A contractor quoting a heat pump installation in Oconto County has to size for what this area actually puts a system through, not for a catalog average. 119 severe weather events were recorded in Oconto County, Wisconsin between 2015 and 2024. At that rate, severe weather is part of the normal operating life of any system installed here, which means the refrigerant circuit, the compressor ratings, and the mounting and weatherproofing details all get weighed against sustained local load rather than mild baseline assumptions. A unit sized for somewhere easier will be undersized here.
Ductwork laid down for a furnace was sized around high-temperature air moving in short bursts. A heat pump moves more air at lower temperatures, and ducts that worked fine for decades can be too narrow, too leaky, or routed in ways that strangle the new system before it runs its first cycle. Half the homes in Oconto County, Wisconsin were built in 1981 or earlier (2020-2024 ACS 5-year). That means a contractor evaluating an installation here has to assess the existing duct layout, not just the equipment going in. Electrical service gets the same look, since a heat pump's draw is different from what older panels were wired to handle.
What a Heat Pump Installation Covers
The outdoor unit is the piece a homeowner sees first: a metal cabinet set on a pad beside the house, housing the compressor and the coil that exchange heat with the outside air. Inside, an air handler or indoor coil sits in the utility space or attic and moves conditioned air through the home.
A refrigerant line set runs between the two units, connecting the outdoor cabinet to the indoor equipment through the wall or roof penetration. A thermostat goes on an interior wall and gives the homeowner control over the whole system.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house.

Licensing and Legal Requirements in Oconto County, Wisconsin
A Wisconsin business that employs a certified HVAC qualifier is a certified HVAC business, and no city or county may require it to hold a local certification or licence on top of that.
Wisconsin requires a state HVAC contractor registration: no person or business may install or service heating, ventilating or air conditioning equipment, or offer to, without one.
Severe Weather Events in Oconto County
Heating and cooling loads are shaped by what the local climate actually does, not what an average suggests. A heat pump sized and installed for the weather patterns here will run differently than one installed two counties over, which is why local weather history belongs in any honest conversation about equipment.
