“Service tech Beau was here today to do a deep cleaning on my split unit. He was on time, very professional, and spent quality time taking care of the cleaning. He also gave me helpful recommendations. The office staff is also very nice to deal with.
I was shocked, pleasantly, at the cost. It was more than $1200.00 less than I was quoted by another company! I will be a life-long customer for sure!!”

“After a terrible experience with another company that misdiagnosed my one-year-old Minisplit compressor as having 'toasted' electronic boards (with a $2,000 parts + labor quote and a refusal to install my warranty-covered replacements), I was incredibly frustrated. They even suggested I replace the entire system for $12,000!
Finding a company willing to work on a Minisplit and install my own parts proved challenging. After 5 or 6 rejections, "One Hour Heating & Air Conditioning of Ellis County" was a breath of fresh air. They immediately agreed to help and sent a team the next day.
The technicians quickly identified and fixed a problem with the electric line feeding the unit. Once power was restored, my supposedly broken compressor worked perfectly!
I also had a great experience with Kortling and Brian.
Highly recommend.”

“DeVaughn was very professional, informative and thorough while inspecting my unit. He suggested that I get a part to prevent any further rust so I went ahead and purchased that. He cleaned my unit inside and out; free of debris and pollen. I been dealing with them for a few years now and they exceed my expectations every time. After about 5 years my unit is still holding up pretty well.”

“I called them at 6:30PM due to our system not cooling down the house. Our system was not responding to the thermostat calling for the cooling system to come on. They had a service technician at our house within 45 minutes. The technician had the issue fixed and told us to call if we had any further issues. Great company and feel confident that we have always been treated fairly!”

“Kelly was great, he worked with me on the best way to finish my basement, he was patient and let me bounce several ideas off of him and gave honest feedback and opinions. The installers, Sterling and Courtney, were awesome as well. They were punctual, tidy, performed quality work, and were not bothered by me asking questions and giving feedback on placement of vents. The phone staff was also very kind and professional. The price was very reasonable. Highly recommended!”
