“Abdul did a very good job. He found a bad cap and replaced it. Very knowledgeable guy. The best I've had here in a few years. I will ask for him again. Thank you Abdul.”

“If I could give more than 5 stars, I would! John from One Hour Heating and Air was absolutely fantastic. From the moment he arrived, he was focused, friendly, and customer-first. He didn’t just breeze through the appointment—he took the time to walk me through everything he was doing, answered all (and I mean ALL) of my questions, and made me feel like a key part of the process. It’s rare these days to find someone who takes the time to educate you without rushing, but John did just that. No pressure, no surprises—just honest, clear feedback and a ton of valuable info. He didn’t act like the job was just another checkmark on the list; he genuinely cared that things were done right. In South Texas, our AC isn’t a luxury—it’s survival! And I’m so grateful to know I’ve got someone dependable and professional on my side. John, thank you for your integrity, your patience, and for being the kind of pro who doesn’t just “fix it and run.” You’re a gem.”

“I have worked with 3 different AC companies over the past 2 years. Today, I feel like I may have found my AC team. Champion was my tech and he did a fantastic job.. He was thorough, friendly and broke the information down for a novice like my self to understand. I will be using them for my AC needs going forward.”

“5 Stars!!! Jessie from One Hour Air is absolutely outstanding! He showed up after hours and still had the energy and enthusiasm as if I was his very first customer of the day. He was incredibly kind, professional, and helpful throughout the entire visit. It's rare to see someone so passionate and dedicated to their work—Jessie truly went above and beyond. Highly recommend him and One Hour Air for exceptional service!”

“Matt was great! He came in a hurry and got right to it. Somehow this WIZARD came in and saved the day! Even if it is for a short time on old, dying system. Prior to Matt coming to the rescue I had a different company come and try to fix the system and left after no joy. They left telling me the system was too old to put any money into and told me not to look into it. I think they may have sabotaged the system by “deleting” a wire… in order to get a sale of a new system so be careful. I would %100 recommend One Hour Heating an Air and next time I need something worked on I won’t look anywhere else after this experience. To your whole team, the Hobbs family thanks you!”

“I recently had Regan install a central air conditioner at my house. The Regan rep (Roland) did a awesome job specking out a replacement unit (mine was 25 years old). The install technician (Zack) did a really great job with the installation. I was very happy with my experience with Regan.”

“Ryan was very professional. He explained everything that he did to the unit. He made sure that we understood the problem with the unit. He also said if we had any questions feel free to call him. He's having another technician to come by to inspect the unit tomorrow with a machine he didn't have. We appreciate his honesty and professionalism.”
