Jordan, Brayden, and Kaleb just wrapped up the job at my place and I could not be more pleased. They were professional, kind, and went above and beyond. My wife and I are building a house in Bulls Gap, and needed to hook up a pressure pump. I didn't realize what all would be needed, but they nailed it. They installed a pressure tank under the house and finished all of the piping and fittings. Because we don't have electric for our pump house, they got my generator running and made sure everything worked as it should. I won't use anybody else going forward. Thank you, guys! Y'all are awesome!

Jonas F.

Shawn, Adam, Josh, Robert and Stephen are exceptional All went above and beyond to get my electric on after 7 days without power. Superb team!

Jan J.

Josh B was amazing. Effectively found my problem and got my power back on. My grandson will be happy that he will not be in the dark and have another mental episode. Thank you so much to the HEP team getting me in the service rotation with a hectic storm schedule.

Emily K.

HEP came promptly when we had loss of power due to storm damage. In fact, this is the 3rd time this has happened due to falling trees. HEP has been our go to electrical contractor each time because of their dependability, fairness, and quality of work. Zack did a great job. Very courteous. Hope to use him again soon for some other work.

Wayne M.

Our eleven-year-old heating and air conditioning system failed early in the Summer. We called HEP and after some discussion with their advisors we decided to invest in a state-of-the-art HVAC system manufactured by Trane and sold through HEP. It was installed quickly and efficiently and without delay by HEP service men. Part of the attraction was the Warranty offered by HEP which included a three-year-maintenance-and inspection-agreement on all household plumbing and electrical equipment, as well as a full ten-year-parts-and-labor Warranty on the HVAC system itself. Subsequently, we required service on our hot-tub and HEP's response ( from serviceman Richie) was quick, professional, and reasonable. We found him to be courteous and helpful. The problem turned out to be minor and we were only charged accordingly and fairly. We intend to continue to be HEP customers for all of our plumbing, electrical, and HVAC needs for the foreseeable future.
