"The service that we received from Aires Heating and Cooling, LLC was great. I really can't say how it could have gone any better. Our furnace broke down, tried a couple easy troubleshooting steps over the phone, and when we couldn't get it going, the tech was over as soon as he could. This is the time of year where he was busy with other customers, so the amount of time we waited was explainable. Didn't have parts right away on his van, but we didn't wait for more than 24 hours before he found another tech that did have the parts for our furnace. Excellent friendly service. Thank you very much for all the help, Aires Heating and Cooling, LLC."

"Austin installed A/C in our newly remodeled home and we will continue to go through him for any future HVAC needs. He was efficient, thorough, and transparent throughout the entire process, answering any questions we had. As well as reassuring us we could reach out to him after the job was done if we ever had any problems down the road. We highly recommend his services and the peace of mind he provides!"

Heating and Air Conditioning questions, answered by experts

Evaporator coils in HVAC systems typically last around 10 to 15 years. However, their life span can be longer or shorter based on factors like the frequency of your HVAC system usage, whether regular maintenance is performed, and environmental conditions. Regular maintenance, such as HVAC system cleaning and coil inspection, can extend the durability and efficiency of your evaporator coil.

Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.

To diagnose a bad HVAC or AC damper, assess the airflow from your vents. For a manual damper, close it, run your system, and check for airflow. If air is still coming through the vents, the damper is likely faulty and needs repair or replacement. For an automatic damper, turn on your HVAC system and monitor the airflow and room temperature. Signs of a problem include low airflow, a room that won't maintain its set temperature, or a drafty feeling. If you suspect a faulty automatic damper, you may need to hire a professional for repairs.

No, you don’t need a ductless unit in every room. Ductless AC units don't work the way that window units do, where the air doesn't travel outside that room. The indoor air handlers all attach to the outdoor condenser. While the air doesn't travel the way that traditional ductwork would, the ductless AC units create zones so that one part of the home can be cooler than another. They can spread effectively enough that indoor units only need to be placed in main living areas.

While it is possible to add Freon to your AC unit yourself, it is not recommended. In fact, the U.S. Environmental Protection Agency (EPA) prohibits the handling of Freon without a license. Freon is a dangerous gas that can cause irreversible damage to your AC or yourself if not installed correctly. It is worthwhile to hire a professional to add Freon to your AC.
