Step 1 of 3: Equipment

Ductwork laid out for a different era of equipment does not simply hand off to a heat pump. What a contractor finds behind the walls and under the floors reflects the choices made for whatever system came first, and those choices set the geometry a new installation either follows or fights. Half the homes in Aleutians West Census Area, Alaska were built in 1990 or earlier (2020-2024 ACS 5-year). That vintage of construction also means electrical service was planned around loads a heat pump was not part of, so a contractor scoping a job here checks the panel before pricing the unit.

What a Heat Pump Installation Puts in Your Home

The outdoor unit sits on a pad beside the house and holds the compressor and the heat exchange coil, which together do the core work of moving heat between outside air and the refrigerant lines. Inside, the air handler mounts in a utility space, attic, or closet and pushes conditioned air through the home. These two pieces are what a homeowner is buying when they commission a new system.

A refrigerant line set runs between the outdoor unit and the air handler, carrying refrigerant back and forth through insulated copper tubing. A thermostat mounts on an interior wall and gives the homeowner control over the whole system. A condensate drain line also runs from the air handler to a suitable discharge point, removing moisture pulled from indoor air.

The drawing alongside shows a representative layout, and a licensed contractor will determine exactly what applies to this house.
