My home has never been this comfortable
Air Treatment replaced my old heat pump and water heater. From the initial design and estimate to delivery, they did a great job! I appreciate that they took their time to design a solution specifically for my house, including some modifications to duct work that really helped overall performance. My home has never been this comfortable. I was also impressed with their price. If you're an informed consumer looking for better than entry level, you'll be very impressed with what they can provide at their price point. I would absolutely recommend them to anyone else looking for a new HVAC system.

Had to call late on a Monday afternoon as heat pump kept blowing fuses. Mike came out the next day to diagnose a faulty connection in the disconnect box for the air handler.

I am very appreciative of this excellent service! Will continue my yearly service contract with Air Treatment Heating & Cooling.

Very Happy With This Technician
Tech was late, but appropriately apologetic and professional to discuss things with. I thought that he was supposed to have 2 other guys with him to help, but it was only him. He worked really hard. He was courteous and careful. He cleaned up all messes. He did run into an odd issue, but told us to contact the office to schedule someone else to fix that issue. It would have been nice to have a team here for consensus. Very happy with this technician. He deserves a raise for how hard he worked.

Phenomenal service from Air Treatment and Cooling! Their technician, Mike McEwan, did a fantastic job fixing my broken HVAC damper.

Amazing Service on Our Commercial AC
Huge shoutout to Air Treatment Heating & Cooling and especially Dylan for the amazing service on our commercial AC unit at our print shop during this brutal heat wave. I was preparing myself for a repair bill in the thousands and possible downtime, but Dylan quickly diagnosed the issue, was completely honest about the filter situation, and got everything running without trying to upsell unnecessary repairs.
Best part? Our shop never went down and we were able to keep production moving the entire time, even in this crazy heat. In the printing business, downtime can cost a fortune, so we really appreciated the fast response, honesty, and professionalism. Good people are hard to find these days — highly recommend Air Treatment Heating & Cooling for commercial HVAC work!
