Sizing a heat pump for Salem County means accounting for what happens to its output when outdoor temperatures fall hardest, because a system that looks adequate on paper can lean on its backup resistance heat for weeks at a stretch. Homes in Salem County, NJ run heat about seven months a year, from October through April. Contractors working an install here run a load calculation against the coldest part of that window, not the average of it, and the result shapes which unit gets spec'd and whether the existing service panel can carry it. A heat pump that clears winter with minimal backup heat saves real money on the electric bill; one that was undersized at installation runs resistance strips as a matter of routine.
Ductwork sized for a furnace and a central air conditioner carries air differently than a heat pump needs it to. Half the homes in Salem County, New Jersey were built in 1962 or earlier (2020-2024 ACS 5-year). That gap between what the house was built around and what a contractor is now being asked to put in it is where heat pump installation gets complicated in this county. A contractor has to measure static pressure, check duct condition, and decide whether what is already in the walls will carry the new system before anything gets priced or ordered.
What Gets Installed With a New Heat Pump
The outdoor unit sits on a pad beside the house and holds the compressor and the condenser coil. It is the largest piece a homeowner sees. Inside, the air handler mounts in a utility space, a closet, or an attic and pushes conditioned air through the home.
A refrigerant line set runs between the two units, carrying the working fluid through a pair of insulated copper lines that pass through the wall. A thermostat goes on an interior wall where it reads the temperature of the living space and tells the system when to run.
The drawing shows a representative layout, and a licensed contractor determines exactly how each piece fits the setup of your house.
