What Our Customers Say

"Chris K. came over to check our heating and air conditioning for a free initial test, he was great, he changed our filters and ran all the tests smoothly while letting us know throughout the appointment what he was doing and why. Great service!"

Kathryn F.

"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."

SUNNY S.

"My nest Stat went out and I tried to fix it myself but couldn’t figure it out. Called HEP and they gave me a time frame of 1:00pm-6:00pm same day. They called me back at 5:00pm to let me know it would be around 7:00pm. I was 2 days with no A/C so waiting an extra hour wasn’t really an issue for me. Steve showed up and gave me a solution to my problem within 20 minutes, but he also temporarily fixed my unit Until I could get a new thermostat unit because the stat I had was faulty. He also walked me through some basic maintenance I could perform to help my HVAC run smoothly. Steve was Professional, honest and friendly! Finding that trio is almost impossible this day and age. All in all Steve is the Bob Ross of professionalism and deserves recognition for his craft. Thank you!"

Scott H.

"Travis and Cody arrived on time with my new HVAC and quickly disassembled the old and removed it. They poured the new pad, set the new system, checked the ductwork, installed a new thermostat and were finished in 5 hours! They were great! I highly recommend this company. They show up! And they do what they say they are going to do. THANK YOU HEP!"

K C.

"The guys from HEP did a great job installing my Carrier HVAC unit. They took their time and made sure everything was done right. They asked me several times if I thought everything looked good throughout the install. There will be a inspection technician that will come out to do a follow-up to make sure the job was done properly, check the unit, and make sure the thermostat is working correctly. Everyone that I talked to from HEP was friendly and helpful. I would highly recommend using this company. Thank you for your service! Jody Technician came out the next day and checked the unit and all the work performed. All employees seem to care about the customers."

K9 N.

"Josh Crawford came by today for a spring inspection of our HVAC unit, and to help with some smart thermostat issues. He did a great and thorough job, and was very personable. He suggested we add a surge protector to our unit to protect our compressor, and made an excellent case for that without being pushy or applying undue sales pressure."

Tim M.

"I contracted with HEP to install a new HVAC system. The one they put in is an American Standard, which gets good ratings online. It is gas heat/electric air. Charlie and Avi removed the old unit, installed the new unit. got everything wired up, installed a new thermostat (old one was problematic), and hauled away the old HVAC unit. Very cool, very professional. I now have heat working correctly for the first time since March."

Wesley L.

"Replaced existing heat pump with a packaged Carrier. Cools very well and quiet. Price was competitive and included new digital thermostat, clean and sealed connection to house, concrete pad and 2 year free check ups. Install was completed as scheduled within 3 days of accepting their quote. Installers did great job. HEP was very responsive thru whole process. So far, no complaints."
