“I don't often write reviews, but my experience with this HVAC company was superb. They answered my call in the middle of the night and came out the next morning for an emergency repair. The level of service, communication, and attention to detail of the technician (Cobi) was top notch. He got our malfunctioning unit working, performed needed maintenance on both our units, and explained everything he was doing and why every step of the way--as well as how I can better protect my systems going forward. I appreciated it as a first-time homeowner.”

“Jacobi was amazing! He explained everything perfectly and was able to fix my AC on the spot. I would recommend him and this company to anyone looking to get a knowledgeable technician that will give you a more than fair price. I'd give him more than 5 stars if I could!”

“Jacobi did a great job. He found a shorted wire that I would have never found. Spent extra time to run diagnostics after the repair to make sure everything was working properly. And he was patient to explain everything to me.”

“Cobi came out after hours on the hottest day of the year, when our AC gave out mid-dinner party, and was an absolute lifesaver. Calm under pressure, deeply knowledgeable, and generous with his time. He explained each step clearly, walked me through preventative care, and even cleaned the drain line at no extra charge. Just as impressive, he was a genuine pleasure to talk with, easy, thoughtful, and grounding, the kind of presence that makes a stressful moment feel manageable. You don't often meet someone who elevates a service call into an experience you actually appreciate. Five stars, no hesitation.”

“Jacobi was great! He showed up on time, was very polite and professional. He explained in detail what his recommendations were to avoid issues in the future and what the consequences could be if we waited. No pressure whatsoever which made it easy for us to decide to take care of the issue before it becomes a problem. After the work was completed Cobi cleaned up the areas he was working in and buttoned up our hvac system. Thank you again Cobi for the great job you did. And a thank you to 1 Hour Heating & Air, thank you for training your technicians to look for potential issues that could be resolved before it turns into an expensive problem. We appreciate the great service.”

“Jacobi was great! He diagnosed our problem quickly, a drainage issue that cause the A/C to shut down. Not only did he get A/C back running in 5 minutes but by the end of it all taught me preventative measure to take to ensure the issue wouldn’t happen again. Was done in less than 30 minutes!”

“I had a great experience with Cobi! He repaired my air conditioning quickly and efficiently. He was professional, knowledgeable, and explained everything clearly. The whole process was smooth, and my AC is now working perfectly. Highly recommend him if you need fast and reliable service!”

“Cobi fro Cedar Park was our technician and he was fantastic. Very professional. He diagnosed the problem in less than 5 minutes and fixed it. Very fast, friendly, professional service. We will definitely call the Cedar Park branch again.”

“The team was polite, prompt, and very knowledgeable. DeVonte was our technician and in addition to being friendly and clear in his explanations, he went above and beyond to help us with our warranty, which saved us nearly ten thousand dollars. I highly recommend their services.”

“Cobi was my savior tonight! It was a saturday evening and I had airbnb guests at the house, and the AC stopped working! He was there right away and pinpointed the problem. He was truly great to work with. The whole process with this company was streamlined and I can't recommend them highly enough!”

“Jacoby expertly completed the tuneup service for the two AC systems at our home today (4/23/2026). He was thoroughly friendly, courteous, and professional. I think his work was far better than the service we received from another provider in previous years. I'd highly recommend Jacoby and this company. Thank you.”

“I would give TEN stars! Tina and Ismael were so friendly and professional and helped us get our AC fixed well and promptly! Of course, the timing of the repair we needed really put us in a pinch, so we appreciate their help even more!”

“Devonte was great, super polite and professional. Only place I could find that could come out in a Sunday, and we’re here about 3 hours after I called. Found the problem and got my AC running again.”

“Cobi was by far the most knowledgeable and professional HVAC tech (or any tech truly) we’ve ever worked with!! He immediately knew the problem and worked hard to fix it. He went above and beyond to make sure we knew what caused the issue and what he did to remedy it. He made sure we knew what he was doing during each step of the process. We will ONLY be requesting Cobi to come to future HVAC work at our home. I cannot recommend Cobi enough!!”

“Punctual even on a Saturday morning means good service. Parts on hand in van to help me get up and running. Fair price and good service. Shout out to Jacobi. Guess I’m updating because I needed them again and once ore, it was Jacobi. Same day service. Efficiency and thorough plus it didn’t cost me an arm and a leg. Really glad I was able to find them again when I went looking. Will call next time for sure.”

“Cobi was great. He was friendly and informative about the entire process and showed me exactly what was happening and why. He was thorough, polite, and professional!”

“Jacobi did an outstanding job. He is punctual, thorough, and spends whatever time it takes to provide excellence on every detail. He is an A+ employee!”

“DeVonte was our AC tech and did a wonderful job. Price was slightly high imo for a cleaning, but he was thorough and showed me what was wrong and how to fix in the future, which I appreciate. Customer service was prompt in getting someone out to my house, offered flexibility. Overall I feel pleased!”

“The inspection by the service technician was detailed and informative. The recommendations will be helpful for planning as Summer arrives, but I am glad to know my HVAC system is in good working order. Thank you Devonte.”

“We had an AC drain line blockage. Jacobi spent the time to figure out where the blockage was and how to clear it. I am completely satisfied with Jacobi’s work and explanation of what needed to be done to fix. He even spent extra time cleaning up the area around our attic unit. Thanks Jacobi!”
