Joe with Design Aire did a wonderful job replacing our old furnace with a newer version of the same model. He modified and updated ductwork with a filter housing and appropriate venting and gas supply line. The cost was reasonable.

We had an issue with a initial hook up of a central humidifier. the tech came out and found that a wire had been installed incorrectly and repaired it. They came out very quickly and completed the task quickly as well. Then before they left, they helped me set up the Trane app on my phone. Super job and super customer service.

Matt May was an excellent technician! This was our first experience with an all-electric HVAC system and heat pump, and he took the time to explain everything so clearly. He got our heat working and had the house warmed up before he even left. Super nice and very knowledgeable—highly recommend!
