Sizing a heat pump for Morris County starts with how hard and how long it has to work on the heating side. Homes in Morris County, NJ run heat about eight months a year, from October through May. Capacity in a heat pump drops as outdoor temperatures fall, so the coldest weeks of that run are what the contractor has to design around, not the average. A system undersized for those conditions will lean on its backup heat strip through the worst of winter, and that shifts the economics of the whole install. The contractor has to model the house's heat loss at design temperature before the equipment selection makes sense.
Ductwork laid out for a furnace and central air setup does not automatically carry a heat pump well. The supply and return paths, the trunk sizing, the register placement: all of it was designed around different airflow assumptions, and a contractor installing a heat pump has to assess each before the equipment choice is even final. Half the homes in Morris County, New Jersey were built in 1971 or earlier (2020-2024 ACS 5-year). That means a significant share of homes here have duct systems that may need rerouting, sealing, or resizing before a new unit can do its job. The electrical service is a separate question, and panels in houses of this vintage are often sized for a load that a heat pump's demands exceed.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first: a metal cabinet set on a pad beside the house that holds the compressor and the outdoor coil. Inside, an air handler mounts in a utility space, a closet, or an attic and moves conditioned air through the home. These two units are the heart of what a contractor puts in.
A refrigerant line set runs between the outdoor unit and the air handler, carrying the refrigerant that links the two sides of the system. A thermostat goes on an interior wall and gives the homeowner control over the whole setup. A condensate drain line also runs from the air handler to carry away any moisture the indoor coil pulls from the air.
The drawing shows the general layout of these components, and a licensed contractor determines exactly what applies to your house.
