Sizing a heat pump for Weston County is a question a contractor has to settle before anything else on the quote. Homes in Weston County, WY run heat about nine months a year, from September through May. That means the heat exchanger, the refrigerant circuit, and the backup heat source are all carrying a real load through most of a calendar year. A unit that falls short of the actual heating demand does not get a long summer break to recover; the compressor runs hard, cycling repeatedly in cold air that already strains its capacity. A contractor doing the load calculation has to account for how cold this area gets and match the equipment to that, not to a generic regional profile.

Ductwork sized for a furnace and a central air conditioner does not move air the same way a heat pump does, and in Weston County that gap between what the ducts were built for and what the new equipment needs is where most of the installation work actually lives. Half the homes in Weston County, Wyoming were built in 1974 or earlier (2020-2024 ACS 5-year). A contractor pricing a heat pump here has to pull sections of duct and measure what is there, because the original design decisions baked into those walls and ceilings determine whether the system will condition the house evenly or leave rooms short. The electrical panel gets the same scrutiny. What the house already has is the variable that sets the scope.

What Gets Installed With a New Heat Pump

The outdoor unit sits on a concrete pad beside the house and holds the compressor and one set of coils. Inside, the 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 during an installation.

A refrigerant line set runs between the outdoor unit and the air handler, carrying the working fluid through insulated copper tubing along the exterior wall and into the building. A thermostat goes on an interior wall where it reads the home's temperature and signals the system when to run.

The drawing shows a representative layout, and a licensed contractor determines what fits your specific house and how each piece gets positioned.
