A contractor quoting a heat pump install in Eau Claire County has to account for what the system will run against year after year, not just what the catalog recommends for a house of that square footage. 88 severe weather events were recorded in Eau Claire County, Wisconsin between 2015 and 2024. At that rate, severe weather is a standing part of normal operation here, which means sizing, refrigerant line placement, and the integrity of every exterior penetration carry more weight than they would somewhere the equipment rarely gets pushed hard. A unit that fits the load on a calm day can still be wrong for this location if the install does not account for what stress does to efficiency and sealing over time.
Ductwork laid out for a furnace and central air system carries air differently than a heat pump needs it to. Half the homes in Eau Claire County, Wisconsin were built in 1978 or earlier (2020-2024 ACS 5-year). A contractor installing a heat pump in a house from that period has to assess whether existing duct runs, their sizing, and their sealing can handle the distribution requirements of the new equipment before anything else gets priced. Electrical service in houses of that age is the second variable: heat pumps draw on dedicated circuits, and what is already in the panel determines whether that is a straightforward connection or a separate job.
What a Heat Pump Installation Covers
The outdoor unit is the piece most homeowners see first. It sits on a pad beside the house and holds the compressor and the coil that exchange heat with the outside air. Inside, the air handler mounts in a utility space, closet, or attic and moves conditioned air through the home.
A refrigerant line set runs between the two units, connecting the outdoor and indoor sides of the system. A thermostat goes on an interior wall and gives the homeowner control over the whole setup. Some installations also include a supplemental heating element inside the air handler for the coldest days.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house.
