Sizing a heat pump for Northwest Hills means working out what the unit can actually deliver when outdoor temperatures bottom out, not just what it moves on a mild day. Homes in Northwest Hills Planning Region, CT run heat about eight months a year, from October through May. As temperatures fall, a heat pump's capacity falls with them, and a unit that tests fine in October may be handing off to backup resistance heat by January. A contractor quoting an install here has to run a full load calculation and specify a system whose rated output at low ambient temperatures still covers the house, or the homeowner pays for the shortfall in electricity every winter.
Ductwork laid for an oil furnace or an older central air system carries air at volumes and velocities that a heat pump does not match. A contractor installing a heat pump here has to assess what those ducts will actually do under the new load before anything else gets priced. Half the homes in Northwest Hills Planning Region, Connecticut were built in 1967 or earlier (2020-2024 ACS 5-year). That puts the existing duct layout at the front of the job, because retrofitting it once the new unit is already in costs more than accounting for it at the start.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, mounted on a concrete pad or brackets outside the house, and it holds the compressor and the refrigerant coil that do the system's core work. Inside, an air handler or fan coil sits in a utility closet, basement, or attic and moves conditioned air through the home.
A refrigerant line set runs between the two units, typically along an exterior wall or through a chase, carrying refrigerant back and forth to complete the loop. A thermostat goes on an interior wall and gives the homeowner control over the whole system.
The drawing shows a general layout of these components, and a licensed contractor determines exactly how each one is positioned and connected in your specific home.
