Serving Sussex and Sussex County
Sussex is a borough in Sussex 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.
Sussex County is the coldest corner of the state, with lake communities, farms and wooded lots from Vernon down to Byram. Propane and oil heat remain common, winter design temperatures are lower than the rest of New Jersey, and cold-climate heat pumps have become a popular upgrade.
Sussex is under an hour from our Wanaque headquarters, and our North Jersey technicians cover it daily for emergency and scheduled calls. See our Sussex County HVAC page for every town we cover nearby.
