Sizing a heat pump for Clearwater County starts with what the climate actually asks of the equipment, not with a manufacturer's default range. 133 severe weather events were recorded in Clearwater County, Minnesota between 2015 and 2024. At that rate, severe weather is a standing condition here, which means a contractor quoting an installation has to account for sustained thermal load when selecting equipment and placing components. A unit undersized for what this area regularly puts on it will run hard and recover slowly. Getting the load calculation right before the equipment is ordered is where the install either holds up over time or does not.
Ductwork laid down for a furnace was sized, routed, and sealed for a different kind of airflow than a heat pump runs on. Half the homes in Clearwater County, Minnesota were built in 1980 or earlier (2020-2024 ACS 5-year). That gap between what the house already has and what a heat pump needs is where the real installation decision gets made. A contractor assessing the job has to look at duct cross-section, return-air capacity, and how the runs are laid out before the equipment choice means much. The electrical service gets the same scrutiny. Both determine the scope and the price before the heat pump itself is ever selected.
What a Heat Pump Installation Covers
The outdoor unit sits on a pad beside the house and holds the compressor and the condenser coil, which are the parts that do the heaviest work. Inside, the air handler mounts in a mechanical room, closet, or attic and pushes conditioned air through the home. Together these two cabinets are what a new installation puts in place.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two cabinets through an exterior wall. A thermostat goes on an interior wall where it reads the living space temperature and tells the system when to run. The condensate drain line carries moisture away from the air handler to a floor drain or outside.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house.

Licensing and Legal Requirements in Clearwater County, Minnesota
Minnesota defines a mechanical contractor as a business that installs, repairs or maintains heating, ventilating, cooling or refrigeration systems — the definition that carries the exemption from the residential contractor licence.
Minnesota's residential contractor licence does not reach HVAC work: the licensing section carries its own exemption list, and a mechanical contractor is exempt from the licence requirement by name.
