Sizing a heat pump for Jackson County starts with what the climate actually asks of the equipment, and the local weather record is part of that calculation. 102 severe weather events were recorded in Jackson County, Wisconsin between 2015 and 2024. That puts severe weather in the category of a real and recurring factor, not a rare event, which means a contractor choosing equipment capacity and siting the outdoor unit has to build for a system that will meet genuine weather load across its service life. A heat pump spec'd as though the site were mild will run harder than it should, and the difference shows up in wear on the compressor and refrigerant lines long before it shows up on an energy bill.
Ductwork laid down for a furnace was sized around a different airflow pattern than a heat pump requires. Half the homes in Jackson County, Wisconsin were built in 1979 or earlier (2020-2024 ACS 5-year). A heat pump moves a larger, slower volume of air to deliver consistent temperatures, and ducts designed for a furnace's shorter, hotter bursts often run in layouts that fight that. A contractor quoting an installation here checks trunk sizes, branch routing, and return capacity before the outdoor unit enters the conversation. The electrical service gets the same scrutiny, since a heat pump's draw is steady where older wiring and panels were planned around intermittent loads.
What a Heat Pump Installation Covers
The outdoor unit sits on a pad beside the house and holds the compressor and the condenser coil, which are the core of the system. Inside, an air handler mounts in a utility space, a closet, or an attic and moves conditioned air through the home. These two units are the main equipment a contractor sets in place.
A refrigerant line set runs between the outdoor and indoor units, connecting the two and carrying the working fluid back and forth. A thermostat mounts on an interior wall and gives the homeowner control over the whole system. A condensate drain line runs from the air handler to a floor drain or outside, clearing the moisture the unit pulls from the air.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house.
