Sizing a heat pump for Klamath County starts with how far outdoor temperatures drop in winter, because a heat pump's output falls as the air gets colder. Homes in Klamath County, OR run heat about ten months a year, from September through June. Through that stretch, the compressor, the reversing valve, and the defrost controls cycle repeatedly, and a system that enters the season undersized runs harder than it was built to. A contractor working the load calculation here has to establish what the house actually demands on the coldest nights, then decide what backup heat stage covers the gap a heat pump alone cannot close.
Ductwork sized and sealed for a furnace from a previous generation does not automatically carry what a heat pump needs. A contractor installing a heat pump here will pull register covers, measure static pressure, and look at trunk dimensions before pricing the equipment, because what is already in the walls decides whether the distribution system can do the job. Half the homes in Klamath County, Oregon were built in 1974 or earlier (2020-2024 ACS 5-year). That spread across the county's housing means a meaningful share of installs will turn on duct condition rather than equipment selection. The electrical service panel gets the same review, since a heat pump's draw is a different load than what many of these houses were originally wired to handle.
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 puts in place.
A refrigerant line set runs between the outdoor unit and the air handler, carrying the working fluid through both sides of the system. A thermostat goes on an interior wall where it can read the living space accurately, and a condensate drain line runs from the air handler to a suitable discharge point.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines exactly how each piece fits into your specific home.
