A contractor quoting a heat pump install in Racine County starts with sizing, and the climate record is part of what drives that calculation. 98 severe weather events were recorded in Racine County, Wisconsin between 2015 and 2024. At that rate, severe weather is a standing feature of the operating environment, which means a system sized for average conditions gets put under real load on a regular basis. Undersizing a cold-climate heat pump here shows up as a system that runs constantly and still falls short during the stretches that matter most. Contractors working in this county factor that load into equipment selection before anything else on the spec sheet.
Ductwork laid down for a furnace was sized and routed for a furnace. Half the homes in Racine County, Wisconsin were built in 1968 or earlier (2020-2024 ACS 5-year). A heat pump moves air differently, and what a contractor finds inside the walls and ceilings of a house that old determines whether the existing duct system carries the new load or needs to be reworked before the unit goes in. Electrical service gets the same look: the panel has to support what a heat pump draws, and in housing of this vintage that is not always a given. The ductwork assessment shapes the quote.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, mounted on a concrete pad or wall bracket beside the house, holding the compressor and one set of coils. The indoor air handler goes inside, most often in a utility closet, basement, or attic, and it is where conditioned air gets pushed into the home's supply ducts.
A refrigerant line set runs between the two units, carrying refrigerant through insulated copper tubing that passes through an exterior wall. The thermostat, mounted on an interior wall, is what ties both units together and gives the homeowner control over the whole system.
