A contractor quoting a heat pump installation in Marion County has to nail the heating load calculation before anything else. Homes in Marion County, OR run heat about ten months a year, from September through June. That sustained demand is what pushes a heat pump toward its limits: capacity drops as outdoor temperatures fall, so a system sized to the middle of the range will struggle at the cold end of it. Backup resistance heat covers the gap, but only if it was specified and wired for it at install. A heat pump quoted without that cold-end analysis is set up to underperform from day one.
Existing ductwork and electrical service decide how a heat pump installation goes here, and both were built for something different from what a contractor is now quoting. Half the homes in Marion County, Oregon were built in 1979 or earlier (2020-2024 ACS 5-year). A house ducted for a gas furnace may move air at the wrong velocity for a heat pump's lower supply temperature, and a panel sized for the load of that era draws a hard line on what the new unit can draw. Those are the two questions a contractor opens before anything else gets priced.
What Gets Installed With a New Heat Pump
The outdoor unit sits on a pad beside the house and holds the compressor and the coil that exchange heat with the outside air. Inside, the air handler mounts in a utility closet, basement, 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 refrigerant that makes the exchange possible. A thermostat goes on an interior wall where it can read the home's temperature and signal both units to run or stop. A condensate drain line also ties into the air handler to carry off moisture the system pulls from indoor air.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece is positioned and connected in your home.
