HEP won the low bid on a series of HVAC installs. One of which was in the house that I rent. Having been the low bid, I was expecting HEP to be cutting corners at every opportunity. But to my surprise, they worked on the install as if they were working on their own homes. Careful attention was made to detail and no corners cut. I was pleasantly surprised. I had recently sold a Condo in Louisiana before moving to Tennessee. It had a cheap HVAC system. So I know what one looks like. The system the HEP installers installed here was not one. A lot of time was taken to install it correctly. Jeremy, Ronnie and Aavi were expert installers. I highly recommend HEP for an HVAC system. You'll get a competitive price for a system expertly installed.
