I called around twenty stores looking for a specific part. No one would sell it to me because I’m not a HVAC contractor. I called a1 the receptionist turn it over to the parts specialist and was able to get it for me. Drove all the way from Ontario and would do it again if I had to.

During today's 4/1/26 incident on I-84 one of their vans decided to use the emergency lane instead of patiently waiting like everyone else even seeing no one was being allowed off the interstate. We all had places we need or wanted to be this show a lack of professionalism and care for the community. Update: I see that the owner is working on the situation and am updating my rating.Posted on David FTrustindex verifies that the original source of the review is Google. just had a complete HVAC replacement system installed, AC and furnace.

Gerry was just at our house repairing a breaker by our AC unit. After completing the job he stayed to help us troubleshoot our thermostat. I had shoulder surgery so installing it would be very difficult. HUGE thanks to Gerry for delivering exceptional customer service and being a compassionate person. He wouldn’t even accept a tip so please recognize him A1 👊🏻Posted on Rick BeelerTrustindex verifies that the original source of the review is Google. Our technician quickly identified the problem and helped us fix it at a good price. I was preparing myself for a total replacement cost, and was pleasantly surprised to not get any sales approach at all. Thank you!Posted on Nancy UpchurchTrustindex verifies that the original source of the review is Google. I use A-1 Heating & Air Conditioning prepaid service program in both the spring and fall. I recently had the spring maintenance performed on my regular air conditioning unit and my ductless system in my upstairs. Now I am ready for the warmer weather. The technician "Dylan" was very knowledgeable and professional and explained everything he was doing. Thank you for your outstanding service.
