Trudy G.

My heating and air unit completely quit on me the other day. I called HEP as they were the only ones who could come out on a moments notice. Unfortunately I had to get a whole new heating and air system (the writing was on the wall for some time, I was just waiting for the inevitable). I was financed the same day (at 8pm!!) and set up the installation. I was told it would take 6 to 8 hours estimate for the work to be done. The gentlemen that came to install the unit (Javi and Eric(?)) came on time and were very friendly and courteous and knowledgeable. They had the old system removed and the new one installed in just a little over 3 hours. I was all around very impressed with the work that was done...from the person that took my phone call the other day, to the technician that came out to diagnose the problem and helped me get financed and the gentlemen that installed the new system. Everyone was personable and knowledgeable throughout the whole process. I would definitely recommend HEP to anyone that is in need of home service that you can't do yourself.

David F.

Reuben was professional and thorough—I will ask for him again! He arrived to install and was thorough and quick’
