A heat pump contractor sizing a system in Yellow Medicine County is not working around an extreme climate. 91 severe weather events were recorded in Yellow Medicine County, Minnesota between 2015 and 2024. At that rate, severe weather is a real but ordinary feature of operating here, and it does not by itself determine whether a system runs well or fails early. The install does. A unit that is correctly sized for this county's heating and cooling demands, properly charged, and sealed against the cold will outperform an oversized one dropped in without attention to the envelope, regardless of the season outside.
Ductwork laid in for a furnace follows a different logic than what a heat pump needs, and in Yellow Medicine County much of it has been doing that job for a long time. Half the homes in Yellow Medicine County, Minnesota were built in 1958 or earlier (2020-2024 ACS 5-year). Contractors sizing a new heat pump here open walls and crawlspaces to find duct runs that were never intended for the load a heat pump places on them, and what they find determines whether the installation is straightforward or requires rebalancing the system before the new unit goes in. The electrical service is a separate check, but the ductwork is where the job's scope gets settled.
What a Heat Pump Installation Covers
The outdoor unit sits on a pad beside the house and holds the compressor and the coil that exchange heat with the outside air. Inside, the air handler mounts in a mechanical room, closet, or attic and moves conditioned air through the home. These two units are the core of what a contractor puts in place.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two through a wall or ceiling chase. A thermostat goes on an interior wall where it can read the living space accurately and give the homeowner control over the system.
The drawing shows the general layout of these components, and a licensed contractor determines exactly how they apply to your house.

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.
