run. Here are some warning signs that indicate you should call a local HVAC contractor in Indianapolis, IN:

No Heat or Cooling: If your furnace or air conditioning system fails to turn on or blows cold air in winter/summer.
Strange Noises: Banging, rattling, or grinding sounds can signal mechanical failure.
Foul Odors: Musty, burning, or gas-like smells often indicate dangerous issues.
High Energy Bills: A sudden spike in utility costs might mean your HVAC is running inefficiently.
Frequent Cycling: HVAC systems turning on and off rapidly can signal a malfunction.
Water Leaks: Any visible leaking water or moisture from units or ductwork is a red flag.

In any of these cases, contacting a local HVAC contractor can quickly diagnose and resolve the problem. And if you find yourself facing a true emergency, the availability of 24/7 emergency HVAC service in Indianapolis, IN, means you’re never left in the cold or the heat.

Easy Ways To Save on Air Conditioning Costs This Summer

Fri, 21 Jul 2023 17:39:00 GMT

The hot summer temperatures can make your home uncomfortable. However, if your air conditioning works too hard, it can significantly increase your energy bills. Here are tips to reduce your cooling costs.

Use Ceiling Fans

By operating a ceiling fan, you can create a wind-chill effect, making you feel cooler without altering the room's actual temperature. This allows you to set your air conditioner at a higher temperature, reducing its workload and energy consumption. Consequently, your cooling system runs less frequently and consumes less electricity.

Maintain Consistent Temperatures

By setting your thermostat to a moderate and comfortable level, you can prevent frequent cycling of the air conditioner, which consumes substantial energy. Additionally, consistent temperatures reduce the need for abrupt temperature adjustments, which can lead to inefficient cooling and increased energy consumption.

Keeping a steady temperature enables your cooling system to operate more efficiently and maintain a balanced indoor environment. Such results in lower energy usage and decreased cooling costs.

Have Your Unit Serviced Regularly

A trained technician will inspect and clean the various components, ensuring they operate efficiently. The technician can optimize the unit's energy efficiency by addressing any potential issues early on, such as dirty filters or malfunctioning parts.

As a result, the system requires less energy to produce the desired cooling, leading to reduced electricity consumption and lower cooling costs. Timely servicing also helps prevent major breakdowns, avoiding costly repairs and the need for emergency services.

Apply Window Tinting

Applying window tinting can reduce your cooling costs in summer by blocking a significant amount of solar heat from entering your living space. The tinting film acts as a barrier, preventing the sun's rays from penetrating through the windows and heating up your interior.

By reducing the amount of heat gain, your air conditioning system doesn't have to work as hard to maintain a comfortable temperature, leading to lower energy consumption and decreased cooling expenses.

Use a Programmable Thermostat

By actively controlling the temperature settings in your home, you can optimize energy usage. You have the flexibility to program specific temperature levels based on your daily routine.

For instance, during the day, when you're away at work, you can set the thermostat to a higher temperature, easing off the cooling system's workload. As you return home, the thermostat can be programmed to lower the temperature to a comfortable level.

This targeted approach prevents unnecessary cooling when the house is unoccupied, leading to energy savings. Moreover, programmable thermostats enable you to create customized schedules, ensuring efficient cooling during the times you need it most, like waking up or going to bed.

During an energy audit, a trained professional will thoroughly assess your home's energy efficiency and identify areas where improvements can be made. By pinpointing sources of energy waste, such as air leaks, inadequate insulation, or inefficient cooling systems, you can take proactive steps to address them. Ultimately, an energy audit empowers you to make informed decisions about your home's energy usage.

Open Your Vents

Opening your vents can reduce your cooling costs in summer by allowing the cool air to circulate more efficiently throughout your living space. When you open the vents, fresh air enters the room, replacing the warm and stale air and resulting in a more comfortable environment. By doing so, you can rely less on air conditioning, which consumes significant energy and contributes to higher electricity bills.

Proper ventilation promotes natural airflow and can help maintain a moderate temperature indoors, reducing the need for excessive cooling. This simple act of opening vents facilitates the expulsion of hot air, preventing it from accumulating and creating heat pockets.

Preferred Mechanical Services , a locally owned and operated company, provides plumbing, heating, air conditioning, and duct cleaning services. We cater to both commercial and residential areas, providing tailored solutions to apartments, light commercial spaces, and residences. Contact us for 24-hour emergency service.

6 Common Reasons To Replace Your HVAC Unit

Thu, 04 May 2023 16:33:00 GMT

A functional HVAC unit can keep the house comfortable and enhance air quality. However, like other appliances, these devices don't last forever. After some years, you'll have to replace the system to regulate indoor temperatures.

But when is the best time to replace an HVAC unit? Here are the top scenarios when you can invest in a new system.

1. Improve Air Quality

Although many buildings are air-tight and energy efficient, the indoor air can be more polluted if you don't ventilate the house properly. An HVAC unit detoxifies a living space, making it cleaner and healthier. These units have air filters and purifiers to remove harmful vapors, germs, and contaminants. Others even have dehumidifiers that maintain the required humidity. However, older units might no longer be able to provide these benefits.

2. Eliminate Loud Noises

Are you constantly forced to raise your voice whenever you are near the HVAC system? This is a clear sign you need a new unit because the latest devices have become quieter.

Squealing and grinding sounds clearly indicate that it's time to replace the old unit. Squeals could mean that a condenser fan motor is working hard or the blower motor is faulty. You may also hear a buzzing sound that could be a sign of a broken compressor, refrigerant leakage, or damaged parts.

The best way to get a quiet and peaceful home is to replace the HVAC unit. This is particularly vital if the current system is too old or if the device has many worn-down parts.

3. Acquire Consistent Temperatures

One frustration you may face when using an older HVAC unit is uneven heating or cooling in various rooms. The issue could be a leak or clog in the ductwork, poor insulation, or incorrectly calibrated hardware. Calibration can become more challenging as the unit ages.

Buying another device can help you attain consistent temperatures throughout the house. Besides investing in a professionally calibrated HVAC unit, ensure the home is insulated.

4. Lower Repair Expenses

After installation, you must maintain the HVAC unit to ensure it operates optimally. However, there are instances when the system may become faulty, and only a seasoned HVAC technician can fix the damages. If the issues keep recurring and the repair costs increase, consider purchasing a new unit.

The technician may recommend repairs like refrigerant recharge or a fan belt replacement. But, if the HVAC unit is old and needs major repairs, such as a new compressor, you may consider replacing the whole system.

5. Lower Utility Expenses

Although an HVAC system has been efficient during the first few years after installation, it may lose its ability to regulate indoor temperatures over time. Many property owners who face this problem change the thermostat settings to keep the house more comfortable. This may work, but it forces the unit to work hard, increasing the power bills.

When buying a new HVAC unit, pick an energy-efficient model. Select a unit with Energy Star approval and a higher SEER rating. Also, consider the unit's size and choose the one that meets the cooling and heating needs.

6. Boost Property Value

Many potential homebuyers check the HVAC's condition before purchasing the home. If you have an old unit, the property may not sell fast. Buyers may avoid incurring maintenance or replacement costs immediately after acquiring the house.

Besides, older units may not be efficient, which increases running costs. Therefore, get a new HVAC unit to boost your property's resale value before placing the home on the market.

Once you decide to replace an outdated HVAC unit, assign the installation task to professionals. At Preferred Mechanical Services, we can help you pick the right unit size and install the system, making the entire process seamless. Contact us today to learn more about your options.

Tips for Choosing the Right Air Conditioner for Your Home

Tue, 04 Apr 2023 19:22:00 GMT

The right air conditioner can create a comfortable environment in your home, especially when temperatures become too high. Although the decision to install air conditioning in your home is simple, finding the right unit for your home can be challenging. If you make the wrong decision, your energy bills will increase, and the unit might not effectively cool your home.

Read on to discover some factors that affect your choice of an air conditioner.

Room Size

Possibly the most important consideration is to select an air conditioner that matches the size of your room. If the air conditioner is too small, it won't properly cool the room. But a bigger AC is not always better since a unit that is too large for the room will quickly cool the space and then shut down immediately. This shutdown happens before the AC has removed enough humidity from the room.

A very large unit means that you have to constantly turn it on and off to achieve optimum temperature and humidity levels. This can result in energy wastage and reduce the lifespan of the AC units. The best option is to determine the size of your home on your own or with the help of a trained technician. You can also use online calculation tools to know the right AC unit size for your home.

Control Settings

The right control settings can help you easily adjust the temperature of the air conditioner, particularly in a stuffy and hot room. Choose an AC unit with an adjustable thermostat that allows you to control the speed of the fan. The unit should also have a higher setting that allows you to fine-tune the temperature to cool the room more quickly.

You may also prefer a unit that has lower settings for a quieter operation for nighttime usage. The latest AC units also have digital controls for precise temperature settings. For example, smart thermostats allow you to preset and personalize the AC unit. You can even remotely control the units and adjust the temperature. The result is massive energy savings.

Energy Efficiency

Heating and cooling are the main contributors to your home's energy expenses. Energy-efficient air conditioners consume less energy and can reduce your energy bills. The federal government requires all manufacturers to indicate each unit's energy efficiency rating.

Although there are many ways to measure energy efficiency ratings, the Seasonal Energy Efficiency Ratio (SEER) is the most common. The ratio measures an air conditioner's total cooling output versus the unit's electrical power consumption. AC units with higher SEER ratings are efficient and can make your home more comfortable.

While old units have ratings of as low as 6, current US regulations require all new AC units to have a rating of at least 14. Most AC units have a rating of 9 or 10. Anything above 10 is considered highly efficient, but the ultimate choice comes down to your personal preferences. Remember, air conditioners with a high SEER rating will also positively impact the environment.

Type of Air Conditioner

Different types of air conditioners have different operational mechanisms and advantages. Some of the main types to consider include:

These air conditioners can also be categorized into single-stage, dual-stage, and variable-speed condensers. All types of air conditioners require regular servicing to function properly and last long. Preferred Mechanical Services provides air conditioning, plumbing, heating, and duct cleaning services.

7 Ways to Prevent Frozen Pipes

Wed, 01 Feb 2023 18:04:00 GMT

The winter season is here and with it the potential for frozen pipes. Frozen pipes can be a nightmare for homeowners and businesses, resulting in costly repairs and potential water damage. Fortunately, you can take a few simple steps to prevent frozen pipes and avoid the hassle and expense of dealing with the aftermath. Keep reading to learn how you can prevent frozen pipes this winter.

1. Insulate Pipes in Unheated Areas

Insulating your pipes is one of the most effective ways to keep them from freezing. Unheated areas such as basements, attics, and garages can be particularly vulnerable to extremely cold temperatures. It's important to insulate pipes in these areas and any pipes that run through crawlspaces or outside walls.

You can buy insulation sleeves, tape, or foam insulation tubes available at your local hardware store and easily wrap them around the pipes to insulate your pipes efficiently. This will help keep the pipes warm and prevent them from freezing.

2. Seal Air Leaks Around Windows and Doors

Another way to prevent frozen pipes is to seal any air leaks around windows and doors. Cold air can easily enter through these openings and cause the temperature in the area to drop quickly. Sealing gaps or cracks to help keep the temperature inside the house or building consistent.

You can use a weather strip, caulk, or foam insulation to keep your spaces warm and keep cold air out.

3. Keep the Thermostat Set to the Same Temperature Day and Night

Although switching off the thermostat at night may be tempting, it may work against you when it comes to preventing frozen pipes. This is because the air temperature will drop significantly when the thermostat is turned off, which increases the chance that the pipes will freeze.

To avoid this, keep the thermostat set to the same temperature day and night. This will help keep the temperature inside the house or building consistent and reduce the risk of frozen pipes. Additionally, it's a good idea to keep the thermostat set to at least 55 degrees Fahrenheit during cold weather. This will help ensure that your pipes don't freeze.

4. Open Cabinet Doors to Allow Heat to Circulate Around Pipes

If your pipes are located in areas such as bathrooms, kitchens, or laundry rooms, you can help prevent them from freezing by opening the cabinet doors to allow the heat to circulate around the pipes. This will help allow the heat from the room to circulate around the pipes, keep them warm, and reduce the chances of them freezing.

5. Let Faucets Drip Slightly During Cold Weather

Letting your faucets drip slightly during cold weather can help keep your pipes from freezing. This is because moving water is less likely to freeze than standing water.

6. Disconnect and Drain Outdoor Hoses and Store Them Indoors

It's important to disconnect and drain outdoor hoses and store them indoors during cold weather. This will help keep the water in the hoses from freezing and causing the pipes to burst. It's also a good idea to shut off the water supply to any outdoor faucets.

7. Shut Off the Water Supply and Drain the System If You Won't Be Around

If you plan to be away from your home or business for an extended period, it's a good idea to shut off the water supply and drain the system. This will help ensure that any water left in the pipes won't freeze and cause damage.

Preferred Mechanical Services is here to help you with your plumbing, heating, air conditioning, and duct cleaning needs. Our experienced team of professionals is available 24/7 to provide prompt and reliable service. Contact us today to learn more about how we can help keep your pipes safe and warm this winter.

Consider an upgrade in your home from a standard hot water heater to a tankless hot water heater. Along with year-round benefits, you will find many benefits directly related to the holiday season.

1. A Tankless Water Heater Offers Holiday Guests Instant Hot Water

Many families choose to host other guests during the holidays. When you host guests for multiple days, you do not want to constantly run into hot water issues as guests take showers and use the kitchen. The loss of hot water can create major delays. A tankless hot water heater only supplies hot water when needed.

You do not need to worry about a hot water tank constantly refilling and replenishing the hot water. Each time a guest goes to shower, the tankless hot water heater will supply instant hot water so no one needs to feel guilty about using too much.

2. A Tankless Water Heater Helps With Multi-Tasking Needs

As you plan holiday events, you may need hot water to do laundry, run the dishwasher, prepare meals, or shower. When multiple resources go at the same time, the hot water can quickly run out and not work efficiently. An HVAC specialist has the ability to install dual tankless water systems in different locations.

With multiple systems, your home will have hot water access without impacting other sources of hot water. For example, the hot water that goes to your kitchen can run separately from the one that runs to the bathroom. With the multi-point system, you can reduce the amount of scheduling you need to plan for hot water use.

Someone who chooses to use hot water in one room will not need to worry about uses in the other. The simple change can result in a lot less holiday stress.

3. A Tankless Water Heater Offers Energy Reduction

When you plan for the holidays, you will often find a big increase in energy use. You may have Christmas lights and decor set up around the house. You may bake a lot more in your oven than usual. A tankless water heater will help provide a reduction in energy use. Hopefully, the changes will equal out so you do not see a huge increase in energy use around the holidays.

A tankless water heater reduces energy by only supplying water as needed. The tank doesn't need to constantly fill and keep water heated. If you go a day with minimal hot water use, then you will also reduce the amount of energy you use.

When you select a tankless water heater for installation, you can compare the energy use and efficiency for your home to see which ones will help you reduce the most energy.

4. A Tankless Water Heater Doesn’t Operate During Your Holiday Travels

The energy reduction from a tankless water heater will also help if you plan any holiday travels. If you decide to visit relatives for a holiday break, a traditional water tank may replace and replenish the hot water on a daily basis. A tankless water heater will not operate if the hot water is not in use.

You can enjoy your vacation without the need to waste energy on heating hot water. When you come back from vacation and want a shower, a tankless water heater will instantly kick in and provide you with high water temperatures.

Causes and Solutions of Unusual Water Heater Sounds

Thu, 01 Sep 2022 16:09:00 GMT

Water heaters always make a given amount of noise during regular operation. Nonetheless, weird noises can indicate severe underlying problems. Read on to explore various sounds from your heater and what each means.

Hammer Sounds

Also known as a knock, hammer sounds happen due to the abrupt cessation of water flow. This is because the water lacks a place to flow to your plumbing and backpedals to your water heater. Also, if your water lines are not firm, a sudden switch in water flow causes the pipes to shift and knock against each other.

Water hammers do not always stem from your water heater but are destructive to the appliance. For instance, that hammer could cause your pipes to burst or deform the top part of your water tank. To solve knocking sounds, install a hammer arrestor or shock absorber, which absorbs shock waves and protects your heating and plumbing systems from damage.

Humming Sounds

Water heaters have a looped heating element that heats your water. Sometimes, the usual water flow past the unit generates small vibrations that sound like hums. Other times, the components of the elements could loosen up due to poor installation or wear and tear. Loose parts allow water to pass between the tank wall, causing humming noises.

The solution to the hums is to tighten any loose components. First, turn off the water heater and wait for some hours before you inspect the components. Then, if any pieces are loose, tighten the screws and bolts of the affected parts. Alternatively, call a professional plumber to avoid any burns that could happen from water leaks and other electrical accidents.

Ticking and Tapping

Fluctuations in copper pipes' water pressure, expansion, and contraction induce ticking sounds. The noise could also happen due to the usual function of the water heater valve. Sediment build-up, too, can cause ticking and tapping noises.

These sounds are usually not problematic. Provided the shifts in water pressure are not dramatic or frequent, your system will not face damage. However, if the noise persists, and you have copper pipes, turn the water heater's thermostat down by a few degrees and observe whether the noise fades. If the noise is from the valves, get dielectric nipples to replace the heat traps.

Screeches

Screeches and other squeaky sounds happen when the water flow through the valves is over-restricted. In other cases, loose valves could let the air out of your tank and generate screeching or whistling sounds. Finally, if your valve is halfway open, the narrow space creates high pressure, producing noise.

Examine your heating unit's temperature and pressure relief valve if you hear screeches. If unsure of the component's location, look through your user manual. If the sound originates from the relief valve, turn off the tank's electricity, gas, and water. Then, invite a professional plumber for a thorough inspection and repair.

Rumbling and Popping Sounds

Sediment accumulation is a common occurrence in places with hard water. The deposits from various minerals then interfere with the unit's usual function and generate noises. For instance, the expansion that happens when water heats up causes the sediments to rise and brush against the water tank. You then hear rumbles from the interaction between lime build-up and the water tank.

Like rumbles, popping sounds often occur due to mineral and limescale build-up in your tank. As the water heats, steam bubbles form underneath the build-up, generating popping sounds. The solution to the sound is to disintegrate the limescale in your tank. So, call an expert to remove the sentiment and flush your tank every four to twelve months , especially if your area has hard water.

How Different HVAC Components Contribute to IAQ

Tue, 12 Jul 2022 14:22:00 GMT

The quality of air within your premises, known as Indoor Air Quality (IAQ), affects the occupants' comfort and wellbeing. HVAC systems contain various components that work together to protect you from contaminants. Explore how each component enhances your indoor air quality.

Air Filters

HVAC air filters trap particulate contaminants that get into your indoor space. Such particles include pollen, bacteria, dust mites, and fungi. The foreign particles exacerbate allergic reactions in sensitive people. Therefore, the ideal unit for your office or home is the high-efficiency particulate absorption filter, with an efficiency rating of 99.9% .

Due to the nature of air filters' work, particles pile up and clog the unit with time. If you don't clean up and change the filters when needed, the trapped components flow in your indoor space alongside clean air. Also, many air filters only keep out gas or particles. So, if you want a unit that eliminates particles and gas, check the label or consult your manufacturer before installing one.

Humidifiers

The ideal humidity for indoor air should range from 30–55%, and any percentage below the range translates to dry air. Your indoor air dries out if your home's or office's heating system is always in use or you live in an arid climate. Humidifiers add vapor to your indoor air to prevent health problems.

Significant health issues dry air can cause include:

Dehumidifiers

Dehumidifiers reduce moisture from your indoor air. They are essential if you live in an area with high atmospheric moisture levels. Indoor air moisture may not be a big problem if you don't have allergies. Nonetheless, the humid environment provides favorable mold and mildew growth conditions.

Typical culprits of excessive moisture are damp basements, so a dehumidifier is ideal in such areas of your premises. Also, dust mites in your air, clothes, and beddings thrive in humid regions and trigger allergies. Yet, even if none of your family members has allergies, a dehumidifier is vital if you have young children and older adults within the household.

UV Lamps

UV is the ultraviolet region of light. This wavelength region has significant energy levels and can kill microorganisms. UV lamps are not always pre-installed as part of HVAC units, but you can add one to control microorganisms' growth. The mercury vapor in UV lamps emits light at a frequency required to kill given microorganisms.

The best use of UV lamps inside your residential unit is to keep your AC's drain pan and coil clean. That way, you discourage the growth of foreign particles on essential HVAC Components. Nonetheless, be careful because UV lamps might degrade some components. So, confirm that your HVAC can handle a UV lamp light if you want to install one.

Recovery Ventilation

Recovery ventilators come in two forms : energy recovery ventilator (ERV) and heat recovery ventilator (HRV). The role of recovery ventilators is to filter outdoor air and get back the energy from the air. The difference between ERV and HRV is that HRV only gets heat from the exhaust air, whereas ERV recovers heat and moisture.

Recovery ventilators precondition the outdoor air that gets inside your HVAC. As a result, you lower the strain and could reduce the unit size you need. Also, if your premises have cracks that cause infiltration or exfiltration, ERVs and HRVs curb the problem. You can also set up a recovery system in a new or existing HVAC system based on your needs.

Prolonged exposure to indoor air contaminants predisposes you to respiratory illnesses. So, always schedule regular maintenance to keep your HVAC in good shape. If you have more questions or want HVAC maintenance services, contact Preferred Mechanical Services .

Commercial AC Maintenance and Repairs: Essentials and Preparation Tips

Fri, 13 May 2022 17:21:00 GMT

Air conditioners are a common feature in many commercial buildings, and with good reason. These devices ensure occupants have access to quality indoor air, which boosts productivity, lowers the risks of complications like asthma attacks, and keeps workspaces pleasant and comfortable.

Unfortunately, like most other machines, air conditioning (AC) units are susceptible to numerous problems. Common AC issues include fluid leaks, blown fuses, freezing coils, and damaged air filters. The good news is that skilled technicians can fix most of these issues through proper maintenance practices and repairs.

The sections below introduce you to AC servicing and repair and offer tips to help you prepare before technicians visit.

Essentials of AC Servicing and Repair

AC service or maintenance is essential because it prolongs the unit's lifespan, increases efficiency, and creates a more comfortable working environment. The process mainly involves cleaning air filters, fins, evaporator coils, and condensers. An AC maintenance expert also checks fluid levels and inspects the entire unit.

On the other hand, AC repairs restore the system to working order. As a property owner, you can hire expert AC repair services when your unit breaks down or encounters issues that undermine its performance. Popular commercial AC repairs involve replacing elements like fuses, air filters, thermostats, compressors, and condenser fans.

How to Prepare for AC Servicing or Repair

If your unit needs servicing or repair, you can prepare beforehand by doing the following:

1. Scheduling Mindfully

A commercial building should have functional AC units throughout the year. However, these machines become indispensable in hotter seasons, especially summer. Therefore, scheduling annual maintenance services in spring is highly advisable before the onset of summer.

Otherwise, you risk unexpected breakdowns and forcing tenants to work in uncomfortably hot environments.

On the other hand, you should call repair experts and schedule visits immediately when you notice insufficient airflow, water leaks, unusual noises, and high energy bills, among other common issues. The technicians will fix such problems fast and increase the system's efficiency.

While scheduling a visit, remember that the time an expert will take to service or repair your unit mainly depends on factors like the AC's size and damage extent. Therefore, ensure the technicians have access to the equipment for as long as necessary, and you or any other stakeholder is readily available to monitor progress the entire time.

2. Requesting Estimates and Payment Options

Most AC experts provide estimates after inspecting your unit and isolating any pertinent issues. So, don't be afraid to request them.

Once you receive accurate estimates, you can plan and function more efficiently. You don't want to order AC maintenance or repair services without knowing how much they'll cost because you may find your finances wanting when it's too late.

In addition, ask about payment options ahead of time. Reputable AC repair and service companies have established payment systems. Ask about them before the project kicks off to ensure they accept the alternative at your disposal, be it cash, credit cards, or checks.

3. Preparing Pertinent Questions

Commercial property owners should ask AC technicians several questions, depending on their situation, needs, and preferences. For example, if you are interested in smart thermostats and similar devices, you can prepare queries related to vital aspects, such as how they operate and other issues.

Experts can also suggest practical ways to improve your commercial building's indoor air quality. And that is crucial in boosting client satisfaction and retaining tenants. However, most technicians don't volunteer such tips if you don't ask. So, before maintenance and repair start, list all the questions you consider important and ask them when the team arrives.

This guide is for anyone that needs professional AC repairs or maintenance. But, for it to be of any help, you must first choose the best service provider, and then you can fully utilize their services.

When it comes to commercial air conditioners, Preferred Mechanical Services offers the best service and repair. We use trained and skilled professionals to help you solve various AC problems and properly maintain your building's unit to improve efficiency and enhance its lifespans.

Warning Signs That Your Plumbing Pipes Are Frozen

Fri, 25 Mar 2022 03:39:00 GMT

As a property owner, seasons like winter can bring more concerns to the maintenance of your home, especially on the safety of your plumbing system. Some of the most affected pipes are in exterior piles, walls, and exposed pipes running through insulated and non-insulated areas like basements and attics.

However, when you know the warning signs of frozen pipes, you'll quickly seek the right solutions. So, before plumbing problems worsen, watch out for the following warning signs of frozen pipes.

Complete Lack or Reduced Amount of Water and Gurgling Sounds
When pipes freeze, they suffer from clogs or blockage from dust, dirt, and anything that prevents them from allowing water to flow through.
However, sometimes water will come out in reduced volumes. When you open faucets, drains, or sinks simultaneously, you'll notice others are not producing any water unless you close a few of them. Besides not getting enough water, gurgling sounds also indicate that your pipes are frozen. Usually, gurgling sounds suggest that the freezing comes from ice traveling through the pipes.

Ice accumulation can also result from moisture condensation or the collection of ice content, especially those washed through sinks and drains. Therefore, before thinking the lack of water is caused by other plumbing problems, inspect your pipes for ice and other elements blocking them like dust.

Signs of Bulging and Bursting Pipes
When water or other liquids freeze inside your plumbing pipes, water molecules first expand, pushing other molecules to the walls of those pipes. When this happens, your pipes experience increased pressure that bulges them. Sometimes you'll quickly notice the bulging. Other times, bulging can be hard to identify when the pressure isn't considerable.

However, regardless of the pressure levels, the expansion of water and other liquid molecules leads to bulging and bursting pipes over time. In addition, apart from the signs of bulging pipes, watch out for signs of bursting.

Bursting is easily noticeable, especially with colored pipes. Mostly, you'll notice swellings or noticeable cracks. When this happens, it indicates that your pipes are experiencing increased pressure levels. When pressure rises, most pipes fail to balance the air inside and outside. Over time, bulging pipes will eventually burst. Therefore, to prevent the expenses of replacing pipes that burst beyond repair, fix bulging problems on time.

Frost Formation and Unpleasant Smells
Frost formation within pipes means moisture has reached its dew point temperature. Depending on how low the current temperatures are, it can turn into ice or frost when water condenses. Condensed moisture forms crystalline structures inside the pipe walls, causing blockages and clogs.

All the same, signs of frost formation start with the production of milk-like water droplets, especially with the last drops from sinks and drains. On top of that, another sign indicating your pipes suffer freezing issues is an unpleasant smell. Unpleasant odors mostly come from frozen content and dirty clogs accumulating dead organisms. For example, when bacteria enter your pipes due to clogs, they can bring about unpleasant smells.

The Best Option for Dealing With Frozen Plumbing Pipes
Mostly, it's easy to think your DIY skills can easily handle problems with frozen pipes. However, unless such issues are minor, like getting insufficient water, significant issues will need the help of a professional.

An expert is the best consideration for seriously frozen pipes. Because of this, you can hire highly experienced and trustworthy professionals. Preferred Mechanical Services will quickly deploy an experienced plumber to inspect and rectify your problems before they worsen. So, when the need arises, contact us for prompt and reliable plumbing services. With our technicians, nothing disturbing your pipes will go unsolved.

Telltale Signs of HVAC Duct Damage

Fri, 28 Jan 2022 23:32:00 GMT

The HVAC duct system plays a critical role in efficient heating and cooling. The ductwork supplies different parts of the house with fresh air and channels stale air back to the HVAC system. Thus, damaged ductwork requires repair to restore the HVAC efficiency. Below are some signs that might mean ductwork damage.

Debris Around Air Vents

Ideally, the air that flows out of your supply vents or registers should be clean. After all, such air comes from the HVAC system, where the filter cleans it. If dirty air comes out of the vents, you can be certain it picked up most of the dirt from the ductwork.

Thus, you should be worried if you notice dust and debris around the vents. Such debris usually appears if the duct that connects to the vent has suffered damage, such as a disconnection that allows air to infiltrate it. Such unfiltered air will enter your ductwork along with debris.

Impaired Heating and Cooling

Duct damage leads to impaired heating and cooling if the damages trigger heat losses or air infiltration. For example, during the cold season:

All these issues will leave some parts of your house colder than others.

Increased Duct Noises

You should also suspect damage if the ductwork is noisier than usual. Typical causes of duct noises include:

Duct noises due to expansions and contractions are normal. The other noises are not normal and point to duct damage.

Unexplained Respiratory Problems

Air should flow from the HVAC system to your rooms without external contamination, but that is not always the case. Damages to the duct material will allow contaminants to enter the duct system and circulate in the house.

The contaminants can include mold, dead animals, and dust. These contaminates foul up your indoor air and affect your respiratory health. The elderly or those with chronic health problems are often more susceptible to such health problems than others. For example, asthma sufferers might suffer flare-ups, and those who are allergic to the contaminants might develop allergic reactions.

Visible Duct Imperfections

Few people inspect their ductworks. However, even a cursory visual inspection of the ductwork can reveal physical damages. Such signs of damage include tangled ducts, crushed ducts, visible cracks, and disconnected duct joints. Aging, physical impacts (for example, from fallen tree branches), and restricted airflow can cause such damages.

Increased Energy Bills

Lastly, several HVAC problems can cause increased energy bills, including duct damages. Discover some ways duct damages can increase energy consumption:

Such things lead to impaired heating and cooling, which forces the HVAC system to increase its output. The increased output leads to increased energy consumption. Thus, the HVAC will consume more energy than usual but still struggle to maintain comfortable temperatures.

Many forms of HVAC issues, including duct repairs, require professional input. Preferred Mechanical Services is a professional HVAC company with years in the industry. We handle new installations, repairs, and maintenance. Contact us for all your duct or general HVAC needs today.

Get Ready For Winter With These Four Tips

Thu, 25 Nov 2021 15:32:00 GMT

As winter is starting to approach, it's time to prepare your home. The cold weather can cause a lot of damage if you aren't careful. Pipes can burst, and your HVAC system may stop working on the coldest day of the year. Luckily, there are many ways you can get ready for winter and reduce your risk of experiencing any complications. If you would like to know more, check out these four tips to get ready for winter.

1. Protect External Pipes From the Cold

As the temperature drops, pipes (especially external pipes) have an increased risk of freezing. This occurs when the trapped water in the pipe freezes. Since water expands when it freezes, it could cause the pipe to burst. Luckily, there are many ways to prevent pipes from freezing.

Start by insulating any exposed pipes, especially those in the attic, crawlspace, and basement. Since these areas are not always temperature controlled, they can become significantly cold in the winter, allowing the pipes to freeze. You should also use faucet covers on outdoor faucets. Alternatively, you could shut off the water to the drain and empty it. If there's no water inside the faucet, there's no way ice can form and expand.

2. Get Your HVAC System Serviced

Before winter hits, you should have your HVAC system serviced. Not only will this ensure the system keeps you warm during the cold months, but it helps keep the system more efficient, which reduces your energy bills.

An HVAC technician will check several parts of the system to ensure they are clean and undamaged. Any damaged pieces are replaced or repaired, and the system is cleaned to help with efficiency. Don't forget to occasionally have the ductwork cleaned and maintained too. Ducts can develop holes and horde dust/debris. This can affect the efficiency and effectiveness of the system, but it can also affect your indoor air.

3. Check Your Sump Pump

Some homes rely on sump pumps to help relocate excess water. This is common on properties with poor drainage, hard soil, etc. They are often installed inside the basement or outside the home. For example, you may have a French drain that leads to the sump pump. The sump pump well holds the excess water while the pump pushes the water through various pipes and drains it toward the road or storm drain.

Even a little bit of standing water from poor drainage or sudden flooding can cause major damages. Naturally, water can lead to mold and wood rot, but it can also erode your landscaping, damage your home's foundation, attract pests, and harbor bacteria. If the standing water freezes, it also becomes a slipping hazard for those entering your property, for which you could get sued.

4. Have Your Water Heater Maintained

Finally, during those cold winter months, you'll want plenty of hot water, so make sure your water heater is well maintained. A repair technician can spot and repair any damaged parts, but they will also clean out the system to remove excess sediment that has been left behind. They may also adjust the temperature if your water seems too hot or too cold.

While checking your water heater, your technician may suggest putting in some insulation. Insulation around the pipes and the actual tank can help keep the water hotter while using less energy. Alternatively, newer models of water heaters may naturally have better-insulating properties. You could avoid the tank altogether by installing a tankless system.

Is Your Furnace Leaking? Here's Why

Mon, 13 Sep 2021 21:50:00 GMT

Your furnace can create some condensation during normal operation. However, an unusual pool of water under the furnace may point to a problem with the furnace. You might worry that your unit may become faulty once you notice a large puddle or a steady drip underneath.

Thankfully, a leak may not always require any major repair work. But still, leaking water can trigger the growth of harmful mold that might expose you to serious health conditions. Also, prolonged issues with your furnace may lower your HVAC system's lifespan in the long run.

You may want to contact your HVAC expert if you notice any unexplained leaks under your furnace. Learn more about the reasons that could cause your HVAC furnace to leak and what you can do to prevent more problems.

1. Clogged Furnace Filter

Typically, furnace filters trap dust and other contaminants that may otherwise affect the unit's performance. If anything blocks these filters, air may not flow freely into the coils. Eventually, the coils may develop an ice layer and freeze up. When the ice melts, a large pool of water can collect at the furnace's base.

Additionally, dirty filters can easily raise your heating bills because now, the circulation fans have to work harder to ensure an even air distribution. With time, your furnace may be unable to maintain comfortable temperatures in every part of your house.

Your HVAC expert might suggest periodic maintenance to keep a close eye on your system. You may need to replace your filters now and then to prevent leaks and keep your furnace in top condition.

2. A Leaky Humidifier

Built-in humidifiers balance out the indoor humidity inside your home. They work by adding moisture to the surrounding air. In doing so, humidifiers increase the level of humidity if your system detects a drop.

While they're meant to add an extra layer of comfort, built-in humidifiers can also cause leaks around the furnace area. Since a humidifier uses water to do its job, a plumbing line will be needed to ensure an uninterrupted water supply.

Over time, the line could deteriorate (mostly due to high water pressure) and form cracks that allow water to leak through. Water may eventually pool at the base of your furnace.

You may not always know when you have a clogged or leaking built-in humidifier. But if you see a leak, you can examine the area around the drain line or water feed line. However, you're better off letting a professional handle the problem to avoid costly mistakes.

3. A Faulty Heat Exchanger

A high-performance furnace can give off condensation as a heating byproduct. The primary and secondary heat exchangers obtain heat energy from the exhaust gases in circulation. As a result, the gases lose some of their heat in the form of condensation. The condensate may leak out and form a pool of liquid near your furnace.

Usually, a leaky or broken heat exchanger may be accompanied by other symptoms such as:

A bad heat exchanger may cost you a lot in repairs if you don't act quickly. Sometimes, only a full furnace replacement can suffice.

Don't ignore any unusual behavior from your heating system. Immediately you notice a leak, contact us at Preferred Mechanical Services .

Common Commercial Plumbing Issues

Tue, 13 Jul 2021 19:08:00 GMT

Plumbing is an essential yet overlooked part of any commercial building, whether it is an apartment, retail store, office complex, restaurant, or warehouse. It promotes health and safety by getting clean water in and waste out. When a plumbing problem arises, it can have adverse effects on your business, including discontinuing operations, increasing customer dissatisfaction, requiring costly repairs, and attracting municipal fines. Learn common plumbing issues for businesses.

Leaks In commercial buildings, leaks are rampant in pipes, toilets, sinks, and faucets. Although a leaky faucet may appear like a minor issue, it can waste gallons of water when unrepaired, resulting in high water bills. Leaks in pipes hidden in walls can be detrimental and cause water damage, mold problems, and structural issues when the water pools in the basement. Also, severe leaks can be extensive to repair, especially if they involve worn-out pipes and appliances. A good indicator of plumbing leaks is skyrocketing water bills for no apparent reason.

Hot Water Supply Issues Some commercial water heaters fail to heat water to the desired temperature. Consequently, you may experience hot water-related problems such as lack of hot water, too much hot water, or water that takes too long to heat. This can be a considerable inconvenience for businesses such as spas, hairdressers, and medical facilities that require hot water for their operations. Among the causes of water temperature issues for commercial buildings include a faulty heater, a bad gasket, inadequate water pressure, a stuck valve, and a leaking water tank. A commercial plumbing company can help determine the cause of hot water supply issues and fix them.

Clogged Drains Since commercial properties have vast volumes of waste going through their drainage systems, they are susceptible to clogged drains. Among the common reasons for clogged drains is a misuse of kitchens and toilets in commercial settings. People tend to use these facilities less considerably than they would in their homes.

In toilets, for instance, people may flush items like paper towels, feminine hygiene products, bandages, diapers, wet wipes, and dental floss. Similarly, they might dump grease, food waste, soap, coffee grounds, and starches in commercial kitchens. All these items get stuck in pipes and clog the system.

Sewer Smells Sewer smells are not only noxious but also can affect your business by scaring away customers and ruining your business perception and reputation. They emanate from dry pipes, clogged drains, faulty seals, broken air vents, and improperly installed vent pipes.

Faulty Internal Toilet Components You might find broken toilet handles and running toilets in commercial buildings. Since these handles are fragile, they wear out quickly after continued use. Rather than spend time and money replacing toilet handles frequently, install innovative technologies like motion-activated flushing systems. They are durable, hygienic, and low-maintenance, saving you money in the long run. A broken or leaky flapper, overflowing water, and an incorrectly positioned refill tube can lead to running toilets, jeopardizing your employees' and customers' bathroom experience. Also, they can block your toilet and septic system. Call in a professional plumber to fix this issue once you spot it.

Low Water Pressure Low water pressure is problematic for businesses, especially in the food sector, as they lack adequate water to wash hands, clean food, and maintain tidy spaces. This may also influence customers' ability to wash hands and stay safe, particularly with the ongoing COVID-19 pandemic. Low water pressure can be an issue on its own or signal leaks in plumbing or broken pipes. If you encounter any of these commercial plumbing issues in Indianapolis, call the experts at Preferred Mechanical Services .

4 Reasons Your AC Is Not Blowing Enough Cool Air

Thu, 13 May 2021 10:33:00 GMT

If you recently turned on your household air conditioner for the first time this season and quickly realized that it is not blowing as much cool air into your home as it used to, then you are likely wondering what the cause of this problem is.

The truth is that there are many central AC problems that can cause your HVAC system to blow less cool air into your home than it used to or blow air that is not as cool as it should be.

Read on to learn four reasons why your AC may not be blowing enough cool air into your home and the solutions to these common problems.

1. Dirty Air Filter

Many homeowners do not realize that efficient operation of their home cooling system relies on the replacement of the furnace filter on a regular basis just as efficient operation of the furnace does. For this reason, some people neglect regular furnace filter maintenance during the summer, which can lead to a reduction of cool airflow from the AC into the home.

An air filter covered in dust and other particulate matter obstructs proper airflow into the HVAC air handler. When less air enters this handler, less air is cooled and then sent into the air of the home.

Ideally, you should inspect your HVAC filter once a month during all seasons of the year and change it when it begins to appear dirty.

2. Refrigerant Leak

A potential cause of an air conditioner that begins to blow air into the home that is much less cool than it used to be an AC refrigerant leak. The refrigerant in your air conditioner absorbs heat in the air to cool the air off. When your air conditioner contains less refrigerant than it should due to a refrigerant leak, it can begin to cool the air in your home much less efficiently.

A few additional signs that your air conditioner may be leaking refrigerant include an AC that makes a hissing noise when it is running, ice on the exterior of the AC unit, and an AC that emits an unusual chemical smell.

If you suspect your AC may be leaking refrigerant, contact an HVAC expert who may be able to repair the leak and replace the refrigerant that was lost through the leak.

3. Duct Leaks

Your HVAC ducts are made of many pipe sections that are joined together with special sealants. Over time, these seals can deteriorate or loosen and cool air can begin to leak out of them.

Both your furnace and your air conditioner send heated and cooled air into your home ductwork, where this air is then distributed into home heating and cooling vents. When one or more ducts begin to leak cooled air into the airspaces in your walls, floors, and ceilings, less cool air enters the rooms of your home.

To fix the loss of cooled air caused by duct leaks, have an HVAC expert examine your ducts and fix any leaks that they find.

4. Dirty AC Coils

Most household air conditioners are equipped with two types of coils: evaporator coils and condenser coils. Both sets of coils must be kept relatively clean and free from dust and dirt buildup for efficient AC operation. When these coils become dirty, your air conditioner can begin to send less cool air into your home.

To keep your AC coils and all other AC components clean and working as efficiently as possible, have an HVAC expert clean your air conditioner and perform other maintenance tasks at least once a year.

During this routine maintenance service, they will clean all AC coils, measure airflow through the evaporator coil, check for refrigerant leaks, and clean and inspect many additional AC components to help keep your air conditioner working as efficiently as possible.

4 Signs Your Sump Pump Has a Problem

Fri, 09 Apr 2021 14:00:00 GMT

You don't always get a warning that your sump pump isn't working. The first sign of trouble is flooding in your basement.

However, sometimes, your pump gives signs that it has a problem before it breaks down completely. What should you look out for?

1. Your Pump's Cycle Has Changed

A sump pump should settle into a predictable operating cycle. It turns itself on when it detects a certain level of water in its pit; it then turns off again after it pumps out the water.

Sometimes, you can tell that something isn't right by a change in the way a pump cycles. Sometimes, it doesn't turn on at all or it cycles constantly and doesn't turn itself off. Or, the pump might seem to work at the right times, but it takes longer than usual to do its job.

These problems are often down to problems with the pump's float or switch. These devices monitor water levels. When water reaches a certain level, they should start up the pump. They should then shut it down when the level recedes again.

If the float is stuck or broken, then the pump will struggle to know when to start and stop. For example, the pump might stay on all the time or cycle on and off repeatedly if the float sticks in one position even if there isn't that much water in the pit.

2. Your Pump Makes Unusual Noises

All sump pumps make some noise as they work. You get used to this noise once you've heard the pump cycle on and off a few times.

However, you should listen out for unusual noises when the pump is on. These noises can be a sign that something is wrong.

For example, if your pump's volume suddenly gets a lot louder, then it might have a bearing problem. If you hear banging, rattling, squeaking or grinding noises, then the unit's fan might be damaged or stuck. You might also have a motor fault.

If the pump also vibrates a lot when it makes unusual noises, then you probably have an impeller problem. The impeller pulls water into the pump. If it brings in a hard or large lump of debris, then the object might bend or break parts of the impeller. If it loses balance, it wobbles and makes the pump vibrate.

3. Your Pump Looks Rusty

Sometimes, a problem pump works and sounds OK, but you can see signs of potential damage. For example, you might spot brown discoloration that looks like rust.

While pumps sometimes do suffer from battery corrosion, this discoloration might also be a bacterial problem. Some bacteria feed on iron in a water supply and then create a rusty residue.

If this residue builds up, then it can turn into a gel. If the gel gets inside your pump it can affect the flow of water through the unit. It can also clog up working parts. Eventually, the pump could overheat or break down.

4. Your Pump Trips Its Circuit

Sometimes, you only notice a problem with a pump when something else goes wrong. For example, if your pump regularly trips its electrical circuit when it powers on, then you know that all is not well.

If your pump hasn't had any electrical problems in the past, then it probably has an internal fault. For example, it might have a loose or damaged wire. Or, the pump's impeller or switch might be damaged or stuck. A faulty motor that is trying to draw too much power can also trip a circuit.

Frequently Asked Questions About HVAC Duct Cleaning

Wed, 13 Jan 2021 15:58:00 GMT

Your HVAC system cannot provide your home with clean, climate-controlled air without its network of ducts. Unfortunately, these ducts can get clogged with dirt and other debris, potentially circulating contaminants and allergens throughout your home. Professional duct cleaning services can eliminate this unhealthy problem.

Whether you have a respiratory issue to worry about or you simply don't like all the dust that seems to accumulate in your residence, you can benefit from a greater understanding of HVAC duct cleaning services. Start by examining the answers to these frequently asked questions.

How Do HVAC Duct Systems Work?

HVAC duct systems guide cooled or heated air along preset pathways to various rooms of your home. The main duct trunk connects directly to the HVAC unit containing the evaporator and blower assembly. It branches out into separate ducts that empty into rooms through openings called registers.

In addition to the registers that send treated air into your living spaces, your HVAC system also has return registers that pull air from the living spaces into a box called a plenum. The blower then draws this air through the system again for fresh heating or cooling.

Why Do HVAC Ducts Require Cleaning?

HVAC ducts tend to collect whatever airborne debris your household air may contain. Some types of duct materials, such as fiberglass and fiberboard, have special problems in this regard. Fiberglass ducts can actually release fiberglass into your air, while fiberboard can foster mold relatively easily.

Your home's HVAC system most likely uses a combination of sheet metal for the rigid ducts and flexible, insulated plastic for places where the ducts must bend. However, even these materials can accumulate dust, dirt, pet dander, hair, mites, and pollen over time.

Dirty HVAC ducts can cause numerous problems for homeowners. A system clogged with debris cannot operate as efficiently as it once did, potentially raising your utility bills and forcing you to work the system overly hard. The extra burden on the HVAC system may then shorten its lifespan.

Debris in your HVAC system can also harm you or your loved ones. If you have trouble with allergies, asthma, or lung disease, you may suffer from serious health problems from the allergens and dust blowing through your ducts. The extra dust also makes house cleaning a more exhausting project.

How Frequently Should You Have Your HVAC Ducts Cleaned?

Different homes may need HVAC duct cleaning at different intervals. A household whose members suffer from breathing problems, for instance, may need relatively frequent duct cleaning. As a general rule of thumb, you should count on having your HVAC ductwork and registers cleaned every three to five years.

You may also schedule an HVAC duct inspection and cleaning whenever your system starts to show obvious signs of trouble. Watch for mold accumulation on vents, an increase in household dust, pests hanging around registers, or an unexplained spike in your heating or cooling expenses.

What Duct Cleaning Steps Do HVAC Professionals Take?

Duct cleaning usually calls for professional skills, tools, and procedures. Not only can the dirt and debris hide in areas impossible for non-technicians to reach, but the close-range exposure to mold and other toxins could also damage your health. You might even damage the ducts in your efforts to clean them.

Your HVAC technicians will first inspect the entire duct network with special cameras. They will then attach a vacuum machine to the system, seal off all the registers, and employ suction power to pull dirt and contaminants out of the ducts. In addition to cleaning each duct, the technicians may also clean other HVAC components.

4 Benefits of an Oil-to-Gas Furnace Conversion

Wed, 18 Nov 2020 13:02:00 GMT

If your home has an oil-burning furnace and it's been working fine so far, you may not have thought much about switching fuel sources. However, you should know that your HVAC system is a big source of energy use in your home, and upgrading to a more modern heating solution can provide several benefits. Here are four reasons to consider an oil-to-gas furnace conversion. 1. Better Energy Efficiency While it's true that heating oil has a really high heat content by volume compared to other fuel, this doesn't mean that oil furnaces are the most efficient type. Natural gas furnaces have seen several more technological advances than their oil-burning cousins. Converting to a more energy-efficient furnace can result in a significant reduction in your monthly energy bill. A metric called Annual Fuel Utilization Efficiency (AFUE) measures the efficiency of a furnace. AFUE is a number between 0 and 100 that represents the percentage of fuel that is converted into heat. A high-efficiency gas furnace will often have an AFUE between 90 and 97 . New oil furnaces often have an AFUE between 84 and 90 , but an old or poorly maintained unit can drop to 60 AFUE or less. 2. Lower Environmental Impact Improved furnace energy efficiency doesn't just affect your energy bill. Converting to a gas furnace is also a great option for homeowners who are environmentally conscious. Natural gas has long been considered the cleanest fossil fuel, as gas combustion produces markedly lower particulate and carbon dioxide emissions than other fuels. Switching from oil to natural gas also reduces your environmental impact indirectly. The US has abundant natural gas resources, while a large percentage of oil is imported. International transport of resources such as crude oil is a source of environmental pollution, and switching to natural gas reduces reliance on these supply pipelines. 3. Less Maintenance Heating oil is unstable and produces several byproducts during combustion. Failing to clean and maintain an oil furnace can result in a premature breakdown or reduced efficiency. Additionally, a technician must frequently clean filter elements, burner nozzles, and pump strainers to ensure that your furnace runs at optimum efficiency. The storage of heating oil also presents its own problems. Contamination by water and bacteria can cause heating oil to break down and form a sludge inside of storage tanks. This sludge can cause problems for your furnace by clogging fuel lines and burner nozzles; and since it is non-combustible, the furnace is out of operation until a professional can deal with the problem. 4. No Need to Monitor Fuel A reliable source of heat in the winter and during emergencies is paramount for any home. Since homes with oil heat rely on fuel oil deliveries, there is always a chance that your tank could run out of oil or the delivery could be interrupted when heating is essential. Furthermore, letting your tank get too low can stir up sediments in the bottom of the tank that can clog the system. Heating your home with natural gas is much more convenient because you don't have to keep a constant watch on your fuel levels. Instead, gas is available at all times through an underground line that runs directly to your home. This gives you peace of mind that your home has a readily available source of heat any time it's needed. An oil-to-gas conversion is a great way to save money, reduce pollution, and heat your home more reliably. Remember these tips when your home is ready for a new furnace, and rely on us at Preferred Mechanical Services for more HVAC tips and quality service.

What You Should Know About Your AC Evaporator Coil

Fri, 11 Sep 2020 17:18:00 GMT

The evaporator coil is one of the most important parts of your central air conditioner, but many homeowners never see it and aren't familiar with how it functions. Understanding the role of the evaporator coil will help you keep your air conditioner in good condition and make it easier to get to the bottom of certain AC problems. Here is everything you should know about your AC evaporator coil.

What Is the Evaporator Coil?
The evaporator coil is the part of your air conditioner that directly cools the air that comes out of your vents when you use your AC. The coil is installed in an A-frame configuration above the indoor furnace and air conditioner. The coil consists of several aluminum fins on each face and copper tubing on the sides that circulates refrigerant.

How Do You Protect Your Evaporator Coil?
Your evaporator coil relies on two elements to cool your home: airflow, and refrigerant. If there is an airflow blockage in your system, it will often cause the coil to freeze over as it isn't able to absorb heat from the air. Common sources of airflow blockages include dirt buildup directly on the coil, a dirty furnace filter, or obstructions around the outdoor condenser.

Your evaporator coil can also freeze if it isn't supplied with enough refrigerant. This is because the compression and evaporation effects inside the AC will continue at the same rate, but the low volume of refrigerant will cause the coil to reach below-freezing temperatures. If you notice that your home isn't getting cool or hear a hissing sound near your AC, call a technician for a refrigerant recharge to keep your coil in good shape.

What Are the Signs of Evaporator Coil Damage?
When there is a problem with your evaporator coil, you may notice several different symptoms when using your air conditioner. One of the most common is warm air from your vents when you use your AC. This can occur if the coil is not able to remove heat from the air effectively due to dirt buildup or low refrigerant.

If your evaporator coil isn't cooling properly, you may also notice a change in your air conditioner cycles. If airflow to the coil isn't restricted but your home isn't cooling, it can cause your AC to run much longer as it tries to reach the temperature set by the thermostat. On the other hand, a dirty or frozen evaporator coil can cause your AC to cycle on and off more frequently than it should.

Should You Repair or Replace Your Evaporator Coil?
Deciding whether to repair or replace the evaporator coil depends on a number of factors. If your system is more than a decade old, it may be nearing the end of its life. Replacing the coil or opting for a complete AC upgrade could both solve the problems you are having with the coil and provide the benefit of improved system efficiency.

If your system is relatively new and there are no signs of corrosion on the coil, repair may be a better option. This is especially true if repairing the coil would cost less than half of what it would take to replace it. Sometimes, cleaning the evaporator coil may be all that it takes to restore its performance. You can do this at home with a commercial foaming coil cleaner and a stiff bristle brush.

If you have never thought about your AC evaporator coil before, now you know what it takes to maintain it and why it's so important. Keep these tips in mind, and contact us at Preferred Mechanical Services for all your HVAC needs!

Factors That Affects an Air Conditioner's Longevity

Wed, 15 Jul 2020 22:26:00 GMT

Air conditioners are usually a big investment, so most people want their systems to last the longest time possible. Below are some of the factors that determine how long an AC lasts.

Local Climate
The local climate determines how hard and how low the AC has to lower the house temperature. Moderate temperatures ease the AC's workload. Hot temperatures mean the AC has to work extra hard to cool the house.

Secondly, the length of the hot season determines how many times you use the AC each year. The more you use the AC, the more wear and tear it experiences. An extremely hot and lengthy summer reduces your AC's lifespan.

Airflow Restrictions
Proper airflow contributes to AC efficiency. The AC needs to get fresh air, cool it, and distribute it throughout the house without blockages. Thus, your AC will overwork if:

The air filter is dirty and restricts airflow.
The outside unit sits in a tight area (for example, between the wall and a fence) that denies it good airflow.
Something has crushed the ductwork and reduced its capacity.
House contents block the registers.

The more the air restriction is, the faster the AC will degrade.

Placement
The outside unit of the AC is not as protected as the inside unit. The outside unit's exposure to weather elements and other things can cause damage and shorten the AC's lifespan. Discover some of the things to worry about.

Acid Rain
Most parts of the AC are metal, which corrodes. Some areas receive acid rain, which causes or accelerates corrosion. Prolonged exposure to acid rain can lead to premature damage to the condenser coil.

Dog Pee
Dog pee is also acidic and can corrode the outside AC unit. Mind this risk if you have a dog and they can access the AC unit.

Corrosive Contaminants
Corrosive particles in the air can also contribute to AC corrosion. For example, if you store or use pool chemicals near the AC, some of the chemicals might land on the metallic parts and trigger corrosion.

Flooding
Flooding can affect a condenser unit in a low-lying and poorly drained area. Floodwater can clog the condenser coil with mud, which restricts airflow. Constant exposure to water also encourages corrosion.

Care
An efficient AC lasts longer than an inefficient one. Proper AC maintenance ensures it always runs efficiently. Below are some of the maintenance practices:

Keep the AC clean. Dirt increases the friction of moving parts, prevents air circulation, and prevents heat dissipation.
Replace the air filter. A dirty filter restricts airflow.
Get regular professional maintenance.

You should also fix malfunctions as soon as they occur. For example, you might overwork the AC if you continue to use it with low refrigerant.

Sizing
Your AC works best if its cooling capacity matches your cooling needs. Some of the factors that affect AC sizing include:

House size
Floor configuration
Number of rooms
Size of household
Local climate

Both oversized and undersized ACs don't run efficiently. An undersized AC has to struggle to produce the required cooling capacity. An oversized AC cools too fast and runs shorter (and numerous) cycles. Both strain the AC and accelerate its wear and tear.

Usage
Lastly, the AC experiences wear and tear every time it runs. Thus, an AC that runs 12 hours every day will wear out faster than AC that only runs six hours every day. Turn off the AC if you don't need cooling, for example, if you are away from home for an extended period.

4 Signs You Need a New Air Conditioning Unit

Wed, 13 May 2020 08:24:00 GMT

As summer months approach, you start to prepare both the outside and inside of your home for the season. A vital step in getting ready for the heat is to ensure you have an air conditioning unit that functions properly. Certain signs signify you need a new unit. Ultimately, if you purchase a new unit, you may save yourself money and prevent your unit from failing when you need it.

Here are four signs that you might need a new air conditioning unit.

1. Air Conditioner Is Over 10 Years Old

On average, an air conditioner lasts around ten years. The lifespan of your unit depends on how frequently you use it as well as how well you maintain it. For instance, if you only use your air conditioner a few hours a day, a few months of the year, your AC may last 10 years or possibly longer. To get the most out of your unit, you should make sure you're changing the filter regularly.

Even if your air conditioning is still working after 10 years, you may want to replace it. Older units are less energy efficient. They use more energy to keep your house at a comfortable temperature, which increases your energy bill.

As you determine whether to replace your unit and what new model to purchase, you want to look at an air conditioning's energy efficiency ratio (EER). The EER is a ratio that compares the thermal units to the power input. It's a fraction comparing the BTUs to the watts of power an AC uses.

You want to aim for a higher EER because these are the most energy-efficient units. Moreover, they'll save you money on your energy bills while keeping your house cool. One way to tell if an air conditioner has a high EER is to look for the ENERGY STAR label. These units rank as ones that are most known for their energy efficiency.

In addition to saving you money, an energy-efficient AC is better for the environment. You'll need less electricity to run your unit to keep your house at a comfortable temperature. By using less electricity, you're reducing your carbon emissions. Carbon dioxide is a greenhouse gas that causes atmospheric changes that alter climates throughout the world.

2. Air Conditioning Unit Needs a Costly Repair

Chances are, if your AC unit is older and requires a costly repair, you may want to consider purchasing a new unit instead. When making this decision, you want to compare the cost of the repair with how long you estimate the AC will run. Additionally, you want to consider the cost of the repair versus buying a new unit altogether. Sometimes, you'll save money in the long run by buying a new AC rather than repairing your old one.

3. Energy Bill Is High

Even if your AC is running and effectively cooling your home, an upgrade is still beneficial if you notice your energy bills are starting to increase during the without any reason. To compare usage, you might want to look back at last summer's energy bills and evaluate how much your electric bill rose when you were running your AC then.

4. Air Conditioner Uses R-22 Freon

Freon is the refrigerant that cools the air before it exits your unit. While R-22 Freon was common in units at one time, air conditioning manufacturers no longer use it. This refrigerant is highly flammable. It also releases greenhouse gases when you open the tank, which contributes to global warming. If your unit still uses this refrigerant, a new AC system may be best for your home.

Before summer is here, you might want to purchase a new air conditioning unit. Sometimes, you're spending more money on your energy bills with an older unit. Additionally, older air conditioners don't cool as well and may cost you in repair expenses.

4 Signs of a Furnace Gas Leak

Mon, 16 Mar 2020 08:41:00 GMT

Natural gas furnaces are the most popular type of furnace in the U.S., with 48 percent of homes using natural gas for heat. While modern gas furnaces have a low failure rate, you should still know the signs of a gas leak so that you can take action if necessary. Discover four signs of a furnace gas leak that every homeowner should know. 1. Sulfur Smell Pure natural gas is odorless, but gas manufacturers are required by law to add a chemical called mercaptan so that leaks are detectable by smell. Mercaptan has an odor that most people describe as sulfur-like, or similar to rotten eggs. If you have a lingering sulfur smell in your home with no known source, your furnace is the first place you should check. You may be able to detect the smell of mercaptan faintly from your home's vent registers. In other cases, you may only be able to smell it directly around the furnace itself you have a larger leak. 2. Hissing Sound Natural gas is pressurized inside the lines that run to homes, as well as inside the heat exchanger of a furnace. When a leak exists, the pressure of the gas escaping will often create a distinctive hissing sound. You should listen for leaks occasionally while the furnace is not running, as the noise of the blower motor can sometimes drown them out. If you hear hissing but are not able to pinpoint the source, you can use the soap test to help you track it down. Turn off your furnace, soak a cloth in soapy water, and run it along any exposed gas lines around your furnace, as well as the heat exchanger. Bubbles will appear in the soapy water at any points where gas is escaping. 3. Dying Plant Life While natural gas is not directly toxic to plant life, it will kill them by disrupting the soil that they grow in. Natural gas displaces oxygen in soil and promotes the formation of hydrogen sulfide gas. This gas inhibits nutrient absorption in plant roots, causing plants to grow sparsely and eventually die out. Indoor gas leaks can cause houseplants to wither and die, so you should keep an eye on the health of your houseplants if you have a gas furnace. Sometimes, gas leaks can occur underground in the gas lines running to your home. This will often result in dead patches of grass in your lawn as the gas leaks up to the surface of the soil and damages the roots of the grass. 4. Health Symptoms Breathing natural gas is dangerous to living things because the carbon monoxide it contains prevents blood cells from delivering oxygen through the body. Health symptoms of a gas leak can begin with flu-like symptoms such as headache, fatigue, eye and throat irritation, and nausea. More advanced gas exposure will lead to dizziness, confusion, and possibly unconsciousness and death. If you have pets in your home, you should know that they can be more sensitive to breathing gas than humans and may begin to show symptoms more quickly. If your pets display unusual behavior like lethargy, vomiting, or difficulty walking, you should take action immediately. Evacuate the home and contact your gas company so that technicians can inspect your home for leaks. Knowing the signs of furnace gas leaks and how to respond appropriately is essential for the safety of everyone in your home. Keep these warning signs of gas leaks in mind, and contact Preferred Mechanical Services today if you suspect a leak or any other problems with your heating and air.

3 Tell-Tale Signs of Plumbing Problems

Mon, 13 Jan 2020 19:54:00 GMT

Homeowners need to know how to recognize leaky plumbing, for even minor issues with water pipes can cause significant damage. If you own a home, here are three tell-tale signs of leaky pipes to watch out for. 1. Sounds of Running Water
Any water you hear run when no one is using a faucet or appliance is a sure sign that something is amiss, for water should not run when everything is turned off. If you hear water run, check all of your home's faucets and appliances that use water to make sure everything is indeed off. Often, the running water is simply the result of a faucet that's not completely in the off position or an appliance button that someone pressed by mistake without realizing it. If everything is definitely off, then there's water running somewhere it shouldn't be. Use your ears to try and identify where the sound is located and then, feel around that area to see if there's excess moisture. Once you identify what part of your home's plumbing is leaking, you should immediately shut off water to that part of the house. You don't want to shut off the flow of water until you identify the problem area, for sound is your clue to the problem. After you know where the problem is, though, you want the water shut off to prevent further leakage and possible damage. You'll need to close a shut-off valve to stop the flow of water. If a feature is leaking, you may be able to stop the flow to just that feature with a localized shut-off valve. For example, many sinks have an under-sink shut-off valve. If no shut-off valve is available, you can turn off your home's main shut-off, which will stop the flow of water to your entire house. 2. Stains on Ceiling or Wall If you notice unaccounted for stains on a ceiling or wall, water may be the culprit of the discoloration. Wherever there is a stain, there's likely also damage to the material that's discolored. A water stain doesn't necessarily mean you have a leaky pipe, but it does show that there is unwanted water somewhere behind the stained surface. A stain on your uppermost ceiling could come from a leak in your roof, and a stain beneath a window probably means that the window's seal is letting water in. When a stain is located on a lower-level ceiling or an interior wall, however, a pipe is the most likely culprit. Determine where the leak is and then, have a professional plumber repair the leaky pipe that's hidden. Don't bother painting over the stain before the pipe is fixed, for the stain will soon reappear unless the underlying issue is addressed. 3. Mold Under a Sink If you notice mold in a cabinet that sits beneath one of your home's sinks, there's excess moisture in that cabinet. Mold can't grow without moisture. In this situation, first look for signs of mold elsewhere in the same room. The problem might not be only in the sink cabinet, and mold in multiple areas of a room could indicate a major moisture problem that goes beyond a localized leak. When mold is contained to just a single kitchen cabinet, though, there's a problem within the cabinet. The most probable issue in a sink cabinet is a leaky pipe, as a constant leak of water in a confined space like a cabinet will create excess moisture. When there's mold under a sink, you shouldn't try to deal with the issue yourself because mold spores can be harmful to your health. Instead, have a plumber fix the pipe and a mold specialist clean out any mold that is present. If you have a leaky pipe, contact the plumbing repair specialists at Preferred Mechanical Services.

Budgeting for Heating Costs in Your New Home

Fri, 08 Nov 2019 20:20:00 GMT

If you've recently moved to a new home, you may not know exactly how much you'll have to pay in heating costs over the winter. If you're being financially responsible and keeping to a budget, you'll want to know how much to budget per month for your heating expenses. Your heating expenses may vary based on several factors, so if possible, start with the costs from your previous home and adapt based on which factors have changed. Here are some factors that you should take into consideration when budgeting for heating costs. Size of House The first variable to take into account is the amount of space you'll keep warm this winter. If you used to live in a tiny apartment and now you've moved into a medium-sized house, the differences in heating expenses could be significant. The size of your home is also significant when compared to the size of your heating system. If the furnace is too large or too small, your heating costs may be slightly inflated because both of these situations can reduce the efficiency of your furnace. If you're unsure, have your contractor calculate whether your furnace is correctly sized. Region and Climate The area of the country will have a large effect on your heating and cooling costs as well. For instance, if you live in a very warm part of the country but recently moved several states north, you'll likely find yourself using your heating system much more. This may be balanced out to some degree by a lesser need for AC during the summer, though. Price of Electricity You'll also have to factor in how much you pay for the electricity that powers your heating system. One way to get around this variable (to some degree) is to have a solar-powered or geothermal HVAC system installed. An alternative energy source for your heating system could either greatly reduce or eliminate the need to use conventional electric power for heating. Gas furnaces also use less electricity , but have an added cost of the gas needed to run them. Type of Heating System Of course, the more efficient your system is, the less electricity you'll have to pay for. A heat pump, for instance, would give better value for your money than electric radiators. However, a heat pump typically comes with a backup heating system (an electrical heating coil) for colder weather, so you'd really only be saving money on heating when weather is above freezing. If you live in a cold climate where temperatures are often below freezing in winter, a dual system may offer optimal efficiency for your situation. A dual system can use a gas furnace during colder times and a heat pump when the weather is above freezing, rather than solely relying on your heat pump. Your Home's Building Envelop The more quickly heat escapes from your house, the more often your furnace will have to warm the area back up, and the more you'll be paying to heat the same space. Some ways you can improve your home's insulation include:

Adding blown-in insulation to walls
Increasing attic, wall, and floor insulation
Putting storm windows and insulating curtains on windows
Sealing up attic bypass holes and other holes in your building envelope (such as holes in floor under bathtub)

These tips can help reduce heat escape. You can also have an HVAC contractor come out to check for any vulnerable spots that could be wasting heat.
As you can see, when calculating your likely heating expenses, you'll need to adjust for several different variables. For more information on any of these points or to schedule heat pump or furnace maintenance or installation, get in touch with Preferred Mechanical Services today.

Reasons You Can't Get Enough Hot Water From Your Heater

Wed, 11 Sep 2019 17:00:00 GMT

Nothing will ruin your shower faster than a sudden blast of cold water because you've run out of hot water. That blast of cold water is sure to wake you up, but it's wholly unpleasant when you didn't plan on it. Below are some reasons you may have run out of hot water. Wrong-Sized Heater A common problem with new water heaters, or one that's new to you in case you just moved in, is that the heater isn't big enough for the demand. If you've chosen the heater yourself, you may not have considered usage. If the heater is in a home you've just moved into, perhaps the previous owners didn't have the same usage requirements. If you want a water heater with a tank, you can do some simple math to determine the size needed. Typical tasks that use hot water include the following:

Showering: 10 gallons

Shaving: 2 gallons

Washing clothes: 7 gallons

Washing dishes: 4 gallons by hand, 6 gallons by dishwasher

Imagine the peak usage time, and consider how many of the above activities you'll engage in during that time. For example, a family of three might take three showers in the morning and run the dishwasher. So, you'll need 36 gallons of hot water during peak usage time. That number tells you a 40-gallon tank should be sufficient. Sizing a tankless water heater involves trickier math. You may want to consult HVAC experts for this heater. Too Much Demand During Peak Usage Three showers and one instance of running the dishwasher shouldn't be too taxing for the average household. However, factors can affect peak water usage. For instance, you might have a family member who takes especially long, hot showers or who uses a bathtub. Or, perhaps you've recently converted to a highflow showerhead or built a wet bar. Again, you may have to switch to a higher-capacity water heater. You could also install a tankless water heater. Instead of heating a predetermined amount of water, a tankless system heats the water as needed. The system uses a heat exchanger, which transfers heat from electric coils or a gas-fired burner to the water. If you're not ready to upgrade your water heating system just yet, consider organizing a water usage chart. For instance, try running the dishwasher and clothes washer at night instead of when you also need to shower. Sediment in the Water Tank Even if the tank is technically big enough to meet the demands of peak water usage, sediment buildup can prevent the appliance from doing its job properly. Sediment can come from the water itself - it's simply the solid material that came in with the water. The tank can also accumulate rust and corrosion. When the sediment builds up at the bottom of the tank, it interferes with the heating elements. Therefore, they're unable to efficiently heat up the water. You may need to drain the tank several times to flush the sediment out. You can also call in the HVAC technicians to perform this task. Issues With Incoming Water The problem may not reside in your water heater but rather with the incoming water. One issue might be water pressure. The cold water that flows into the tank is supposed to force the hot water out to the relevant fixtures. If the pressure is insufficient, you won't get enough hot water. Problems for insufficient pressure vary and will almost certainly require professional diagnostics. One example of such a problem is a faulty dip tube, which is the pipe through which the cold water enters. This tube sometimes breaks or disconnects, which allows the cold water to enter from the top instead of the bottom. The hot water dilutes. You may need to replace this tube. A simpler issue might be that the incoming water is too cold. If the season is winter, and the decrease in hot water is sudden, consider raising the temperature on your thermostat. Don't suffer through a cold shower. Call the HVAC experts at Preferred Mechanical Services for help.

4 Signs You Have a Slab Leak

A slab leak occurs when a pipe underneath the foundation of your home begins to leak. The pipe may have corroded to the point that it leaks or the pipe may have burst. In some cases, you will be able to tell that you have a slab leak right away, because water will be puddling or pooling underneath your feet. In other cases, the water leak may be slow and it may not be obvious you have a leak. Knowing what the signs of a slab leak are can help you to identify a leak that may not be obvious.

1. Your Floor Has Hot Spots

If the water that is leaking out of your pipe is hot, you may notice that your floor has hot spots. Your feet may suddenly feel warmer when standing on one part of your floor compared to another part of your floor. If this is something you have not felt before and there is no explainable reason for the hot spots, you may need to consider the possibility that you have a slab leak.

2. Problems Are Developing With Your Floors

If a large amount of water is leaking from the pipe, your flooring may be soaked in water or you may see actual puddles on your flooring. However, if a leak is small, water may be affecting your flooring in different ways. If you have carpet in your home, you may notice a mildew-like scent as the padding gets wet. If you have vinyl or linoleum floors, you may start to see bubbling on the floor as the moisture damages the flooring material. If you have wood flooring, you may notice your flooring starts to warp or shift. If you have tile floors, you may notice your grout is crumbling or cracking.

3. Signs of Moisture Around the Exterior Base of Your Home

Water that is leaking from a pipe beneath the slab in your home does not always soak upward into your flooring. It may also spread outward. If the moisture is seeping outward, you may start to notice signs of moisture around the exterior base of your home. You may notice unexplainable puddles of water near the base of your home or signs that moisture is present, such as mildew growth, fungi growth, moss, or mud. If the leak has been going on for some time, you may notice the foundation of your home beginning to crack or problems with your siding material, such as rotted wood, efflorescence on bricks, or flaking on stucco.

4. Your Water Usage Has Unexpectedly Increased

If you have a water leak, your water usage may increase. In most cases, you will notice an increase in your water usage once you look at your water bill. If your water bill is higher than it normally is, and there is no reason for the increase, there is a strong probability that you have a water leak somewhere in or below your home. Most homes have water meters on them, which may help you to determine if you have a leak. Turn off all of the fixtures in your home that use water and do not run any appliances that use water. Then look at your water meter. If it is still moving despite no fixtures or appliances using water, you have a water leak, such as a slab leak. If suspect you have a slab leak, you will want to call in a professional to determine if do indeed have a leak and to make the needed repairs.

3 Substances That Can Clog Indoor Air Filters Fast

Wed, 19 Jun 2019 03:26:00 GMT

During the summer months, you rely on your HVAC system to keep your indoor air cool and dehumidified. Unfortunately, when indoor air filters clog, your system might run less efficiently, use up to 15% more energy , and be prone to issues like frozen-over evaporator coils - which can completely halt your system. However, by avoiding certain activities indoors, you can help to make your filters last and operate more efficiently. Here are three substances that can clog indoor HVAC filters fast and how to prevent problems.

1. Pet Hair and Dander

Your furry family members may make your house feel like a home, but unfortunately, they may continuously shed hair and dander that gets sucked up by your home's indoor air returns. Pet dander is composed of microscopic skin flakes, and many varieties of pet hair are light enough to float through the air and become trapped by particulate filters. While filters are helpful in preventing these potential allergens from continuing to remain airborne, they can also significantly reduce the lifespan of your air filter, impacting airflow. Over time, you might notice that your air conditioner seems to take longer to cool your home as not as much warm air makes its way through the filter and over those cooling coils. In fact, while most suburban homeowners only to replace their indoor air filters once a quarter, or every three months, homes with even one cat or dog should have filter replacements at least every two months , or as often as the filters fill up with pet hair. In addition to switching out your air filters frequently, consider having your pet professionally groomed on a regular basis to reduce the amount of shedding that takes place in your home. Avoid activities like brushing your dog or cat indoors, as this action can release dander and hair into the air, contributing to clogs.

2. Cooking Grease

Cooking at home is an ideal way to save money and eat nutritiously, but unfortunately, cooking fumes are another big cause of clogged HVAC filters. In fact, indoor air can become as much as five times as polluted as outdoor air because of indoor cooking, making it difficult to keep air filters clean and functional. As you cook, microscopic food and grease particles can become airborne, especially if you don't use a fume hood over your range. When these droplets go into your HVAC system, they can make the surface sticky, which makes filters accumulate other particulates like dust. If you cook at home frequently, be very vigilant about checking and replacing your HVAC filters. Keep extra filters on hand, and consider alternate, outdoor cooking methods to mitigate indoor air pollution. For example, consider grilling outdoors a few times a week or roasting things in your oven instead of deep-fat frying to protect your indoor air quality.

3. Fine Construction Debris

Home updates can also be incredibly hard on indoor air filters, especially if a lot of sanding, woodworking, and painting takes place. Fine sawdust can become airborne as soon as the process begins, and professionals who use high-end paint sprayers can unintentionally clog all of the HVAC filters in your home in seconds as wet paint droplets gravitate towards air returns. If you plan to renovate, protect your HVAC system by turning off your air conditioner and covering air filters and returns. When the project is over, you can uncover these areas after the house has aired out naturally. Because clogged filters can eventually lead to dust and grime buildup on your internal HVAC components, schedule a preventative system inspection at the start of each season, including summer.

How Rooftop HVAC Units Can Save Your Business Money

Fri, 19 Apr 2019 16:30:00 GMT

A heating, ventilation, and air conditioning (HVAC) unit is a business necessity. However, you don't have to spend most of your business budget heating and cooling your premises. Opt for rooftop HVAC systems and enjoy the financial benefits below.

Reduced Need for Soundproofing

Most workers, particularly those whose tasks require focus and concentration, are more productive in quiet places than in noisy places. Rooftop HVACs can help you out here because, with proper installation, they are quieter than indoor HVACs. Newer HVAC units are quieter than older units, but rooftop units are more silent since they sit outside and out of earshot.

The cost to soundproof an average room is over a thousand dollars . Imagine how much you would spend to soundproof a sizable commercial building with multiple offices. Fortunately, professional installation of a rooftop HVACs can save you from the soundproofing budget.

Increased Safety and Security

HVAC units that sit on the ground are at risk of theft and damage. Thieves target HVAC units for their valuable metals, specifically the copper. Most HVAC systems use copper for refrigerant lines because of the amazing conductivity of the metal. Most property owners or managers will agree that HVAC units that sit on the ground are easier targets for thieves than rooftop units.

As for damage, you have to worry about two things as far as ground HVAC units are concerned. First, truants can vandalize the ground units more easily than the rooftop systems and necessitate costly repairs.

Secondly, the ground units are more exposed to debris such as dirt and dust, which clog different parts of the unit and lead to frequent breakdowns and repairs. Don't forget that clogged HVAC systems tend to overheat, and overheated HVACs break down easily. Rooftop units tend to stay clean for long and thus don't suffer the consequences of clogged parts frequently.

Good Space Utilization

Commercial real estate space doesn't come cheap whether for purchase or lease. Moreover, commercial space in highly sought after areas command higher rates than other areas. As such, each square foot of space is important, don't waste any. Since you can put an HVAC unit on the roof, you can use the ground space for other things that you can't do on the roof.

Superb Energy Efficiency

Every business manager wants to increase their revenues and decrease their operational costs. Since HVAC energy consumption is a major expense, you can reduce your business overheads significantly if you can reduce your heating and cooling costs.

One way to decrease HVAC energy costs is to choose rooftop systems. Many of these systems come with energy saving features and controls that lead to overall energy efficiency. For example, some rooftop units (under some conditions) use outside air to cool the building and save on energy costs.

Increased Versatility

Lastly, rooftop HVAC systems can also save you money when the time comes when you need to expand or decrease your heating and cooling needs. For example, when you have renovated your property, increased some square footage, and want more heating and cooling.

Another case is when you have converted some part of the building to a different purpose that doesn't require heating and cooling. In both cases, a rooftop unit will save you money because these systems are modular and you can easily expand or decrease their productivity to match the new heating and cooling demands.

Talk to Preferred Mechanical Services if you want to install or upgrade your commercial HVAC system. We will work with you to size and install an excellent system that will meet your needs. Contact us for a quote, and we will get back to you as soon as possible.

3 Things to Know About ECM Furnaces

Fri, 22 Feb 2019 16:00:00 GMT

For many decades, furnace technology remained relatively stagnant, with few significant chances in the ways that residential furnaces worked. In recent years, however, the HVAC industry has seen numerous advances. While new technology has vastly improved potential furnace efficiency, it has also left many consumers confused about their home heating options. ECM furnaces rank among the most exciting advances in furnace technology. Unfortunately, few homeowners understand the benefits of ECM furnaces, let alone how they work. If you seek to broaden your knowledge of today's HVAC technology, keep reading. This article outlines three key things to know about ECM furnaces. 1. ECM Furnaces Differ Primarily in How They Distribute Heated Air In most regards, an ECM furnace functions much like a conventional furnace. The burner ignites a mixture of gas and air inside of the combustion chamber, which produces heat and exhaust. These hot combustion gases then flow into the heat exchanger, which facilitates the transfer of heat to the air of your home. An ECM furnace differs in how it distributes this heated air. A normal furnace uses a blower fan with two settings: on and off. Either the fan blows at full speed, or it does not blow at all. An ECM furnace, by contrast, can operate at virtually any speed in between the two extremes. This ability provides an extra degree of versatility and efficiency when it comes to distributing heated air. 2. ECM Furnace Fans Use a Different Type of Motor The blower fans found in conventional furnaces use a type of motor known as a permanent split capacitor, or PSC for short. As discussed above, a PSC motor can only operate in two modes, on and off. PSC motors, which run on alternating current, do not contain the internal controls necessary for varying the rotation speed of the motor. An ECM furnace, by contrast, contains an electronically commutated motor - hence the acronym ECM. Several different types of ECM motors exist, known alternately as ECM 2.3, ECM 2.5 and ECM 3.0. These motor types differ primarily in terms of their programming options, while sharing the same basic technological model. Unlike PSCs, ECM technology uses direct current. Generally speaking, direct current is inherently more efficient than alternating current. An ECM 2.3 motor boasts overall efficiency of around 80 percent . A PSC motor, by contrast, seldom exceeds 60 percent efficiency. In addition, direct current produces cooler operating temperatures, which limits motor wear and tear. 3. ECM Furnaces Increase Home Comfort Levels The more efficient nature of an ECM motor means that it will lower your operating costs as time goes on. Yet an ECM furnace delivers equally impressive benefits when it comes to your air quality and indoor comfort. The ability to regulate fan speed allows your blower system to optimize how it conditions and distributes heated air. For instance, ECM furnaces usually run their blower fan at 50 percent speed for approximately the first seven minutes of operation. This slower fan speed gives your system more time to circulate air inside of your home. A conventional furnace, operating at 100 percent fan speed, often raises your indoor temperature too quickly. As a result, indoor air quality often suffers. By running its blower at a slower speed, an ECM furnace gives indoor air more time to pass through your filtration system to remove potential allergens. Likewise, the slower circulation speed gives your system the time it needs to ensure optimal humidity levels. Ultimately, an ECM furnace saves money in operating costs and promotes better indoor comfort.

4 Ways a New AC Unit Is More Eco-Friendly

Mon, 29 Oct 2018 01:50:00 GMT

You may have heard that you should replace your old AC unit, but if you're environmentally minded you might feel it's more responsible to use up the old one until it falls apart first. However, you can actually make your day-to-day environmental footprint smaller if you invest in a new unit. Here's how.

1. Efficient Cooling Ability

Newer AC systems aren't the energy hogs they were a decade or two ago. In fact, if you have an older unit, you may have very outdated energy costs. Just buying any new unit could help reduce your energy costs significantly by using newer cooling technology.

This change in efficiency is partly because the standards in the U.S. have changed so that, in most states, all new central AC units are rated at SEER 14 (seasonal energy efficiency rating) or above. To give you an idea of what that means for your energy use, a SEER 15 unit can save you about 33% overall compared to an old unit rated SEER 10. And a SEER 20 unit can save you 50% .

These new technologies and efficiency standards aren't just groundbreaking for your wallet. They can also make a real difference in your carbon footprint while still letting you live a comfortably cooled life.

2. Correct Size

Your house may have a correctly sized unit already. But if the house size wasn't calculated correctly, or if the house has had additions built recently, your AC system could be too large or too small. If your unit turns on and off frequently or seems to be always on, or if your house doesn't seem to get cool in the summer, this could be your situation.

A too-small unit is inefficient (as well as ineffective) because it has to work harder than it was designed to. It may run constantly, use more energy, and wear out faster than intended, meaning more AC components end up in the landfill. A too-large unit, on the other hand, is wasted on your small home; it can wear out quickly, too, due to constant on-off cycling.

Replace a too-large or too-small unit to help you avoid these problems and avoid wasting energy and wearing out your system too fast. Be sure to have an expert contractor calculate the correct unit size for you based on your current house size, your climate, and other relevant factors.

3. Alternative Energy Source

If you're looking into going off-grid or even just reducing your dependence on fossil fuels by installing a few solar-powered items around your home, a solar-powered AC unit may be right for you. In order to solarpower your AC, you can either buy a package that comes with a unit and solar panels, or you can simply buy solar panels separately and hire an electrician.

Either way, you will need a super-efficient AC in order to feasibly go off-grid. The more efficient your unit is, the more likely it is that you can power it reliably with just a few solar panels.

4. Eco-Friendly Coolant

If you've noticed the prices of R-22 refrigerant lately, you may have heard it's no longer the coolant of choice (it becomes illegal at the beginning of 2020). Newer AC units use an alternate refrigerant, typically R-410A, which is better for the environment.

That's all well and good, but you can't put the alternate refrigerant in a system designed for R-22 or it will malfunction. So in order to reap the benefits of switching to a more ozone-friendly refrigerant, you'll need to buy a new AC unit. Fortunately for you, the standard now is to design and build all the commonly used AC units to be compatible with R-410A, so you don't have to look far to find a usable model.

These four points show how buying a new AC unit gives you the opportunity to make your life more ecofriendly while still staying comfortable during the summer. If you need help finding the right size air conditioner, understanding the technical specifications, or replacing your old unit with the new one, get in touch with Preferred Mechanical Services today.

Spotting and Repairing Leaks in Your Garbage Disposal

Tue, 28 Aug 2018 14:08:00 GMT

Food particles that are stuck to plates, pans, and silverware can find their way into your sink's drain. These food items can congeal in your drainpipes, causing serious clogs that can compromise the function of your plumbing system.

A garbage disposal can help you safely process any food particles that find their way into your drains. Food passes through the disposal, where it is ground into pieces small enough to pass safely through your plumbing.

While a functional garbage disposal can be a beneficial tool, a leaking garbage disposal can be a serious cause for concern. Look for leaks regularly to keep your garbage disposal working properly.

Check the Sink Flange

One of the most common sources of a leak in your garbage disposal system is a faulty sink flange. The sink flange connects the top of the garbage disposal to the drain in your kitchen sink. The flange needs to sit flush against the drain in order to allow water and food particles to pass from the sink into the garbage disposal.

Wipe down the exterior surface of your garbage disposal and any exposed pipes underneath your sink. Place a stopper in the sink drain, then fill the sink with a few inches of water. If the sink flange is working properly, no water should pass through the drain and into the cabinet below.

If you see evidence of moisture collecting on the exterior surfaces of your disposal while the drain stopper is in place, your garbage disposal has a bad sink flange. Replacing the flange will prevent water waste and help you avoid a clogged sink in the future.

Check the Dishwasher Hose

A dishwasher can be a time-saving appliance to add to your kitchen. Just like you don't want food particles going down the drain of your kitchen sink, you don't want any food particles washed off your dishware during a wash cycle finding their way into the drain of your dishwasher.

A garbage disposal can help process the water and particulate matter that drains from your dishwasher. A flexible plastic hose connects the dishwasher to the garbage disposal. Over time, this hose can become cracked or kinked. A deteriorating hose will result in leaks that may appear to be coming from your garbage disposal.

Wipe down all the pipes and hoses connected to your garbage disposal before running a load of dishes through the dishwasher. Look at the dishwasher hose during the appliance's cycle. Any moisture collecting on the hose indicates that you will need to replace the dishwasher hose to prevent dangerous leaks from compromising your garbage disposal.

Check the Drain Pipe

Another area where your garbage disposal might start to leak is the connection point between the drainpipe and the disposal unit. The drainpipe funnels all processed waste from the disposal unit into your home's main plumbing system.

A secure seal between the drainpipe and the garbage disposal is required to keep all waste within the pipe during removal. You can spot a drainpipe leak by conducting a visual inspection of the connection point while running your garbage disposal. Water beading around the seal indicates an improper connection.

Plumber's tape or another sealant can be used to restore the watertight connection between the drainpipe and your garbage disposal unit to prevent water leaks from becoming a serious problem in the future.

Monitor your garbage disposal for leaks if you want to ensure your plumbing is protected against clogs caused by food particles. If these basic troubleshooting steps don't solve the problem, contact Preferred Mechanical Services for more information on spotting and repairing a leaking garbage disposal in your home.

Role of the Thermostatic Expansion Valve in a Commercial AC

Thu, 28 Jun 2018 03:14:00 GMT

All air conditioners contain a type of component known generally as throttling devices. These devices act to regulate both the refrigerant's pressure and its temperature. The most common variety of throttling device used in commercial air conditioning systems is known as the thermostatic expansion valve.

Unfortunately, the general lack of understanding about the function and role of the thermostatic expansion valve means that it is often the source of problems as time goes on. If you would like to keep your AC running strong by learning more about this key component, read on. This article will offer a useful introduction to thermostatic expansion valves.

What It Is

As noted above, thermostatic expansion are the type of throttling device most commonly found on commercial air conditioning systems. Residential systems, on the other hand, often utilize the relatively simpler device known as a capillary tube. Yet a capillary tube simply wouldn't be able to handle the complex and ever-changing needs of a commercial system.

A commercial HVAC setup also has to regularly deal with much greater output demands. This fact is especially true of the air conditioning systems used in restaurants since the heat of a kitchen will require that the system work much harder and for longer periods of time. In order to cope with such a demanding scenario, a more sophisticated throttling device is necessary.

The key distinction between a capillary tube and a thermostatic expansion valve is that an expansion valve is capable of altering the refrigerant's rate of flow. A capillary tube, on the other hand, only permits a fixed rate of flow, no matter what the particular demands on the system may be.

A thermostatic expansion valve is designed to respond to the temperature of the unit's evaporator coil. A special thermal bulb will read the conditions and cause the valve to open wider as the temperature rises. This function permits a greater amount of refrigerant to enter the coil, thereby enabling it to better meet a given cooling task.

How It Regulates the Evaporator Coil

As you can likely gather from the discussion above, the thermostatic expansion valve plays a key role in optimizing the efficiency of the evaporator coil. If the flow of refrigerant merely remained static, the system would struggle to meet the demands associated with higher cooling loads.

In case you don't know, cooling load is a useful term used to refer to the difference between the actual temperature and the desired temperature. Obviously, as cooling load increases, more refrigerant is needed to ensure ideal results within an acceptable time frame. Yet the thermostatic expansion valve plays an equally important role when cooling load is low.

By reducing the refrigerant flow in such situations, the thermostatic expansion valve keeps the system from expending unnecessary amounts of energy on relatively simple cooling tasks. It also has a positive impact on efficiency by lowering the refrigerant's pressure.

The lower the pressure of the refrigerant, the more readily it will be able to absorb heat inside of the evaporator coil. In the process, it will change more quickly back into its gaseous form, thus speeding up the return rate from the evaporator coil to the compressor. This action promotes a quicker overall cycling of the refrigerant.

Bottom Line

You don't have to be a professional HVAC technician to understand the vital role that thermostatic expansion valve plays in a commercial air conditioner. And the more you learn about how this key component works, the more likely you may be to avoid some of the common problems it faces.

When the time comes for maintenance and repairs, however, this is a task best left to the pros. For more information about keeping your thermostatic expansion valve in peak condition, contact the commercial AC experts at Preferred Mechanical Services .
