“Excellent service! Requested an appointment for my old Carrier AC unit which had stopped working. Quickly received a one hour window for the next morning. My tech was prompt, nice, and knowledgeable. He was able to assess the issue and provide a quote quickly and painlessly. They replaced the needed part right away. I also had them replace some other old parts and clean my unit. Ask about the OH club, they make it super easy and affordable to sign up and get your yearly AC and heater checkups. Overall, very satisfied with my whole experience, highly recommend!”

They arrived right on time, were very thorough with the inspection, and took the time to explain everything clearly. It’s great to see a company that not only delivers great service but also shows real appreciation for those who have served. Highly recommend One Hour Heating & Air—thank you for the great service and for supporting veterans and first responders!”
