100% rating by L.D. from Newark, DE on 01/05/23"Every time someone has come, they’ve been very courteous and responsive. I’m sorry I’ve forgotten the name of the young man who came yesterday, but in addition to doing the annual check of my furnace, he inserted the new filter into the blower for me (which I had setting there ready to insert)."

100% rating by J.B. from Newark, DE on 01/05/23"Once again Hillside Heating gave me outstanding service. During the recent cold snap (temps around 5 degrees with -13 windchill), my 2-yo furnace (recommended and installed by another provider) couldn’t keep up. Mike, the Hillside tech, thoroughly checked out the system. He found problems with the settings and improper vent positions throughout the house — careless work by the former vendor. In a couple of hours, the system was working much better with every room feeling comfortable and cozy. Thank you Mike and Hillside!"

100% rating by M.G. from Wilmington, DE on 12/30/22"Thank you very much for responding quickly. I'm very satisfied with you and Tom. He was very professional and understanding. Of course, my thermostat went blank and Tom had me check the batteries and sure enough, that's what was wrong. A fluke! Thank you, again."

Hillside was professional the person who answered the phone seemed to be very knowledgeable I really like the overall service."

100% rating by T.D. from Claymont, DE on 12/22/22"Excellent service. John took the time to diagnose the problem and consulted with another technician regarding what he found with our furnace.
