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.

Oscar was such a professional and knowledgeable technician. He was on time and displayed exceptional communication. Everything was patiently explained and he was polite and friendly throughout the service. This company proved itself trustworthy and reliable from the start. Customer service is the number one reason for our loyalty to certain businesses, and One Hour Heating & Air Conditioning hit the mark. I highly recommend them!

Oscar was outstanding! He walked me through the process and what potential issues I may be having. Explained the whys and what options I had. I was able to make a decision without obnoxious pressure. Afterwards, he got me set up and now my heater is fixed just in time for the weekend freeze. Most importantly, my wife and daughters will be happy. Thanks! Much better than Goettl and super happy to be able to support a Woman Owned Small Business. Take care of this gentleman, he’s the right type of employee.
