“Austin Schmidt is professional and extremely knowledgeable. He is polite and friendly. Can’t say enough great things about One Hour AC & Heating. I kept forgetting to call to schedule my maintenance appt and they actually called me! Highly recommend this company. A friend of mine was here when Austin arrived and after he explained everything to me, she took his card so she can use them as well.”

“Matt, our HVAC technician, was great at communicating what he was doing and what was needed. He showed me photos of the before and after of all he did. One photo was of a pretty serious problem. His recommendation to repair and prevent future problems worked well. For a little more than the cost to repair, I got his recommendation of an excellent filtering system. I trusted in making this choice bc of Matt’s clear explanations. Very happy with this company’s work.”
