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.

Austin arrived on time and was very thorough in his explanation of services to be performed. After his evaluation of the system, he took the time to review some key items for the thermostat and the system.

We were told by another company that we needed a new thermostat and were given a quote that seemed very high. We decided to call One Hour Heating and Air Conditioning for a second opinion, and they were able to come out the very next business day. Matt thoroughly reviewed our HVAC system and quickly determined that there was nothing wrong with the thermostat at all—just a disconnected wire. He reconnected it, and our system has been working perfectly ever since. We truly appreciate Matt’s honesty, professionalism, and expertise. Thank you to Matt and the entire One Hour Heating and Air Conditioning team. You will definitely be our first call next time!
