Sizing a heat pump for this county is a local calculation, not a catalog lookup. Homes in Hood River County, OR run heat about ten months a year, from September through June. Through most of that run, the system operates in heating mode, where outdoor air temperature directly limits how much heat the unit can deliver. A contractor has to establish the heat loss of the house, the coldest design temperature the area sees, and whether back-up resistance heat is needed before the right equipment can be specified. An undersized unit will short-cycle or fall behind on the hard days, and the compressor carries the cost of that over years of repeated strain.
Existing ductwork is where a heat pump installation in Hood River County gets decided. Half the homes in Hood River County, Oregon were built in 1984 or earlier (2020-2024 ACS 5-year). Ductwork laid down for an older system carries different dimensions, different static pressure assumptions, and different routing than a heat pump wants. A contractor has to open, measure, and assess what is actually there before the equipment choice locks in. The electrical service gets the same scrutiny: a heat pump draws differently than whatever the panel was last sized to run.
What Gets Installed With a New Heat Pump
The outdoor unit sits on a concrete pad or wall bracket outside the house and holds the compressor and one set of coils. Inside, an air handler mounts in a utility space, closet, or attic and moves conditioned air through the home. These two units are the core of what a contractor places and connects.
A refrigerant line set runs between the outdoor unit and the air handler, carrying the working fluid that links the two. A thermostat goes on an interior wall where it can read the living space accurately and give the homeowner control over the system.
The drawing shows a representative layout, and a licensed contractor determines exactly how each piece fits the specifics of your house.
