How Regulation Changes to Air Conditioner Refrigerant Affect Birmingham Homeowners

Thursday, March 28th, 2019

Less than a year remains before a law banning the production of a common air conditioner refrigerant goes into effect. As part of Sections 601-607 of the Clean Air Act, manufacturers aren’t allowed to make Freon, also known as HCFC-22 or R-22, and must phase it out of use completely by January 1, 2020.

What does this mean for Birmingham homeowners with HVAC units that rely on Freon air conditioner refrigerant? Below we help clear the air about the upcoming R-22 ban and ways to stay in compliance with the new regulations.

Air Conditioner Refrigerant 2020 Regulations

For decades, residential air conditioners used R-22 as the main air conditioner refrigerant chemical. Studies found HCFCs (hydrochlorofluorocarbons), the chemicals refrigerators and air conditioners use to cool, contribute to ozone depletion and climate change.

The Environmental Protection Agency issued a mandate phasing out the production of R-22 by January 1, 2020.

What the Air Conditioner Refrigerant Regulations Mean for Homeowners

The good news for Birmingham homeowners? Air conditioning systems made after 2010 no longer rely on R-22. Instead, most new units use a more environmentally-friendly air conditioner refrigerant called R-410A. Also called Puron, it’s an HCFC harmless to the ozone.

If you had an HVAC technician install a new air conditioner sometime over the past decade, it’s possible it’s compliant.

However, it’s still best to look for your air conditioner’s refrigerant type on your condenser’s nameplate, consult your user’s manual, or check with an HVAC technician just to be safe. Have you scheduled a tune-up for your air conditioner yet? Now’s a great time. You can verify refrigerant compliance as well as benefit from maintenance services. 

If you cool your home with a pre-2010 AC unit that uses R-22, you have a couple options:

Option #1: Retrofit Your Current AC System

You’re not required under the mandate to buy a new air conditioner. However, you cannot drain your unit of R-22 and switch to an ozone-friendly air conditioner refrigerant.

Different refrigerants operate at different pressure levels and need different components to run. The retrofit process requires an HVAC technician to replace parts of your system to coincide with a new environmentally friendly refrigerant. Skipping this step may lead to system failure, in which case you have to purchase a new system anyway.

However, if your older AC unit’s coils are compatible with R-410A refrigerant, it’s possible for an HVAC professional to replace the condenser without modifying other components throughout your house. While costly, it keeps your current system working and in compliance with the mandate.

Option #2: Replace Your Older AC Unit

Retrofitting older air conditioners often costs as much or more than a new unit installation. Therefore, many homeowners replace their AC unit with a new system designed to use R-410A or other permitted coolants.

The average lifespan of an HVAC system is 15 years. A new unit ensures greater long-term savings through increased efficiency. Plus, system replacement eliminates the R-22 replacement cost and higher energy bills for the next several years.

Count on Douglas Cooling & Heating to Keep You Up-to-Date with Air Conditioner Refrigerant Rules

In conclusion, proper installation, servicing and air conditioner refrigerant replacement requires special training to prevent leaks of harmful chemicals. Contact Douglas Cooling & Heating for professional advice about the type of air conditioner refrigerant in your HVAC unit or the best solution for the older air conditioner unit in your Birmingham home.

Better Sleep with HVAC Service in Birmingham

Tuesday, March 26th, 2019

Improve your sleep experience when you hire Douglas Cooling & Heating to perform your HVAC service in Birmingham! Whether your home is too warm, too dry, too humid or has poor air circulation, HVAC service helps.

Stop tossing and turning all night and wake up refreshed in the morning. Try any of these HVAC services and solutions designed to help you maximize comfort levels and get a peaceful night’s sleep.

Use HVAC Service & Products to Control Humidity

Optimize your home’s humidity level for ideal sleep conditions. Too little humidity leads to itchy, dry skin, which wakes you up. Too much leaves you uncomfortable and clammy. You won’t be able to relax, and you may not be able to breathe well.

Besides, thick, sticky air attracts insects and promotes mold and dust mite growth. That’s truly a nightmare for anyone in your home who suffers from allergies, asthma, or other respiratory issues.

Eliminate this problem when you install a whole-home humidifier or dehumidifier. In Birmingham, we have unique challenges with humidity at different times of the year. Ask your Douglas Cooling & Heating consultant for a customized plan based on your needs.

Wi-Fi Thermostats

As you approach sleep, your body temperature decreases. You need your bedroom’s temperature to do the same. For this reason, the National Sleep Foundation recommends setting your room’s overnight temperature to between 60 and 67 degrees Fahrenheit. Set it warmer or cooler and potentially negatively affect the quality of your REM sleep.

Install a programmable thermostat to make temperature control an automatic part of your bedtime routine. A programmable thermostat allows you to set the temperature to fall automatically every night just before bedtime.

Fans and Zoned Air Conditioning Systems

Ceiling fans are a great solution to help combat the higher energy costs of turning down the temperature a few degrees to promote restful sleep in the summer. The continuous air circulation they offer results in a cool and comfortable night’s sleep with a downdraft.

The hidden benefit is the soothing white noise helps many fall asleep. Zoned air conditioning systems are another option. They allow you to set different temperatures in different rooms or sections of the house.

This promotes targeted air circulation and temperature regulation in your home. By dropping the temperature in just your bedroom, you have the option of keeping it comfortable without spending money to cool the rest of the house at night.

Basic HVAC Service: Air Conditioning Tune-Up

No matter your home’s heating and cooling system setup, your HVAC system should function as efficiently as possible to help you get high-quality rest each night. It starts when you hire a licensed expert for HVAC services such as a heat pump or an air conditioner tune-up.

We recommend one every spring before temperatures climb. This makes it easier for your system to maintain your preferred temperature, humidity levels and air circulation. It also helps reduce your energy bills — great peace of mind as you drift off to sleep!

Trust Douglas Cooling & Heating for All Your HVAC Service Needs

The team at Douglas Cooling & Heating is happy to provide HVAC services to keep your system running smoothly and your family resting easily.

Air Conditioning History: Margaret Ingels

Tuesday, March 12th, 2019

Air conditioning history is relatively short. It has only existed since the early 20th century, in part due to engineering pioneers who developed temperature control technology. At Douglas Cooling & Heating, we are big fans of air conditioning history, as you can imagine.

Did you know without the contributions of pioneer Margaret Ingels, we wouldn’t have air humidity measurement tools or have come nearly as far in air filtration technology? This Women’s History Month, we celebrate Ingels and her many contributions to air conditioning history.

Early Life and Education

Ingels was born in 1892 in Paris, Kentucky, and had an interest in science from the start. As a young girl, she watched moisture collect on glass and became curious about condensation. This curiosity eventually led to a successful career in air conditioning.

She enrolled at the University of Kentucky with intentions to pursue architecture. Because the school didn’t have such a degree program yet, a dean persuaded her to study mechanical engineering instead. She thrived and served as secretary for several engineering groups before she graduated with honors.

In 1916 she became the first woman to graduate from the school’s College of Mechanical Engineering. She was the first woman at the school to earn an engineering degree and only the second female engineering graduate in the United States.

Career

After college, Ingels worked in the traffic engineering department for the Chicago Telephone Company. She moved to Pittsburgh in 1917 to work for the Carrier Lyle Heating and Ventilation Corporation, where her interest in air conditioning began.

She received the Mechanical Engineering professional degree in 1920. The next year she joined the American Society of Heating and Ventilating Engineers research lab, where she studied air conditioning for six years.

In 1931, she returned to Carrier-Lyle, where she worked until retirement. Ingels helped develop the Anderson-Armspach dust determinator, which became the industry standard for air filtration, and the sling psychrometer, a relative air humidity measurement tool still used today.

Her career also included working in a U.S. Bureau of Mines laboratory to help create air cleanliness standards.

Industry Advocacy

Ingels’s contributions to air conditioning history weren’t limited to her work in laboratories. She also served as an advocate for the profession. From 1932 to 1952, she wrote more than 45 technical papers. She also traveled across the country to deliver more than 200 speeches to more than 12,000 people.

Her most well-known speech, “Petticoats and Slide Rules”, documented “the pioneer American women of the engineering field.” In it, she wrote female engineers had a responsibility to “widen the trails blazed for her — and more. She must build them into great highways for women engineers of the future to travel, free of prejudices and discrimination.”

Awards and Recognition in Air Conditioning History

Her advocacy and professional achievements earned Ingels several accolades throughout her lifetime. Along with 100 other American women, including Eleanor Roosevelt, she was selected to the 1940 Women’s Centennial Congress, which recognized females who had successful careers in fields not open to women a century earlier.

Her alma mater also awarded her an honorary law degree in 1957 and inducted her to the College of Engineering’s Hall of Distinction in 1993.

Ultraviolet Air Cleaners vs. Media Air Cleaners: What’s the HVAC Difference?

Thursday, March 7th, 2019

Before you improve the indoor air quality in your home, it’s best to understand the HVAC difference between an ultraviolet air cleaner or media air cleaner. Both keep unwanted contaminants out of your home’s air.

Both allow you to breathe easier and healthier air. But, each system works differently and has its own advantages. Below, we explore the similarities and differences between these two indoor air quality products.

Media Air Cleaners

Media air cleaners serve as a great first line of defense to improve your home’s indoor air quality. Essentially, they are highly effective air filters which trap tiny invisible air particles. These pollutants include dander, pollen, mold and dust. Media air cleaners are installed on a return duct line and prevent particulates from entering your home.

How Media Air Cleaners Work

A media air cleaner is a cabinet placed in the return air duct of the forced air system. As air passes through your HVAC system, the media air cleaner traps airborne particles within the filter media before they reach your indoor atmosphere.

The main HVAC difference between a media air cleaner and a standard air filter is size. Conventional air filters are an inch thick while media cleaners are 4 to 5 inches thick. This allows for more and better air filtration.

IAQ Advantages of Media Air Cleaners 

Here are ways a media air filter improves air quality in your home:

  • More effective than traditional filters: A media air cleaner provides up to 40 times more filtering media than a traditional 1-inch thick air filter.
  • Captures invisible particulates: As air flows through the cleaner, it traps tiny particles as small as 0.1 microns. To give you an idea of how small that is, consider the average thickness of a human hair is between 30 to 100 microns!
  • Captures pathogens: A media air cleaner captures up to 98 percent of airborne particles containing bacteria, mold spores, and viruses. These have the potential to cause dangerous and even deadly diseases in humans.

Ultraviolet Air Cleaners

The main HVAC difference between media air cleaners and ultraviolet media cleaners? One is a filter and one uses light to prevent harmful particles from entering your home’s air. Ultraviolet air cleaners live inside your HVAC system and kill any potentially harmful bacteria before it enters your living space. They do not rely on filters to remove airborne contaminants.

How Ultraviolet Air Cleaners Work

Ultraviolet air cleaners use state-of-the-art ultraviolet (UV) light technology to stop virus reproduction. This effectively prevents the spread of diseases or re-infection. Ultraviolet air cleaners often combine a UV lamp with a media air filter to remove harmful particles from your home’s air and kill germs and bacteria.

IAQ Advantages of HVAC UV light

UV air cleaners help purify your home’s air in the following ways:

  • Kills mold and bacteria: It’s almost impossible for air conditioners to stay dry from within. UV light significantly reduces microbes on the coils within your system. Also reduces the risk of mold and other bacteria from entering the rooms in your home.
  • Removes VOCs: UV lights lower the amount of VOCs in your home. Volatile organic compounds include both human-made and naturally occurring compounds. These range from acetone in furniture polish and wallpaper to benzene in paint and carpeting. VOCs have a direct effect on your home’s indoor air quality as well as your family’s health. This is especially true for those who suffer from allergies, asthma, respiratory illnesses or certain cardiac conditions.

The Benefits of Springtime Heating and Cooling Service in Birmingham

Tuesday, March 5th, 2019

Did you know right now is the best time of year to schedule heating and cooling service?

It’s true — to confirm it’s still in great shape for the long summer ahead, it’s a great idea to schedule an HVAC system tune-up for the spring. Below, we outline the many benefits of scheduling a routine springtime heating and cooling service appointment and inspection.

What Does Springtime Heating and Cooling Service Involve?

To verify everything is operating properly, a professional heating and cooling service call should include:

  • Check and test refrigerant levels for undetected leaks.
  • Ensure the condensate drain is clog-free and drains properly.
  • Measure airflow through the evaporator and cleaning coils.
  • Replace the air filter, check the blower and inspect the ductwork.
  • Test thermostat settings and sensors for proper operation.
  • Check electrical components for loose connections or corrosion.

Why Schedule Springtime Heating and Cooling Service?

The Environmental Protection Agency (EPA) recommends spring as the best time of the year for heating and cooling service. It ensures your home’s comfort in the heat of summer. Other advantages of getting a HVAC tune-up before summertime include:

Detect Potential Problems Early

If you already turned on your air conditioner for the spring and feel like it isn’t cooling the house off yet, you may have a problem with your unit. When your HVAC unit runs as it should, you feel cool air when your thermostat is set to cool almost immediately.

As part of a routine HVAC checkup, a technician tests your system for proper operation and, if needed, repairs the issue.

Maintain and Improve Your HVAC System’s Efficiency

Wait much longer and your HVAC unit is only going to continue to get dirtier — and much less efficient. Your heating and cooling service appointment ensures your coils are dirt and debris-free.

This way, your fan doesn’t work any harder than it needs to. This appointment also recalibrates the thermostat to prevent short cycling. Short cycling is when your unit turns on and off at the wrong time. This reduces your home’s comfort levels and puts more stress on your HVAC system.

Improve Your Home’s Air Quality

Air duct cleaning removes much of the dirt and debris that lodge in your home’s ductwork during the winter. These particles have the potential to recirculate up to five to seven times a day when your air conditioner kicks into high gear this summer.

Avoid unnecessary airborne debris and an uptick in respiratory illness with spring maintenance.

Beat the Summer Rush

It is more convenient to have your unit serviced before the summer rush. Once the temperature rises, demand for heating and cooling services increases in Birmingham. Schedule a maintenance appointment in the spring to ensure your house is ready for hot and humid Alabama summers.

Call Douglas Cooling & Heating for Springtime Heating and Cooling Service

Make Smart Thermostats Part of Your Spring Break Plans

Thursday, February 21st, 2019

Spring break will be here before you know it! With the kids off school, many families choose to leave Birmingham for a vacation. When you think of trip preparations, you may overlook a thermostat adjustment for your absence. It can be a costly one! If you have a spring break trip planned, don’t forget to use programmable and smart thermostats to your advantage when away from home!

Programmable and Smart Thermostats

Programmable and smart thermostats are any homeowner’s top tool for saving money on heating and cooling costs! These tools make adjusting heating and cooling system usage a breeze while they cut unnecessary energy use for lower bills.

A smart thermostat builds upon the capabilities of programmable models – instead of preprogramming temperature schedules, the smart thermostat does the work for you!

After a couple weeks of manual program adjustments, smart thermostats learn the habits and preferences of your household. Then they automatically make temperature adjustments based on what is most efficient at the time, without sacrificing your comfort.

Using Smart Thermostats for Spring Break Savings

Setting your thermostat back is a quick way to save up to 10 percent on annual heating and cooling costs! While your family is away for spring break and other trips throughout the year, set back your thermostat for effortless savings.

Achieve energy savings with a reduction of 7-10 degrees for periods of eight or more hours. While you’re on vacation is the perfect time to do so, as no one is home in need of heating or cooling. If you have pets staying home, be mindful of their needs. Consult with your vet for breed-appropriate needs.

If your home is equipped with a programmable thermostat, switch the thermostat to vacation mode or hold before leaving. Doing so pauses your normal temperature schedules, allowing you to set back your thermostat several degrees for the entire period you are away.

During colder months, set your thermostat to no less than 50 degrees to cut heating use while protecting your home from potential damage due to cold weather, such as frozen pipes.

Smart thermostats are a little different, as they do the setting work for you. Your smart thermostat detects your home is unoccupied and will do an automatic setback. It raises or lowers the temperature for optimal energy efficiency depending on the season.

Using your smart thermostat’s geofencing technology, your thermostat detects when you are approaching home at the end of your trip. Geofencing tells your thermostat you are returning home so the smart thermostat adjusts temperatures to make your home comfortable when you walk back in the door.

Wi-Fi Connectivity with Smart Thermostats

Smart thermostats are WiFi connected, allowing you to access it while you’re away from home. Using the smart thermostat’s app on your smartphone or tablet, you are able to monitor temperature settings from pretty much anywhere.

Also, smart thermostats alert you if issues are detected which require attention when you’re gone. This is often helpful for everything from filter changes to malfunctions or spikes in activity.

Douglas Cooling & Heating Happily Recommends Smart Thermostats Best for Your HVAC System

Douglas Cooling & Heating connects homeowners with money-saving solutions like smart thermostats for improved energy efficiency whether you’re home or not! Contact us today to learn more about how smart thermostats and programmable models help you lower utility costs over spring break and throughout the year. We strongly encourage a thermostat consultation. Certain smart thermostats work better with specific heating and air systems.

Pollution in Your Birmingham Home’s HVAC System

Tuesday, February 19th, 2019

An HVAC system is exposed to high levels of airborne contaminants as air passes through the equipment. When these contaminants settle within the system, they diminish indoor air quality in your Birmingham, AL home or business. Additionally, these pollutants hurt the equipment’s performance. Learn more about the contaminants in your system and how to prevent damage.

Contaminants in HVAC Systems

According to the Environmental Protection Agency, the air indoors can be two to five times more polluted than outdoor air. An HVAC system is exposed to this pollution as air passes through the equipment during the heating and cooling processes.

HVAC systems may be exposed to the following contaminants, depending on factors specific to each home or business:

  • Combustion byproducts from fuel-burning appliances
  • Tobacco smoke
  • Pet dander and hair
  • Mold and mildew
  • Dust
  • Dirt
  • Pollen
  • Bacteria
  • Viruses and
  • Carpet fibers.

As air circulates through the system, these contaminants settle. They’re found in ductwork, in equipment cabinets and on components. Over time, contaminants build up where they impact system performance.

These pollutants reduce performance, and also sometimes cause damage to components. Ultimately, this damage often necessitates an HVAC repair or component replacement.

Prevent Harm to Your HVAC System from Pollution

Pollution exposure is inevitable due to the nature of the work an HVAC system performs. Fortunately, there are measures to reduce the amount of pollution in your system. Limit the system’s contaminant exposure, and also reduce the risk of damage and performance problems.

Douglas Cooling & Heating’ NATE-certified technicians professionally perform and install solutions for better indoor air quality, as well as improved system performance.

Preventative maintenance tune-ups

Preventative maintenance tune-ups go a long way toward undoing the damage of contaminant exposure. During a preventative maintenance tune-up, a NATE-certified heating and cooling technician cleans debris from HVAC system components.

He or she removes buildup from equipment cabinets and parts. This maintenance task eliminates large amounts of contaminants in the system. Additionally, it prevents them from HVAC system circulation.

High-efficiency air filters

An excellent defense against contaminants in your HVAC system is high-efficiency air filters. Furnace filters with MERV ratings of 8 or higher remove higher amounts of smaller contaminant particles versus low-rated filters.

This prevents the entrance of more pollution and potential damage. Change your furnace filters on a regular basis to ensure the filter provides the level of defense needed.

Duct cleaning

As pollution circulates through an HVAC system, it often settles within the duct system. Ductwork harbors pollutant accumulation, where these contaminants circulate into the system. Duct and vent cleaning removes pollution from within the duct system.

This improves indoor air quality and prevents damage to sensitive system components. Additionally, it dramatically improves your indoor air quality.

Air cleaners

When you install a media air cleaner with your HVAC system, it will keep more contaminants out of your indoor air supply. By extension, it also keeps them from your HVAC equipment.

Media air cleaners use high-efficiency air filters to remove more harmful contaminants from your indoor air supply. If a loved one lives with respiratory illness such as allergies, asthma or COPD, these reduce many of the triggers.

Dehumidifiers

Dehumidifiers work with your HVAC system to eliminate excess moisture. Too much poses a threat to your HVAC equipment, as well as your indoor air quality. A dehumidifier balances relative humidity levels throughout the year.

Dehumidifiers also maintain controlled environments and prevent mold, mildew and dust mite growth within your HVAC system.

Douglas Cooling & Heating Cares About Your Comfort and Safety – Let Us Make Your HVAC System a Partner in Your Health

Rid your HVAC system of harmful contaminants for improved heating and cooling performance. A healthy HVAC system keeps your Birmingham, AL home or business more comfortable throughout the year. So contact Douglas Cooling & Heating today for the solutions you need for a cleaner HVAC system.

Birmingham, AL HVAC 101: Heating and Air Blower Fans

Tuesday, February 12th, 2019

HVAC systems consist of many components, each playing an important role in the heating process. Whether your Birmingham, AL area home utilizes a furnace or a heat pump for wintertime warmth, a blower fan is the component responsible for moving heat to living areas, keeping your family cozy.

Douglas Cooling & Heating provides expert HVAC services in Birmingham to care for all heating system components. Below, we’ll share more information about your heating system’s blower fan to better understand its importance to the heating process. In addition, we’ll cover how to know if yours requires service.

What Is an HVAC Blower Fan?

The HVAC blower fan, also called a blower motor, is the system component responsible for circulating heated air through the home’s ductwork. The blower fan also works during the cooling process to circulate chilled air throughout the home.

Blower motors can be single-speed or variable-speed.

  • Single-speed blower motors work at one speed. They operate at full energy capacity to blow air through the ductwork.
  • Variable-speed blower motors operate at different speeds based on the comfort needs of the home. This type of blower motor uses less energy and delivers better temperature and humidity control.

HVAC Blower Fan Trouble Signs

If your HVAC system’s blower fan isn’t operating correctly, comfort control issues result. Solving blower motor problems often requires the assistance of a qualified HVAC technician. Below are some signs your blower fan needs service from an HVAC professional.

Heating system runs constantly without creating comfortable indoor temperatures

A furnace that runs around the clock without keeping indoor living areas at a comfortable temperature needs service. While the furnace or heat pump is creating or transferring heat to warm the air, this warm air is not being sent into your home.

A blower motor malfunction is likely the source of this issue. Loose, worn out belts or bad bearings may prevent the blower fan from operating correctly. Another example is the blower fan may not be receiving power. This may be due to a flipped breaker or a short in the component’s electrical wiring.

Loud noises when furnace starts, stops, or runs

Faulty blower fan components can be responsible for sudden, unsettling sounds when your furnace or air handler runs.

Squeals

Loose blower motor belts often cause a squeal when the heating system runs. Unlubricated shaft bearings can also cause a similar noise. Our HVAC technicians solve the issue when they tighten or replace belts and lubricate bearings.

Scrapes or Clanks

These sounds of metal against metal result from a loose blower fan wheel. When the blower fan is loose, it strikes the housing casing. This causes the scraping sound during heating cycle operation. If you hear this sound, turn off the heating system right away and contact us for help. Our HVAC technicians inspect the system for damage and replace broken components.

Screeches and Rattles

Sounds at the start of a heating cycle are often related to the bearings within the blower fan. If the bearings are not lubricated regularly, the blower fan may seize and cause damage to the system as well as strange noises.

Your heating system’s blower fan is key for the distribution of warm air throughout your Birmingham, AL area home.  Regular preventative maintenance and tune ups can keep your blower motor in good working order. Service prevents performance issues such as efficiency and comfort loss, plus potential damage.

For the most convenience and value, check out our Maintenance Agreements. We offer three levels to fit every budget.

Douglas Cooling & Heating in Birmingham is Your HVAC Partner

Protect your HVAC system’s blower fan with maintenance and repair from Douglas Service. If you experience any of the issues mentioned above, contact us now and schedule a service call. If you find you need to replace, we offer free estimates and finance options.

HVAC 101: Air Handlers and Heat Pumps in Birmingham, AL Homes

Thursday, February 7th, 2019

Many Birmingham, AL homes choose heat pumps for year-round indoor comfort. An excellent, low-energy choice for the Birmingham area, heat pumps work together with air handlers to supply your home with warmth during the winter and cool air during the summer. Learn how this equipment operates and how to care for it for optimal comfort throughout the year.

What Is an Air Handler?

While many Birmingham, AL homeowners are familiar with heat pumps and their function, the air handler is a lesser-known component which plays a big role in indoor comfort. Air handlers are paired with heating and cooling equipment and manage airflow in the home. The air handler is the indoor component of a heat pump system and contains critical components housed in a metal cabinet.

Air Handler Components

The air handler cabinet houses components which work with the heat pump for indoor comfort control. Within the air handler cabinet, you’ll find:

  • Blower motor, which moves air through the duct system
  • Evaporator coil, which absorbs heat from the air within your home for cooling and expels refrigerant heat into the air for heating
  • Air filter, which removes airborne contaminants from the air circulating through your HVAC system

Some air handlers for heat pumps also contain electric heat strips. These heat strips serve as a backup heating source for heat pumps when temperatures drop for extended periods.

Heat Pumps and Air Handlers Work Together

Heat pumps and air handlers work together to deliver the conditioned air your home needs throughout the year. They maintain comfortable indoor temperatures whether it’s hot or cold outside.

Air handlers help heat pumps perform heating and cooling processes and circulate conditioned air into the home. The air handler’s evaporator coil aids in the transfer of heat between indoor and outdoor air. The blower motor moves air between indoor and outdoor spaces.

Care for Heat Pumps and Air Handlers

Both heat pumps and air handlers need routine maintenance to perform well. Because air handlers and heat pumps operate all year and provide both heating and cooling for Birmingham, AL homes, we recommend preventative maintenance by skilled HVAC technicians every six months.

Preventative maintenance provides necessary care to undo the damage of wear and tear between the heating and cooling seasons. Technicians inspect components so they operate more efficiently and lower energy bills.

They tighten and lubricate bearings and belts within the blower motor. In addition, they clean the evaporator coil to eliminate dirt and debris. If neglected, this buildup reduces system efficiency.

Air handler maintenance also includes an air filter change, if needed. We recommend an air filter check monthly. For most Alabama homeowners, a change is needed every two to three months. During the summer and winter, heat pumps and air handlers operate heavily – this frequent use can increase the need for filter changes.
