What Our Customers Say

"UPDATE: I bought a new house and Robbie came out to fo a gas line test for me. Great service, as always. Socially distant, polite, friendly, and knowledgeable. Joshua from HEP came out to do the summer inspection and found an issue the company (listed in the review below) caused by shoddy workmanship. So glad I have now switched everything over to HEP. Will came out at 1:30am to fix my HVAC. I had a bad capacitor and the repair took 15 minutes. This was after Mike, at A1 Finchum told me he'd workedworked 16 hours and it would not be fixed until morning, and oh there were 3 ahead of me. Kicker, I have Multiple Sclerosis and can not tolerate heat. HEP was prompt and a lifesaver. Total cost was under $500. Much appreciated!"

Melissa L.

"HEP installed our Trane unit a couple of years ago and were here yesterday to inspect the system as part of our agreement with them. The technician was very nice, called ahead, arrived on time, put disposable covers over his shoes before entering our home. He did a thorough job with the inspection and gave us hints on the filters we need to be using for most efficient operation. We have used them for electrical problems and for plumbing issues and have always been very satisfied with the work. I like that they answer the phone when you call as opposed to getting a recording. When they give you a range on the time that they will be coming, they always honor it. We first used them for an electrical emergency about three years ago and have had them back several times since and have always been happy with the service."

Billie P.

"Had a wonderful experience with HEP. They were very informative and time effiecent with every job they came to out to do. Great prices to boot. We have used them on multiple projects ( heating, elective, and plumbing) and was never disappointed. Rick Hoe is an outstanding electrician and did an amazing job during our remodeling process. We feel at ease with all the new electrical changes that were made. Thanks HEP!!"

Courtney M.

"When matt& Alan came to the door, they were willing to service the customer. As the entire crew which were plumbing, electrical & remodeling. I will continue to be a loyal customer since 2006. The professional & respect shown to me was amazing. Hep is the place to go for a single woman."

Carol L.

"Josh and Adam are amazing! They went above and beyond for my mother in law helping with electrical issues that almost caused a house fire."

"Great personal interest in my situation and the solution to the problem. Rick, Will and Chris looked for the best HVAC system at the best price and backed it up with the best warranty. Top of the line quality Carrier! Thanks for the HEP! The sales guy, Rick Lounders, really knows his stuff. I worked in HVAC a while ago and he set me right on a couple of my ideas that would have been very wrong moves. I bought top of the line Carrier heat pumps and a very pleased. Also, the installers, Eddie Hawkins and Tim Sexton, and another guy - forget his name) were very sharp and the finish job looks VERY professional! They answered every question, showed me how everything worked, and cleaned up every scrap. They even wore booties to keep from getting leaves in the house - my wife was all about that. Use me as a reference or display job anytime! Thanks to Chris, too, for helping with the deal. Those Reme Halo UV lights are great. Kevin Stevens did a quick service call for a blown fuse, 4/4 - I was happy with the speed of response & checked everything over in detail. Very nice!"

TJ T.

Natalie P.

"Well waiting on another company and could not even get an estimate. Went ahead and called HEP! They made me an appointment for the next day and after the first HEP Rep came for the estimate ...Joe and Dart came the next day. These guys were great. Brought parts saw the problem immediately and included me in all the decisions and planning. Joe showed me the completed job when he and Dart were finished. PERFECT! I highly recommend HEP especially if you get Joe Brown and Dart Cremeans!! Thanks guys! Happy customer ....J"
