"Hillside Heating & Cooling/Oil Co. is outstanding and is a first-rate company. Removal of an old heating system and installation of a heat pump/ AC and installation of a natural gas tankless water heater was done in one day with two crews. The technicians worked as a team to do the job and were respectful of our property. In over 60 years of dealing with heating companies, we were most impressed with Hillside and everyone from the company that we dealt with. Thanks to Jerry for setting it up. This is a quality company. "
