Sizing a heat pump for Wallowa County starts with a problem that a spec sheet alone cannot solve. Homes in Wallowa County, OR run heat about ten months a year, from September through June. A heat pump's capacity drops as outdoor temperatures fall, and the coldest stretch of that heating season is precisely when the gap between what the equipment delivers and what the house demands grows widest. A contractor has to work out that gap before settling on equipment, because an undersized install will lean on its backup heat strips heavily and often. The load calculation here is the job.
Ductwork laid in for a furnace or a resistance system follows a logic built around that equipment: supply runs, return placements, and trunk sizing that a heat pump moves air through differently. Half the homes in Wallowa County, Oregon were built in 1973 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump installation here is pricing the duct layout as much as the unit itself, because what is already in the house may need modification before the new system can perform as it should. Electrical service is the second variable. Panels in houses of this vintage were not planned around the draw a heat pump puts on them, and an upgrade there can change the scope of the job before any equipment is ordered.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece most homeowners notice first. It sits on a pad beside the house and holds the compressor and the outdoor coil, which together do the core work of moving heat between the refrigerant and the outside air. Inside, the air handler mounts in a utility closet, attic, or basement and pushes conditioned air through the home.
A refrigerant line set runs between the two units, carrying refrigerant back and forth through insulated copper tubing. A thermostat goes on an interior wall and gives the homeowner control over the whole system. Both pieces are part of every standard installation.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house.
