Sizing a heat pump for Lane County starts with what the heating season actually demands, not a generic Pacific Northwest estimate. Homes in Lane County, OR run heat about ten months a year, from September through June. As outdoor temperatures drop toward the cold end of that stretch, a heat pump's capacity falls, and a unit that looked adequate on paper starts leaning on its backup resistance heat more than it should. A contractor running a proper load calculation here accounts for that drop-off, so the installed system carries its own load through the coldest weeks rather than handing off to a strip heater. Getting the refrigerant charge and the coil match right at installation is what makes that capacity available when the season needs it.
Ductwork sized and routed for an older forced-air furnace often moves air in ways that work against a heat pump's lower-temperature, higher-volume delivery. Half the homes in Lane County, Oregon were built in 1977 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump in stock that age will open register runs, measure static pressure, and check whether the existing distribution can handle the airflow a heat pump needs before the equipment is even priced. Where it cannot, the duct modification is the job, and the unit itself follows from that.
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 are the core components of the system. Inside, the air handler mounts in a utility space, closet, or attic and moves conditioned air through the home.
A refrigerant line set runs between the two units, connecting the outdoor pad to the air handler and allowing the system to function as one. A thermostat goes on an interior wall where it reads the temperature of the living space and tells the system when to run.
The drawing shows a typical layout, and a licensed contractor determines exactly how each component is positioned and connected in your specific home.
