A contractor quoting a heat pump install in Lincoln County has to work out what the system will be running against before settling on a unit size or a refrigerant line configuration. 99 severe weather events were recorded in Lincoln County, Wisconsin between 2015 and 2024. That puts the county squarely in the middle of the national distribution for severe weather, which means neither an oversized buffer nor a stripped-down spec is the automatic answer. The right size comes from what this site demands, not from what a catalog lists as standard for a Wisconsin address.
Ductwork sized for an older furnace carries different airflow assumptions than a heat pump needs, and in a county where much of the housing stock predates the equipment now running in it, that gap is where a heat pump installation gets complicated or stays simple. Half the homes in Lincoln County, Wisconsin were built in 1975 or earlier (2020-2024 ACS 5-year). A contractor scoping a job in a house of that vintage has to look at what the existing duct runs can actually move before the new unit is selected, because the electrical service also reflects what the house was built for. Both can be adapted. Neither can be skipped.
What a Heat Pump Installation Puts in Your Home
The outdoor unit sits on a pad beside the house and holds the compressor and coil that do the heaviest work. Inside, an air handler mounts in a utility space, basement, or closet and pushes conditioned air through the home. These two pieces are the core of what a contractor sets in place.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two through an exterior wall. A thermostat goes on an interior wall where it reads the living space and tells the system when to run. Some installs also include a supplemental heat strip inside the air handler for the coldest periods.
The drawing shows a typical layout, and a licensed contractor determines exactly what your house requires.
