Sizing a heat pump for Griggs County means working out how cold it actually gets, not just how long it stays cold. Homes in Griggs County, ND run heat about nine months a year, from September through May. A heat pump's capacity drops as outdoor temperatures fall, so a unit that covers the load on a mild February day can fall short on the hard days in January. The contractor has to establish the design temperature for this area and match the equipment to it, then spec backup heat for the gap that remains. Get that wrong and the resistance strips carry a disproportionate share of the season, running up bills and wearing out components the homeowner expected the heat pump to spare.
Ductwork laid down to move air for one generation of equipment does not automatically carry what a heat pump needs. Half the homes in Griggs County, North Dakota were built in 1958 or earlier (2020-2024 ACS 5-year). That history shows up in trunk sizes, in where runs terminate, and in whether the system as it stands can handle the distribution load a heat pump puts on it. A contractor pricing a heat pump installation here opens the duct layout before settling on equipment, because what is already in the walls decides what gets replaced alongside the unit.
What a Heat Pump Installation Puts in Your Home
The outdoor unit sits on a pad beside the house and holds the compressor and one set of coils. The indoor air handler mounts in a utility space, a closet, or an attic and moves conditioned air into the living areas. Together, those two units are the core of what a contractor installs.
A refrigerant line set runs between the outdoor unit and the air handler, carrying the working fluid that lets the two sides talk to each other. A thermostat goes on an interior wall where it reads the temperature of the living space and tells the system when to run.
The drawing shows the general layout of these components, and a licensed contractor determines exactly what applies to your house.
