What our customers say

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.

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!
