What Our Customers Say

"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.

"Happy with there service. Josh the electrician and Ed the plumber were both prompt, knowledgeable, and helpful in deciding what would best fit our needs."

JASON C.

"Josh Butler just left our home. That dude is excellent! Our home is an older home. He explained what he was doing and cleaned up issues with our wiring as he worked. The living room was left clean and tidy and he was friendly. I learned about the loyalty program and with work on our AC units I will probably join. I had a quote as well on the AC units getting installed in our home, Nathan Fisher was very professional and took measurements of my home and explained how much it costs and why. I am very pleased with both of these guys. I am pleased to say We are a Hep family and I will call again."

David P.

"On time, found the problem quickly & was able to repair with minimal work & supplies. Would recommend him to anyone. Very courteous & efficient."

Gail E.

"My HVAC system went down on a late Saturday night and i called HEP right away. They were calm and friendly on the phone, which allowed for us to get a tech out to my home. Justin came to my house at 7pm and did not leave until the problem was solved in every aspect of my issue at 11:30pm. I currently have a pregnant wife and he understood we needed to get air moving again. We worked late into the night to make sure we could have cool flowing air for the night. Once the job was completed for the day, he came back a second day to install new wiring within the home for the thermostat to the HVAC. He found and fixed previous issues from the prior homeowner and left my home better than how he found it. I am extremely appreciative of Justin and if you call HEP around the Knoxville area, I will request him in a heartbeat if I ever have any more issues and I think you should to. Thank you, Justin for your help and expertise."

Jeremy S.

Jacquelyn G.

"Josh Bulter has done a wonders job on my kitchen and electric to it. I can cook again probably that I haven't had to do in 2 years. Thank you so much for your hard work, and your great personality. I hope we get you again when we have another issue down the road."

KELCEY F.

"Josh Butler came fixed my power & was very efficient. A very nice electrician to work with."

Annie R.

"Josh Herndon with HEP came out to install a gas line to our generator! Very professional and went above and beyond to make sure the job was done right! I highly recommend HEP and Josh for anything you need done! Happy customer here!!"

Ben S.

"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!"

Essential lighting for safety after dark

Common Generator Types Serviced by HEP

Standby generators for whole-property coverage
Portable units for targeted or temporary power
Inverter generators for sensitive electronics
Commercial-grade diesel and natural gas models
