We got an appt right away with theough our warranty company which has never happened before. Joshua arrived on time, very knowledgeable, professional and polite. Had the heat pump back working right away. Highly recommended the company and Joshua.
Joshua was great diagnosing and fixing my furnace when it went out. Near zero temps outside and temps dropping inside quickly. He showed up quick, diagnosed, fixed and explained the problem and potential future issues with my old furnace. I will be using One Hour for my future furnace and air maintenance, and heavily recommend them.
I recently had One Hour Heating and Air Conditioning of O'Fallon install a new HVAC system at my home, and I couldn’t be happier with the experience. From the moment the team arrived, they were professional, courteous, and took the time to explain everything to me. The installation itself went smoothly, and I could tell they really cared about getting it right. They made sure I understood how the system worked and even offered some helpful tips for maintenance. Since the install, my home feels more comfortable than ever, and I can already see the difference in efficiency. I really appreciate their attention to detail and dedication to quality. If you're looking for a reliable HVAC company, I highly recommend One Hour Heating and Air Conditioning of O'Fallon!

I highly recommend this company. Thank you for getting us fit in so quickly
