“Thanks again for getting us in at the last minute on a Friday at 3:30 in the afternoon. I also appreciate the cost saving on the repair to the unit. You guys installed the unit and have maintain it since 2018. Having the same folks means no mistakes or passing the buck on problems. Good job to the team.”

“I have had a lot of issues with my house that have been addressed poorly by companies and technicians. One Hour Heating & Air went above and beyond to make sure the issues of my system were not only serviced, but fully inspected to an amazing degree. Providing insight into how my system functions and where some future problems may be starting to arise. Even providing suggestions of what to do and a very reasonable quote if I would like them to do it. I have not had this kind of competency and quick response to issues like I have now experienced with One Hour Heating & Air. They will absolutely be my go-to from here on out.”

“The service was our mid year heat pump(s) service. Our technician was on time, courteous, and professional. He explained the need for a small part to be replaced on our oldest unit and quickly took care of it. Fortunately we signed up for annual service which provides us a discount on parts should we encounter the need. He was thorough and answered all our questions. While we have had service before, we were particularly impressed with his manners and professionalism! Great experience!”

“Our air conditioner stopped working during the summer. It took a few days for someone to come and look at it; however, our technician (Spencer) was so helpful and positive while working on our unit. He was able to fix everything within 2-3 hours and answered any questions we had.”

“I want to give Carlos the biggest compliment I can. Carlos was extremely professional and very informative about an issue i was having with my insulation. I appreciate him for taking the time to explain things to me. He also has a very pleasant demeanor and he did not take long completing the job. 5 🌟 STARS FOR CARLOS.”

“Cameron was amazing and was super patient and helpful in figuring out the unknown hvac noise. Turns out it was just the pump, phew for me. I’m super appreciative of his help and major bonus points that he already knows this new to me house. Would definitely recommend this company.”
