“Awesome. The guys were on time, polite, respectful, did a great job cleaning up, answered all my questions and now just waiting on another crew to finish the modification. My new A/C units are Great. So happy! The inside unit was so very old it was well over due of getting a new one. Glad we decided to upgrade.”

“Randy to the rescue! He had water leaking from equipment installed by a different HVAC company and Randy came out first thing this morning and fixed it! Moving forward we will ONLY call Conover for HVAC servic. First class service!”

“My AC kept shutting off and I had been putting it off and just suffering in the heat for a while until I finally called a couple of companies. Not only was One Hour more affordable than the other company I got a quote from, but they were some of the sweetest people! I ended up purchasing and having them install a new unit and I’m extremely happy with how quick they were able to get me on their books and help me out. My house is now a cool 70 and life is already much better and less sweaty! Definitely recommend- great people offering great prices and products.”

“Our existing system was 28 years old and at the end of its life. Conner came out and evaluated our system and recommended replacement. We agreed and he gave us several options that included repairing our old system. We agreed it should be replaced and they installed it the next day. Good people doing good work and we highly recommend them to anyone needing service or replacement. Our installers, Dustin and Angel were fantastic and very knowledgeable. We’ll definitely use them again.”

“We’ve had this HVAC system in a new house for three years and we were having problems cooling our master bedroom ( actually it stopped cooling). We called 1 hour and they were out Johnny-on-spot and on-time( actually a little early). Conner handled the repair with aplomb. He is very knowledgeable, trustworthy, professional, and obviously enjoys what he does. It was a pleasure working with him for his advice and maintenance tips. They have earned my future business. Exceptional service. Very highly recommended without hesitation!”

“The family and crew are friendly, explained everything in detail, and set expectations. Their first visit was after 5 and couldn't get the parts that night. So they made a special trip to bring us a portable AC unit for one room and set it up. The next morning they arrived first thing and got our AC back on. They communicated often and kept their promises. I highly recommend!”

“Awesome, fast service! Chris was professional through and knowledgeable! We were up and running in no time! One hour guaranteed for sure , definitely appreciate Hannah as well very courteous over the phone , provided instructions prior to the tech arriving! Will forever use them for any future needs!”

“Update: We were having problems with too much condensation building up and One Hour came back and kept working on the issue until it was resolved. Very good customer service! We had to replace our HVAC unit. One Hour Air-Conditioning and Heating did a great job with our purchase and installation. They were quick, efficient and knowledgeable. Dakota and Christian are great workers and very respectful of property. They both have a good work ethic and attitude. It was wonderful to have them working on our hvac installation. I highly recommend One Hour Air-Conditioning and Heating!”

“We called One Hour Air originally because they were listed as the warranty contact for our air conditioner unit. I was able to speak to a real person within seconds of calling, even in July! They had an appointment window booked within a few hours, found our warranty information, and provided text updates throughout the process. The technician was friendly, fast and got the job done. We also signed up for 6-month tuneups because 1. They’re reasonably priced 2. The tech was not pushy at all in his pitch 3. We so appreciated the level of service. Thank you, One Hour Air.”

“I am extremely frustrated with this company. They completely replaced our air conditioning units (2) in the summer of 2023. Over the last year and a half we have had to call them out multiple times because our upstairs unit continues to stop working. They have not fixed anything, they continue to tell us it’s the air filters needing replaced. I called about 2 weeks ago because the air would not turn on upstairs again, they made an appointment and never showed and never called. I’ve since called them for the last week everyday, with no answer or phone call back. I am a very unhappy customer.”
