A contractor sizing or installing a heat pump in Crawford County is working with a weather record that falls well short of demanding. 71 severe weather events were recorded in Crawford County, Wisconsin between 2015 and 2024. Severe weather is an occasional event here rather than a standing condition, which means the equipment a contractor encounters has not been ground down by relentless load. That shifts the real sizing questions toward the house: insulation, air sealing, duct layout, and how the building actually holds temperature on the coldest nights. A system installed without attention to those details will underperform regardless of what the sky has done.
Ductwork laid in for a gas furnace carries air at different volumes and velocities than a heat pump requires, and a house with that original ductwork may need sections rebalanced, resized, or replaced before the new unit can perform correctly. Half the homes in Crawford County, Wisconsin were built in 1978 or earlier (2020-2024 ACS 5-year). That age of construction also means the electrical service was designed around equipment with different draw characteristics, so a contractor will check the panel before the heat pump goes in. What they find in the ducts and at the panel, not the equipment choice itself, is what sets the scope and the price of the job.
What a Heat Pump Installation Covers
The outdoor unit is the piece most homeowners notice first. It sits on a pad outside the house and holds the compressor and the coil that exchange heat with the outside air. Inside, the air handler mounts in a utility space, closet, or attic and moves conditioned air through the home.
A refrigerant line set runs between the two units, connecting the outdoor and indoor sides of the system. A thermostat goes on an interior wall where it reads the home's temperature and tells the system when to run. Both pieces are part of what a contractor installs alongside the main equipment.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house and its existing setup.

Severe Weather Events in Crawford County
Heating and cooling loads are shaped by the conditions a place actually sees, not averages. A heat pump sized and installed for Crawford County's weather pattern works differently than one built for somewhere else, which is why local weather history belongs alongside installation decisions.
