Sizing a heat pump for Washakie County means working out what happens at the cold end of the season, not just the average of it. Homes in Washakie County, WY run heat about nine months a year, from September through May. A heat pump's capacity drops as outdoor temperatures fall, so a unit that handles October comfortably may lean hard on its backup resistance elements through January and February. Contractors have to run a full load calculation against the local temperature range before they can specify the right equipment. An undersized unit does not simply struggle; it shifts load onto resistance heat, which runs at a fraction of the efficiency the heat pump was installed to deliver.
Ductwork laid when a house was built does not always carry what gets connected to it later. Half the homes in Washakie County, Wyoming were built in 1972 or earlier (2020-2024 ACS 5-year). That gap between the original construction and the system a contractor is installing today shows up in duct runs that were sized for different equipment and electrical service that may not meet the load a heat pump draws. A contractor has to confirm both before the new unit can be quoted, because a duct system that restricts airflow will undermine the equipment regardless of what gets ordered.
What Gets Installed With a New Heat Pump
The outdoor unit sits on a pad beside the house and holds the compressor and coil that do the system's core work. Inside, the air handler mounts in a utility space, basement, or closet and moves conditioned air through the home. These two units are the heart of what a contractor puts in place.
A refrigerant line set runs between the outdoor unit and the air handler, carrying the working fluid that lets the two sides of the system exchange heat. A thermostat goes on an interior wall where it can read the living space and signal the system to run. Both pieces are part of what gets placed and connected during installation.
The drawing shows the general layout of these components, and a licensed contractor determines what applies to your specific house and setup.

Heating and cooling loads are not abstract figures. They follow what the sky does, and in Washakie County that means a heat pump sized and installed for local conditions carries a different burden than one dropped in from a catalog. The chart below tracks recorded severe weather events in the county, year by year, because that record shapes what the equipment has to handle.
