Sizing a heat pump for Bergen County starts with cold-end capacity, not average load. Homes in Bergen County, NJ run heat about eight months a year, from October through May. As outdoor temperatures fall through January and February, a heat pump's output drops while the house's demand rises, and the gap between those two lines is where backup heat lives. A contractor who skips a full load calculation and picks equipment by square footage alone leaves that gap wider than it needs to be. The homeowner pays for it every winter in resistance heat pulling full draw.
Ductwork in houses this old was designed around the system that came with the house, and a heat pump moves air at different volumes and pressures than what those runs were sized for. Half the homes in Bergen County, New Jersey were built in 1960 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump installation here measures and pressure-tests the existing duct system before anything else, because whether it can carry the new equipment without modification is what determines the scope and the price. The electrical service gets the same scrutiny: panels in houses of this vintage were not wired for the loads a modern heat pump draws.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece most homeowners notice first. It sits on a pad beside the house and holds the compressor and the outdoor coil, which together do the bulk of the work moving heat between inside and outside. The indoor air handler mounts in a utility space, closet, or attic and pushes conditioned air through the home.
A refrigerant line set runs between the two units, carrying the refrigerant that links them into a single system. The thermostat goes on an interior wall where it reads the home's temperature and tells the system when to run. A condensate drain line carries moisture away from the air handler.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house.
