What Our Customers Love About Us.
“ASCEND was awesome for our home in Colleyville. When our unit failed, they were the first to respond, diagnosed the issues quickly, got us a temporary fix, and gave us the best price for a new unit out of 3 bids. Very professional and replaced it fast. We strongly recommend ASCEND!”
Jim Barker

“Jay and his team are phenomenal, best service in DFW! Their pricing is great and their techs are top of the industry. This is the ONLY company I use for my house and all my commercial properties throughout the metroplex.”
Jon Davis
DFW Metroplex
“Jay and Tina have been fantastic to work with. They are extremely organized, responsive, and are always quick to jump in whenever I have a commercial HVAC issue at one of our properties. I can’t recommend them enough and look forward to working with them again.”
Sterling Lubchenco

“I came home and found our AC not working after 5pm. Ascend not only came out within an hour from the other side of DFW, but took the time to diagnose the issue, fixed it without having to order parts, and didn't rack up a giant bill. These guys are the best around!”
Lucas Dooley

“Ron and Jay are one of the most honest people working in this field. Another company told me I needed a whole new system; all I needed was a blower motor and a capacitor. Thanks to Jay my units keep chugging. Honest techs who don't just take your money.”
Anthony Perez
DFW Metroplex
“I have worked with Jay Sanford for years and he has come through for me on many construction projects. Him and his team can do it all and they are the only ones I trust on my house HVAC system—just installed a complete unit at a good price. Highly recommend!”

“Jay and his team gave me the best deal out of 4 other companies for a complete install. Not only that, but the equipment was great—nothing cheap. Ron was very knowledgeable and professional through the whole process. Definitely recommend to anyone!”
