A contractor quoting heat pump repair here starts with the system's history, not the forecast. 92 severe weather events were recorded in Redwood County, Minnesota between 2015 and 2024. That puts this area in roughly the middle of the national range, which means severe weather is real but not the defining condition of every service call. A refrigerant leak or a failing reversing valve in a system that has run for years points first toward wear and how the unit was originally set up, and the weather record alone does not carry that diagnosis.
Ductwork in much of Redwood County's housing stock was laid down for heating systems that worked nothing like a heat pump, and the electrical feeding those spaces followed the same logic. Half the homes in Redwood County, Minnesota were built in 1965 or earlier (2020-2024 ACS 5-year). When a heat pump fails and a contractor opens the system, what they find in the walls and at the panel shapes how the repair goes as much as the failed component does. A refrigerant line that checks out fine can sit behind an air-distribution path that undercuts it. The repair bill reflects that, and so does the parts list.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is the piece most homeowners recognize: a metal cabinet that sits on a pad beside the house and holds the compressor and the outdoor coil. The compressor is the part contractors reach for first when a heat pump stops moving heat. A failed compressor, a refrigerant leak at the coil, or a seized fan motor in that cabinet will each kill the system in a different way, and the symptoms often look alike from inside the house.
The indoor air handler mounts in a closet, attic, or mechanical room and holds the indoor coil, the blower motor, and the expansion valve that controls refrigerant flow. A frozen indoor coil, a failing blower motor, or a stuck expansion valve can all cut airflow or make the system run without actually conditioning the air. The reversing valve, which sits inside the outdoor unit, is what lets a heat pump move heat in either direction, and a contractor checks it when the system heats but will not cool, or the other way around.
The drawing shows a typical layout, and a licensed contractor determines exactly which components apply to your house and system.

Licensing and Legal Requirements in Redwood 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.
Severe Weather Events in Redwood County
Extreme weather puts heat pumps under stress that routine operation never does. How hard the equipment works, and how often it fails, is tied directly to what the local climate delivers.
