Sizing a heat pump for Power County is a local calculation, not a catalog pick. Homes in Power County, ID run heat about ten months a year, from September through June. Cold outdoor air cuts into a heat pump's capacity exactly when demand is highest, so a contractor has to establish what the coldest nights here actually ask of the equipment before settling on a unit. A system that falls short on those nights runs its backup resistance heat heavily, which the compressor and the rest of the refrigerant circuit were not sized to offset. Getting the load calculation right at install is what keeps that from happening.
Ductwork put in for a furnace and window units carries different dimensions, routing, and return-air assumptions than a heat pump system needs. Half the homes in Power County, Idaho were built in 1975 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump installation here is not just pricing the new unit; they are measuring what is already in the walls to decide whether it carries the new load or has to be reworked. The electrical service is the same question. Service panels in houses of this vintage were sized for a different draw, and a heat pump's demand often lands outside what that panel was built to handle.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, mounted on a pad beside the house, and it holds the compressor and the outdoor coil. Inside, an air handler sits in a utility space, basement, or closet and circulates conditioned air through the home. Together these two units are the core of what a contractor sets in place.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two through an exterior wall. A thermostat goes on an interior wall where it can read the living space, and a condensate drain line runs from the air handler to a suitable discharge point. These are the remaining pieces a contractor places during a heat pump installation.
