Sizing a heat pump for this address starts with what the heating season asks of it. Homes in Essex County, NJ run heat about eight months a year, from October through May. A heat pump's output drops as outdoor temperatures fall, so a contractor has to work out where that curve crosses the house's actual heat loss before they can quote a system that covers the load. Undersizing shows up first on the hardest nights of a long winter, not on a mild afternoon. The back-up heat decision follows directly from that calculation, and getting it wrong costs a homeowner more to fix later than it cost to skip.
Ductwork laid down for a furnace and window units was sized, routed, and sealed for a completely different kind of load than a heat pump puts on it. Half the homes in Essex County, New Jersey were built in 1958 or earlier (2020-2024 ACS 5-year). That gap between what was built in and what a contractor is now asked to connect is where an installation job either stays simple or gets complicated fast. Before any equipment gets priced, a contractor walks the ductwork to see whether it can move the air a heat pump needs moved, and whether the electrical service will carry the draw.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, mounted on a concrete pad or wall bracket outside the house, and it contains the compressor and the coil that exchange heat with the outside air. Inside, the air handler sits in a closet, utility room, or attic and pushes conditioned air through the home.
A refrigerant line set runs between the two units, carrying the fluid that links the outdoor and indoor sides of the system. A thermostat goes on an interior wall and gives the homeowner control over the whole setup.
The drawing shows the general layout of these components, and a licensed contractor determines exactly how they fit the specific conditions of your house.
