Justin came out to my home on a Sunday to fix my air conditioner unit. The previous people I called to fix a blower motor made a lot of mistakes (Grissom Heat & Air) that caused a huge leak into my ceiling and he took the time to explain the mistakes that were made, and what needed to be done to fix them. I greatly appreciate Justin for taking the time to go over everything so I could understand it. He did a thorough job and I will definitely recommend Justin and HEP to anyone needing help with hvac or plumbing needs. Thank you!

So get this, I being a single parent decided it was appropriate to stop trying to do everything and hire the Smiley Face crew to tune my HVAC at the change of the season back in April'23. I haven't had working air since. Mainly because I was salty with the service and hadn't had the time to do it myself. Fast forward to June I've had enough of 80+ degrees and call Hep. Justin came through and went above and beyond what anyone could consider reasonable service. 5stars because he did everything the "Happy People" should have and then some. Better still it cost less!
