Sizing a heat pump in Kenosha County starts with what the climate actually demands of the equipment, not with what a catalog suggests for a generic Wisconsin address. 82 severe weather events were recorded in Kenosha County, Wisconsin between 2015 and 2024. At that rate, severe weather is a standing feature of operating conditions here, not an occasional outlier, and a contractor who ignores it will undersize the system or skip protections the load warrants. The refrigerant line set, the electrical supply, and the mounting all get specified against what this area runs against, not against a regional average.
Existing ductwork is what shapes a heat pump installation in Kenosha County more than anything else a contractor will price or plan around. Half the homes in Kenosha County, Wisconsin were built in 1975 or earlier (2020-2024 ACS 5-year). Houses built in that era were ducted for furnaces, which move heated air differently than a heat pump does, and what works for one does not automatically carry the other. Before a new unit goes in, a contractor has to assess whether the existing duct system handles the air volume and static pressure a heat pump demands. Electrical service gets the same look. The equipment selection happens after those answers.
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 exchanges heat with the outside air. Inside, the air handler mounts in a utility space, closet, or attic and moves conditioned air through the home. These two units are what a contractor sets in place.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two halves of the system through the wall or floor. A thermostat goes on an interior wall where it can read the home's air and signal the system when to run.
The drawing shows a typical layout, and a licensed contractor determines exactly how the system comes together in your house.

Severe Weather Events in Kenosha County
Weather puts a measurable load on heating and cooling equipment, and that load is shaped by local conditions. A heat pump sized and installed for what Kenosha County actually experiences will run differently than one spec'd from a national average.
