Sizing a heat pump for Richmond County is a local problem, not a catalog exercise. Homes in Richmond County, NY run heat about seven months a year, from October through April. Cold nights in January and February push a heat pump toward the bottom of its capacity curve, and a unit that is undersized for those conditions leans on electric resistance backup to close the gap. A contractor has to run a load calculation against the house's actual envelope before settling on a model, because a unit that works fine in October will struggle in February. Get that calculation wrong and the backup element carries the heating load through the hardest part of the winter.
Ductwork sized and routed for an older forced-air system handles air differently than a heat pump needs it to. Half the homes in Richmond County, New York were built in 1974 or earlier (2020-2024 ACS 5-year). A heat pump moves larger volumes of air at lower temperatures than a gas furnace does, and ducts laid out for the latter can create static pressure problems, uneven distribution, or noise that no amount of equipment adjustment will fix. A contractor quoting a heat pump here will open the supply and return trunks before pricing anything, because the duct layout is where the job either works or gets complicated.
What Gets Installed With a New Heat Pump
The outdoor unit sits on a pad beside the house and holds the compressor and coil that do the primary work of the system. Inside, an air handler or indoor unit mounts in a utility space, basement, or closet and moves conditioned air into the living areas. These two units are the core of what a contractor puts in.
A refrigerant line set runs between the outdoor and indoor units, connecting them through the wall or foundation. 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 carries moisture away from the indoor unit to a floor drain or outside.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house.

Heating and cooling loads are set by what the weather actually does in a given place, and a heat pump sized and installed for local conditions runs differently than one that was not. The record below shows what Richmond County has thrown at residential equipment over recent years.
