“James Buzz is amazing! Upfront and gets the job done. Got there in a timely manner and worked in a timely manner to restore my AC. He even went above and had moved my neighbors trash can so the trash man could reach it due to his vehicle blocking it. Definition of going above and beyond the job.”

“Cemy was my ac technician today, he showed up when he was scheduled. Probably the best tech I’ve ever had for any type of job. He quickly figured out the problem and fixed it. In addition, he was engaging in our conversations , and obviously knew what he was doing. My only advice is to find more people like him, truly outstanding!”

“I had the absolute pleasure of working with Sean today, who exemplifies the upmost professionalism, expertise, and outstanding customer service. From the moment he arrived, Sean was courteous, punctual, and fully prepared. He really took the time to explain every aspect of my questions very clearly, with perfectly executed responses. What truly sets Sean apart is his commitment to excellence. He worked meticulously, respected my home, and ensured everything was running absolutely perfectly before he left. He made sure every check and balance was done properly to a T. His demeanor was calm, very friendly, and confident , and professional – qualities that made me feel completely at ease throughout the entire process. Sean is a shining example of how every technician should perform. He not only fixed a problem we were experiencing, but also set a new standard for what great service looks like with One Hour Air. I can’t recommend him highly enough! Thank you, Sean”

“I cannot say enough good things about Calvin Jones. Calvin is special. He is first and foremost a superb and capable heater and air expert. He is courteous, smart, and efficient in his craft. He is quick to find a problem, and he is extremely professional as he goes about the business of repairing the problems he finds. He explains things extremely well, he does top quality work, and he cleans up after his repairs. We enjoy his company, and we are not going to be very receptive if and when the Duggan's front office tries to send anyone other than Calvin to our home in the future. I consider Calvin the "best of the best" and he should be treated as such by his leadership. Thank you, Cal.”

“I can’t fully express how outstanding my experience was with Cullins One Hour Heating & Air Conditioning. From start to finish, everything exceeded my expectations. I initially worked with Jake, who quickly diagnosed the issue with my old unit and clearly explained my options. While I hadn’t planned to replace the entire system, Jake was incredibly helpful when I asked about it—offering excellent solutions and, to my surprise, scheduling the installation within just 48 hours. The installers, Xavier and Jose, were prompt, professional, and respectful of my home. They completed the job efficiently and ensured everything was left exactly as they found it. I highly recommend Cullins to anyone in need of heating and air services.”

“Terrell was very knowledgeable and did a great checkup on my AC system! Showed me everything and provided me with a few good tips. Hopefully my original 10 year old system will make it another year? If not I know who to call 1HR baby💪”
