Do you service emergencies after-hours?

Yes, we offer emergency services 24-hours a day, year-round.

How much will my service cost?

The size and complexity of your HVAC issue will determine the cost. Because our trained, licensed HVAC technicians must diagnose the issue before we are able to quote you an accurate cost, we require an appointment to be set to complete a diagnostic on your system. Once the diagnostic is complete, your One Hour® technician will walk you through all costs using our Straightforward Pricing® Guide so there are never any surprise fees.

“Our AC just stopped working late in the afternoon on a Friday and I thought we were going to be stuck without AC for a day at the absolute minimum with temps in the upper 90's. I called four places with late Saturday was the best I could expect. I called One Hour and was told they could have someone over in about 90 minutes. Coby actually arrived in a little less than an hour. He was polite, professional, friendly and did an amazing job explaining everything that was wrong and pointing out some other things that we would probably have to deal with in the near future. There was no high pressure, he wasn't trying to sell me on things I didn't need and showed me what everything was, the specs on the items showing failure or fatigue, etc. I approved the proposed job and Coby was just as thorough in his repairs as he was in his explanations. He got our AC back up and running, did a complete diagnostic and was finished in under two hours. I can't recommend One Hour or Coby highly enough, they're truly outstanding.”
