"Aire Serv did a great job for me. Tuned up my main AC unit. I expected more charges but everything checked out fine. Thanks! The technician ran short of time, due to the rain. He could only get to one of the units and said they would follow up the next day to reschedule. Unfortunately, they did not follow up and I've not had the second unit completed."

"We purchased a new Clayton home in late 2023 and everything seemed good at first. After several times over a year of having HVAC techs from Clayton come out for a cooling issue, eventually the warranty ran out on the AC. Then we had another supposedly reputable HVAC company come out and said it was a lot of issues outside and would cost almost $2000 for a repair that may or may not work. We went thru Angis list and got in touch with Quality Air. The tech came out and went thru our system and located the issue inside that was never installed from the Clayton homes store. Nathan had our system up and running and has been cooling excellent ever since. Before, our system had a very hard time keeping up with the selected temp.. but now we sit in cool comfort and it has never ran so great. Thank you Nathan, and thank you Quality Air!!"

"George was professional and friendly. He cleaned the air ducts throughout the house and included the vent covers. The machine was really loud, but efficient. He showed us how much dust and debris were removed. No wonder we were having allergies in the house. Within a few hours we noticed a difference in the air quality. Will definitely use Vent Service Pro in the future."

Air Conditioning questions, answered by experts

You can protect your air conditioner in the winter by turning off the power at the thermostat and performing routine HVAC maintenance in the spring. Regular maintenance, cleaning, and repair of your AC unit helps protect it and extend its life span. If you have a window AC unit, remove it from the window and store it in a dry place during the winter. Window units cannot withstand freezing temperatures. Keeping them in your window also allows cold air to seep into your home.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.

Yes, you can clean your air conditioner filter as a temporary fix for cleaning up dirt, but you’ll eventually need to replace it once the dust starts to accumulate. Use a vacuum with a hose attachment to clean your air filter at least once per year or more often if you have pets.

Trick question: There is no difference between an AC and a furnace blower motor. Whether you have central air and heat or just one of these, the same blower motor carries hot and cold air throughout the ductwork in your home. Certain systems may have separate blower motors for the AC and furnace, but each serves the same function.
