“Wonderful experience with One hour heating and Cooling and Chad Nathan and crew. They did a wonderful job. Wasnt happy w the trane thermostat so they had Nathan come out early the day after the installation and put a better thermostat in. I was dreading the whole experience but they made it look easy. All very polite and capable. ⭐️ ⭐️⭐️⭐️⭐️”

“I had an awesome experience with Rob. He was very professional, found the issue very quickly, and was in and out. The prices are very reasonable and they have a maintenance program that really fits the bill for what I need yearly. I will 100 percent be using them while im living in St. Louis. They also were able to get me an appointment very quickly. Start to finish I am very impressed.”

“Excellent overall experience, professional installation and affordable price. I had an urgent situation with two ducts that were preventing me from hanging drywall. I called about 12 HVAC companies, and One Hour was the only one able to accommodate me on short notice. I cannot recommend One Hour Heating and Air Conditioning highly enough!”
