A heat pump's capacity drops as outdoor temperatures fall, and in a county where the heating load is as sustained as this one, a contractor has to run a full load calculation before settling on equipment size. Homes in Divide County, ND run heat about ten months a year, from September through June. Undersizing a heat pump for that kind of cold means the system runs at its limit through the hardest weeks, leaning on backup resistance heat and driving up operating costs the homeowner never budgeted for. The backup heat element, the refrigerant circuit, and the reversing valve all carry the consequences of a poor sizing decision. A contractor quoting work here sets the right equipment size first, then prices the unit.

Ductwork laid down for a furnace moves air at a different volume and pressure than a heat pump demands, and in stock as old as Divide County's, that original ductwork is still what is behind most walls. Half the homes in Divide County, North Dakota were built in 1963 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump installation here opens accessible duct runs first, checking whether the existing system can carry the new load or needs to be resized before the equipment question is even settled. The electrical service gets the same look: panels in houses this age were sized for a different draw, and a heat pump's requirements often land outside what the original service was built to handle.
What Goes Into a Heat Pump Installation

The outdoor unit sits on a pad beside the house and holds the compressor and the main coil. Inside, an air handler mounts in a utility space, a closet, or an attic and moves conditioned air through the home. These two units are what a new installation puts in place.
A refrigerant line set runs between the outdoor unit and the air handler, and a condensate drain carries moisture away from the indoor side. A thermostat goes on an interior wall where it reads 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 how each one is positioned and connected in your home.
