"My daughters a/c went out when it was 100+ and I referred her to Ian whom I had the pleasure of working with for many years. It was after hours but he was willing to come out. I can't remember what the issue was but he was able to get her a/c back on line. He is a man of integrity and truly cares for his customers I recommend A&S for all your heating and air needs."

"It was fine. There was an additional charge but I'm not surprised because I had a dryer vent that is very complicated. We negotiated and told me what they will going to take to do it. I was fine with it because I know my dryer vent. For me, to call somebody and do that specifically, it would have been more money. I feel good about it."

"Not only does Absolute Chimney work and refurbish Chimney's they also clean and repair HVAC air ducts, these guys are real pros at what they do. I would have not known my air ducts had holes in them if wasn't for Keith and crew. It was cooling and heating my attic and blowing fiber glass into house each time I used the heating and air unit. Thanks to their team I can breath and stay warm. Excellent Job Keith. Thank you."

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

Heating and Air Conditioning questions, answered by experts

The top reason to purchase an HVAC maintenance contract is the fact that it ensures you are detecting problems before they turn into expensive fixes. Secondly, this type of contract provides priority service, which is nice if it’s peak busy season. Finally, an HVAC maintenance contract provides discounts on parts and labor for repairs, which can save you a good amount of money if your unit breaks.

A frosty expansion valve that isn't blowing out cool air is a sure sign that it’s time to replace it. It might also be time to replace the TXV valve if your AC unit switches off soon after turning on or if you have poor airflow in your home.

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.

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

The DOE is phasing out AC units with SEER ratings that fall below 14 or 15. The exact minimum rating depends on your region. In the northern United States, new ACs must have a minimum SEER rating of 14, though you can still buy and install older systems as long as they were compliant when they were manufactured. In the southern and southwestern United States, you cannot buy or install older air conditioners with lower SEER ratings. The minimum rating is between 14.5 and 15, depending on the power of the unit.
