What our customers say

Have used HEP services twice, plumbing and electric. Both repair men were prompt, cleaned up after the job, was pleasant to work with. Got good response/ turn around from the initial call until the job was finished. Even placed at call on Sunday evening. I have a maintance agreement that I pay yearly and plan to renew when it is time. It sure take's the work out of trying to find a reliable service provider.

Marcy G.

Our eleven-year-old heating and air conditioning system failed early in the Summer. We called HEP and after some discussion with their advisors we decided to invest in a state-of-the-art HVAC system manufactured by Trane and sold through HEP. It was installed quickly and efficiently and without delay by HEP service men. Part of the attraction was the Warranty offered by HEP which included a three-year-maintenance-and inspection-agreement on all household plumbing and electrical equipment, as well as a full ten-year-parts-and-labor Warranty on the HVAC system itself. Subsequently, we required service on our hot-tub and HEP's response ( from serviceman Richie) was quick, professional, and reasonable. We found him to be courteous and helpful. The problem turned out to be minor and we were only charged accordingly and fairly. We intend to continue to be HEP customers for all of our plumbing, electrical, and HVAC needs for the foreseeable future.
