Annandale is a community within Clinton Township in central Hunterdon County, surrounded by the scenic hills and open farmland of western New Jersey. The area sits near landmarks like the Spruce Run Reservoir and Round Valley Reservoir, popular destinations that reflect the natural character of the region. Homes in Annandale range from older farmhouses and historic properties to suburban-style neighborhoods, many of which rely on boilers, oil furnaces, and aging central AC systems that require knowledgeable technicians — not cookie-cutter HVAC solutions.
