Sizing a heat pump in Hubbard County starts with understanding what the equipment will run against year after year. 175 severe weather events were recorded in Hubbard County, Minnesota between 2015 and 2024. At that rate, severe weather is a standing feature of operating here, and a contractor who ignores it when selecting equipment capacity or choosing where to locate the outdoor unit is setting the system up to work harder than it was sized for. That means refrigerant line routing, unit placement, and equipment ratings all get decided with the local weather record in front of the contractor, not after the box is already on the wall.
Ductwork sized for a furnace and electrical service wired before heat pumps were common are what a contractor runs into here more often than not. Half the homes in Hubbard County, Minnesota were built in 1985 or earlier (2020-2024 ACS 5-year). That matters for installation because a heat pump moves air at lower temperatures and higher volumes than the system that ductwork was designed around, so a contractor has to assess whether the existing runs and returns can handle it before any equipment gets ordered. The electrical service gets the same scrutiny, since a heat pump's draw is different from what older panels were set up to feed.
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 coil that exchange heat with the outside air. The indoor air handler mounts inside, often in a utility closet, attic, or basement, and moves conditioned air through the home. Together these two units are what a heat pump installation adds to the structure.
A refrigerant line set runs between the outdoor and indoor units, carrying refrigerant back and forth through insulated copper tubing. A thermostat, mounted on an interior wall, is the control point where the homeowner sets temperatures and, on many modern systems, schedules.
The drawing shows a representative layout, and a licensed contractor determines exactly how each piece is positioned and connected in your specific home.

Licensing and Legal Requirements in Hubbard 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 Hubbard County
Weather extremes put a direct load on heating and cooling equipment, and that load shapes which heat pump a contractor selects and how they size it. What happens in this county is the starting point for that decision.
