What Our Customers Say

"Todd Farner is very personable and arrived much faster than I expected. The repair window was for between 4p and 6p and he got here at 3:50p! My house was a wreck and Todd did not judge and I am so grateful for that. Todd was very informative and explained to me what the issue was and luckily it wasn’t too major. Todd also told me about this great maintenance plan that they offer and they will inspect and maintain some water, HVAC, and electrical issues: just ask!"

Aria W.

"Todd Farnar, showed up as promised, issue diagnosed, priced, and repaired quickly. If I ever have the need for HEP again, I will ask for Todd."

James D.

"First of all let me say that every interaction I have had with HEP technicians has been exemplary. This ranges from replacing a hot water heater to general plumbing to general electrical work. Today’s kudos go to Rick (electrician) and Randy (HVAC). Not only did they know what they were talking about (not a given in today’s world) but I felt like they were family before they left. On top of that Allen came back out at 6:30 to write up a quote. One stop shop with high quality. It can’t get better than that."

Laurie M.

"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!"

Jonas F.

Ron B.

"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.

"Jessie the Electrician and David the plumber were amazing. David went out of his way to try and help me fix my problem. When there was no solution other than a new countertop he made sure I was taken care of. Chris came out and quickly helped me so that I can begin using my kitchen again."

Christyn K.

"Todd and Kenny stopped by today to do an HVAC checkup as part of my annual master agreement They were prompt, courteous and professional. I appreciate their advice and take it seriously. I will definitely continue to trust HEP with my homes HVAC, plumbing and electrical services"

Andrew W.

"Ric was absolutely superb as an experienced electrician and simply as a professional. It is so rare to see exceptional customer service these days and Ric (as well as those who took calls) were extremely professional. Ric went out of his way...after hours at that..to complete a job. After I mentioned I wanted the maintenance plan (recommended by 2 of my neighbors), he went out and documented make and model of our HVAC Units for the future reference of those who may call. Exceptional. A friendly gentleman; I am relieved that I know our family has someone and a company we can depend on for so many things.."
