Sizing a heat pump for Orange County is a local problem, not a catalog selection. Homes in Orange County, NY run heat about eight months a year, from October through May. A heat pump loses heating capacity as outdoor temperatures fall, so the coldest weeks of that stretch are exactly when the system is working hardest and delivering the least. A contractor has to establish what the house actually needs at the design low before specifying equipment, and back-up heat is part of that calculation. Undersizing shows up fast under those conditions.
Ductwork laid down for a furnace or a central air system of an earlier era was designed around that equipment's airflow and return requirements, and a heat pump runs differently enough that what is already in the walls and ceilings sets the terms of the job before any unit gets selected. Half the homes in Orange County, New York were built in 1975 or earlier (2020-2024 ACS 5-year). A contractor pricing a heat pump installation here measures duct capacity and checks the electrical service panel before specifying equipment, because those two things, not the unit on the truck, are what determine what the job actually costs and how it is done.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, mounted on a pad or brackets outside the house, and it holds the compressor and the main coil that pulls heat from the air. Inside, an air handler sits in a utility space, closet, or basement and moves conditioned air through the home. Together these two units are what a heat pump installation puts in place.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two through an exterior wall. A thermostat goes on an interior wall where it reads the home's temperature and tells the system when to run. A condensate drain line also gets routed from the air handler to carry away moisture the coil pulls from indoor air.
