Sizing a heat pump for Garfield County means accounting for what outdoor temperatures do to its capacity, not just what the house needs on a mild October afternoon. Homes in Garfield County, UT run heat about eight months a year, from October through May. As temperatures drop through January and February, the refrigerant circuit moves less heat per cycle, and a system that was marginal on paper becomes one that leans on its backup resistance coil to cover the shortfall. A contractor running a proper load calculation here has to establish both the heat pump's rated output and its cold-weather derating before the quote means anything.
Existing ductwork is what a contractor prices hardest on a heat pump job here. Half the homes in Garfield County, Utah were built in 1982 or earlier (2020-2024 ACS 5-year). Duct systems put in for earlier equipment were laid out around different airflow assumptions, and a heat pump runs at lower supply temperatures with longer cycles, which exposes leaks and undersized runs that an older furnace would mask. Electrical service gets checked too, but ductwork is where the scope can shift.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, mounted on a pad beside the house, and it holds the compressor and the outdoor coil that do the system's core work. Inside, an air handler sits in a closet, attic, or mechanical room and pushes conditioned air through the home.
A refrigerant line set runs between the two units, connecting the outdoor pad to the air handler through the wall or ceiling. A thermostat goes on an interior wall and gives the homeowner direct control over the whole system.
The drawing shows a representative layout, and a licensed contractor determines what the installation requires for this particular house.

Licensing and Legal Requirements in Garfield County, Utah
Utah’s contractor licence does not reach alteration, repair, remodelling or improvement of a building worth less than $7,000 in labour and materials together, counting every change and addition to the agreed work — though the plumbing and electrical trades are pulled back under licensure even below that figure.

Severe Weather Events in Garfield County
Weather patterns shape how hard a heat pump has to work, and how hard it works shapes what it needs to be. Sizing and installing equipment without accounting for local conditions is how systems end up undersized, oversized, or wrong for the place.
