AC Installation & Replacement

There are many telltale signs that an HVAC unit might need to be replaced. If an HVAC unit is over 10-years old, smells terrible, blows warm air, or produces subpar results as energy bills keep rising, give us a call!

“Cody, Joe and Payton were all great. Very friendly and professional. My outlets needed to be added on the wall not in it and it all looks great. I’m very happy with the work that was done. I’ve been needing electrical outlets in this room for years!!! I would recommend them. I may have other jobs for them as well.”

“After having several bad experiences with other providers, Kenny was honest, fair and quick to diagnose and solve my AC issue. Super appreciative of the fast response and honest guidance. He was willing to walk me through everything that he was doing.”

“Had replacement thermostat installed. On Thursday July 3rd, 2025 Javier was very knowledgeable, professional, forthright and personable. He did a great job and also checked my AC while he was here. Would certainly recommend him as a tech for others. Thermostat price and installation seemed a bit on the high side as I could have purchased the same thermostat at one of the big box stores for a lot less. But I've used 1-Hour Heating several times in the past, and I've always been pleased with their work and the techs' professionalism.”

“Bobby Pence was very knowledgeable about the AC unit. He gave great tips on the upkeep of the unit and things that would help with the longevity of it. He was very transparent and upfront with every question I had and didn't try to sell me things but he did recommend what should be done. There was no sales pressure at all or " oh you need a new unit right away " he took the time and effort into teaching me about everything he was doing. If I have to call One Hour again I'm going to try to request him personally and if it's not an emergency I'll wait for him to be available to come out.”
