Trevor was exceptional
Our furnace stopped working. Trevor McMillen, the technician who visited our house on the same day we called for help, was exceptional. He was honest, efficient, and quickly diagnosed the issue. He fixed it, provided great advice on maintenance tips, and made sure everything was in order. Thanks ATC team!

Excellent service!
Excellent service! A small part in the furnace needed replacing. The serviceman fixed it and cleaned the insides a bit, and we were back in business! The cost was very reasonable, too. Thank you!

Fantastic service and quick fix
We had an issue with our furnace due to an electrical problem. The original contractor had used improper materials during installation, which caused the issue. After finding Air Treatment through a Google search and seeing their excellent reviews, we decided to give them a try—and they didn’t disappoint. We called them on a Sunday morning, and they promptly dispatched a specialist. Within two hours, Trevor McMillen arrived and got to work. He was incredibly knowledgeable, diagnosing the problem quickly and fixing it within a few hours. He was very professional, knowledgeable, and friendly. As new homeowners, we appreciated the quick HVAC 101 he gave us :) It was a helpful bonus! Thank you for the fantastic service and for getting everything back in order. It was money well spent!
