A heat pump's capacity falls as the outdoor air gets colder, which makes the sizing question here sharper than it is in milder climates. Homes in McHenry County, ND run heat about nine months a year, from September through May. A contractor quoting this job has to work out what the equipment is being asked to do at the coldest point of that run, then decide whether supplemental heat is part of the answer or whether the primary unit can carry the load alone. Get that calculation wrong at installation and the homeowner discovers the gap on a January night, not during a milder stretch where the equipment can mask an undersized choice.
Ductwork laid out around a furnace has a specific logic to it, and a heat pump does not share that logic. Half the homes in McHenry County, North Dakota were built in 1966 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump installation here measures what the existing runs can actually move, not just whether they are present, because the answer changes the scope and the price before any equipment gets ordered. Electrical service gets the same look: a panel sized for what the house originally ran may need an upgrade to carry the new unit's load.
What a Heat Pump Installation Puts in Your Home
The outdoor unit sits on a pad beside the house and holds the compressor and the heat exchanger coil that face the outside air. The indoor air handler mounts inside, usually in a utility room or basement, and moves conditioned air through the home. Together these two units are the core of what a contractor sets in place.
A refrigerant line set runs between the outdoor and indoor units, carrying the working fluid that ties the two sides together. A thermostat mounts on an interior wall and gives the homeowner control over the whole system. Where a home already has a furnace, the air handler connects to that existing equipment instead of standing alone.
The drawing shows a typical layout, and a licensed contractor determines exactly how the components fit the conditions of your specific house.
