Furnace, Boiler & Heat Pump Service in Princeton
Princeton has a mix of newer homes with forced-air furnaces and older homes still heated by boilers and radiators. Our technicians are trained on both. We replace igniters, flame sensors, inducer motors, blower motors, gas valves and control boards on furnaces; circulators, zone valves, expansion tanks, low-water cutoffs and pressure controls on boilers; and reversing valves, defrost boards and compressors on heat pumps. No-heat calls are answered 24/7.
Serving Princeton and Mercer County
Princeton is a borough in Mercer County, and like most New Jersey boroughs it combines older homes near the center of town with later subdivisions on the edges, which means our technicians see everything from original boilers to builder-grade split systems installed in the last decade.
Mercer County ranges from Trenton rowhomes to Princeton colonials and newer developments in West Windsor, Robbinsville and Hamilton. We see a mix of gas furnaces, heat pumps and boilers, plus a lot of two-story homes that struggle to keep the second floor comfortable in July.
Although our headquarters is in Wanaque, our Central Jersey service team is based much closer to Princeton, and we schedule routes through Mercer County every week. See our Mercer County HVAC page for every town we cover nearby.
