Sizing a heat pump for Pierce County means working from what the heating load actually is, not from what a generic table suggests. Homes in Pierce County, ND run heat about nine months a year, from September through May. A heat pump loses capacity as outdoor temperatures fall, so a unit that tests well in mild weather can fall short when the season deepens and the compressor is already cycling hard. A contractor has to establish the balance point for this house before they can specify the right equipment or decide what backup heat is needed. Get that wrong and the resistance strips carry load the refrigerant circuit was built to handle.

Ductwork that has never been asked to carry a heat pump is the first thing a contractor has to assess in Pierce County. Half the homes in Pierce County, North Dakota were built in 1972 or earlier (2020-2024 ACS 5-year). That stock was built around equipment with different airflow demands, and the duct runs designed for it often run too small, too leaky, or through spaces that complicate any retrofit. Electrical service is a related question: panels in houses of that vintage were sized for loads that did not include a heat pump. What a contractor finds in both places determines the real scope of the job before the unit itself is even priced.
What a Heat Pump Installation Puts in Your Home

The outdoor unit is the piece most homeowners see first. It sits on a pad beside the house and holds the compressor and the outdoor coil, which together do the heavy lifting of moving heat between outside air and the refrigerant. Inside, the air handler mounts in a utility space, attic, or closet and pushes conditioned air through the home.
A refrigerant line set runs between the two units, connecting the outdoor and indoor sides through the wall or floor. A thermostat goes on an interior wall where it reads the living space and tells the system when to run.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the specifics of your house.
