Janie W.

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.

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.

After having a new hvac system installed yesterday, a quality check was done today by Justin Weld. Not only did he make sure everything was done correctly, but he also fixed the breaker to the furnace that kept tripping (we only noticed it after the installers had already left). Justin was very professional, extremely helpful, and thorough when it came to making sure everything was working properly before he left. Huge thank you to him!!

Timmy C.

Joshua Butler was our service technician today. He was very fast and efficient. He identified the problem immediately. Had the part on his truck. Fixed the problem. Checked to make sure everything was working correctly before he left. Thank you, Josh!

Cynthia M.

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.
