"I contacted Costa on a Saturday and he came over the same day to look at the work I needed to be done. He provided a quote the same day and scheduled the repairs less than a week out. Costa is very professional, thorough, and explained everything. He is always friendly and approachable. He completed the work in 1 day and I will definitely be hiring him again for some additional repairs in the future."

"Sam the Air doctor took time out of his very busy schedule to come and help me out with my thermostat. It took him seconds to figure out what the problem was with it. Not only he fixed the problem right away but also gave me advice on how to keep my ac unit working the way it should. His prices are very fair. Never felt like he was charging more than what he should for his work. From now and on we will call anyone else. All we need is our Air Doctor. Very happy client over here. Thank you again."

Heating and Air Conditioning questions, answered by experts

Yes, a frozen AC unit can affect your indoor air quality since the reduced airflow won't be as effective at removing air pollutants, like dust and other allergens. Additionally, ice around the unit can create excess moisture, leading to mold and mildew that can damage your home if you don’t catch it early.

AC evaporator coils should be cleaned at least once per year to keep your unit in good condition. For optimal performance, consider cleaning them twice a year—once before and once after the main cooling season. More frequent cleanings may be necessary for older systems, units with performance issues, or those in climates with high levels of humidity, dust, and dirt.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

No, it isn’t necessarily bad to turn your AC on and off frequently—contrary to popular belief. Even if you stop and start your AC throughout the day, it won’t use as much energy as it would if you ran it nonstop. 

If you’re concerned about your power consumption and energy costs, there are a few simple ways to use your AC more efficiently. Regularly cleaning the filters, scheduling routine maintenance, and using a programmable thermostat are all great choices.

While your AC unit may still run even if its capacitor is going bad, doing so takes a lot more energy, so it can drive up your electric bill and cause further damage to your AC unit’s parts. If you suspect a bad capacitor, it’s important to have a professional diagnose and fix the problem before you continue to run your AC.
