Awesone!!
Both professional and friendly! A good combination. The work was under warranty so I didn't have to pay anything. A great blessing! I would tecommend these two for any cooling, or heating, needs. They were great!!!
Jordan was awesome!! We just recently bought our first home and 2 months later the AC stopped working during a heat advisory. Jordan arrived an hour before scheduled time and has us cooling off 20 minutes later. He made sure everything was fully operational before he left!! He’s an asset to One Hour Heating and Air!!

Brody, was fast, efficient, and professional from start to finish! He explained the entire process thoroughly, made sure we were comfortable with the pricing, and confidently assured us he could resolve our issues—and he did. He arrived on time, communicated effectively, and completed the job quickly with no hassle. An added bonus was that my son has been interested in pursuing this same career field. He took the time to provide valuable insight, guidance, and encouragement, which meant a great deal to us. That level of professionalism and willingness to mentor someone speaks volumes about his character. I'm so glad I chose your company to meet our needs. Outstanding service and a job exceptionally well done. JOB WELL DONE, SIR! ⭐⭐⭐⭐⭐
I would totally recommend this company. To family friends neighbors enemies whoever! They came same day and repaired my HVAC. The owner and Technician (David and Richardo) were very professional and courteous. They were on time and quick.
My AC went out yesterday, I called at 7am and was able to get on the schedule. That was so fast. I have a service contract with them. When Ferrell got here he quickly diagnosed that it was the capacitor and he had what he needed in the truck. While here he checked my system and said everything seemed in working order. My house is cooling down .Thank you Dunn you've got great people.
