What Our Customers Say

"We used them last year for a new Trane and they were great. They did an excellent job protecting our home and the AC works great. Today we called for a service call on an older Trane and they sent a 20 year employee. He got us back up and running for a very reasonable service call. These guys are trustworthy and the kind of people you want working on your home."

"Alief Ultra did a fantastic job in a compressed time frame replacing our old damaged HVAC ducts and mixing box with a brand new up to code duct system. Professional and friendly, they were able to explain each step as they progressed through the removal and installation process. They cleaned the return air box and resealed it as a final touch to protect the intake system. Terrific job. I will be contacting them again when we begin investigating installation of a new system."

"Jeremy has given me the best customer service for over 10 years. He is always pleasant, honest, kind, and is very knowledgeable. Jeremy patiently answers my questions and looks out for my best interests."

"Every house we have ever owned in the Houston area, we have had Alief/Ultra maintain and service our heating and air conditioning. We have been a loyal customer for over 15 years and John has been so easy to work with. He is very knowledgeable and has saved us a few times when we had urgent issues. Also, I would highly recommend the service plan program as it has been a great value to us and has assured that our heating and AC systems are always tuned and ready."

"These folks gave us great service at a very reasonable price. Our AC had stopped working and two other companies looked at it and wanted to sell us on a total replacement for 5,000 to 6,000 dollars without finding (or at least telling us) what the problem was. It took Mike about 20 minutes to find a leak in our outside coil and we had it replaced for $1,650. We are retirees on Social Security and couldn't afford a total system replacement. The whole experience with the owner, Mike, the office manager, Anne, and the technicians, Ron and Sam, was positive and I recommend Alief Heating & Air Conditioning without reservation."
