What our customers say

Our AC needed attention, Ron Trent came over, checked it and refilled it. He returned the next day and reported that there was.a leak that was not fixable. We need a new unit. Yesterday (7/25), Brett Cox and Aavi showed up promptly at 9AM. They got to work immediately and worked nonstop for at least three hours. All three of these men very courteously an answered all my dopey questions. Mannerly! Also, they left my house cleaner than the way they found it.

Jacob and Ryan came out and installed a brand new HVAC unit at our house, only a few days after it went out. Their installation was quick, well done, and very professional! This is the second HVAC unit install they have done for me. Thank you to HEP once again!

Kyle M.

Chase just left from giving me a quote and I’ve got to say he was far better than I anticipated. He gave me more than one option on how to deal with my HVAC needs and explained things to where I could easily understand. He also gave me a solid foundation for using financing options. Thanks Chase!

The installation team Matt and Jacob B was very professional and really helpful in sharing information on the installation. This made our experience much more pleasurable considering the situation. I would recommend this Company and certainly recommend that Matt and Jacob B install AC in any situation. Highly recommended them for reliability, performance, professionalism, and customer satisfaction.

Dillon M.

Ronnie and Justin was absolutely awesome and professional they went above and beyond on installing our new HVAC system. Even though we had some issues with rhe salesman who sold us on a couple things and didn't place it in their work order they still both of the guess understood and listened to our frustration and made sure before they left that everything was to our satisfaction. If you need an hvac installed Iand u use help o would highly recommend to ask for Ronnie and Justin to come out they had the utmost respect and did extra things to help solve issues that was hot their fault at all. They definitely deserve 5 stars great men and so thankful for the quality and the time u guys spent getting us heating and air back.
