Sizing a heat pump for Orleans County starts with understanding what the equipment is actually asked to carry. Homes in Orleans County, NY run heat about eight months a year, from October through May. A heat pump's capacity drops as outdoor temperatures fall, and a unit sized for a mild stretch of that season will struggle when February arrives. The contractor has to run a load calculation against the coldest days, not the average ones, and decide where supplemental heat fits in. Get that wrong at installation and the backup resistance coils carry a load they were never meant to hold as a primary source.
The ductwork already in a house decides more about a heat pump installation than the equipment selection does. Half the homes in Orleans County, New York were built in 1955 or earlier (2020-2024 ACS 5-year). Houses built in that era were designed around furnaces and boilers, and the duct runs they got were sized for those systems, often too restrictive and too leaky to move the volumes of air a heat pump needs. A contractor quoting a job here has to walk the existing duct layout and measure what it will actually carry before any equipment choice is settled.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, mounted on a pad or bracket outside the house, and it holds the compressor and the outdoor coil that do the core work of the system. Inside, the air handler sits in a mechanical room, closet, or attic and circulates conditioned air through the home.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two through an exterior wall. The thermostat goes on an interior wall and gives the household control over the system. A condensate drain line carries moisture away from the air handler to a floor drain or outside.
The drawing shows a general layout of these components, and a licensed contractor determines exactly how each one is placed and connected in your house.
