Sizing a heat pump for Klickitat County is not a question a contractor answers from a catalog. Homes in Klickitat County, WA run heat about ten months a year, from September through June. As outdoor temperatures fall through those months, a heat pump's output falls with them, so a system sized for a mild winter day leaves the house short on the coldest ones. A contractor has to establish the building's actual load and the coldest temperatures the site sees before the equipment can be specified correctly. Back-up heat is a local decision too, and one that gets locked in at installation.
Ductwork sized for an older system and a service panel wired to an earlier load are the two things a contractor has to evaluate before a heat pump installation in Klickitat County can be quoted accurately. Half the homes in Klickitat County, Washington were built in 1986 or earlier (2020-2024 ACS 5-year). That age of construction means the ducts and the electrical came in together, sized for whatever was running then. A contractor who skips opening and measuring both before pricing the unit is guessing at the job's actual scope.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, mounted on a concrete pad beside the house, housing the compressor and the coil that exchange heat with the outside air. Inside, the air handler sits in a utility closet, basement, or attic and moves conditioned air through the home. 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, carrying the working fluid that connects the two sides of the system. The thermostat goes on an interior wall where it reads the home's temperature and signals the system to run. A disconnect box lands near the outdoor unit to give the contractor a local shutoff point.
The drawing beside this text shows a typical layout, and a licensed contractor determines exactly how each piece fits the specifics of your home.
