Paula B.

"Called HEP to do repairs on my Carrier heating system. Joseph Sneed came out and diagnosed the problem which required ordering some parts. Joseph came back to today and after installing the parts he gave the unit a full check to make sure everything was in good working order. Joseph is very professional, and knowledgeable and absolutely takes pride in his work. When needed I will be calling HEP and asking for Joseph to do the work. Gene B."

Krystal G.

"Art and Chino installed our new HVAC System today and were very polite and helpful. We were very happy with their service."

Tobe R.

"We were pleased with everyone who took care of us. Efficient ,caring and polite people on the phone. Chase's service, Rick sales, and James and Tommy's installation were all first class. Our heat went out in the extreme cold. I called a HEP competitor first as many people told me they were cheaper. But the cheap service wouldn't come out and check for two days and installation would be five days after that. We had no heat! On the other hand, Chase from HEP came out and checked the day I called. Then Rick came over that same day to tell us our options. We took care of business and just over a day of finalizing had our heat. Tommy and James were great and the installation went quickly. Now someone will come out and check in two days that everything is working properly. It is. And twice yearly inspection is included in the price. We like the Carrier and you get what you pay for."

"Rick showed up within a couple hours to go over options for a new unit to heat out home. The unit was installed the next day. Everyone was friendly and knowledgeable. I would highly recommend HEP."

Larry N.

"Chase was very professional made me feel comfortable that I had made the right decision to choose Hep, then Gary was my 22nd contact, he too was knowledgable and very kind he and Chase had someone bring me w heaters because my house was so cold and I wouldn't have to leave my home before they started work the next morning. Thats when my next two contacts Ed and james arrived, they to were very profesdional and helpful, explained things to me where I could understand them, covered their feet before entering my home, also knocked before entering, cleaned up after themselves. It has been an overall very good experience dealing with hep, especially having to deal with such an expensive item day after Christmas. These 4 men represented Hep in a professional, knowledgeable hard working way. I highly recommend them and this company."
