Sizing a heat pump for Churchill County starts with how far outdoor temperatures drop and how long they stay there, because a heat pump's capacity falls as the cold deepens. Homes in Churchill County, NV run heat about eight months a year, from October through May. Through those months, the compressor cycles on and off across conditions that test the low end of its rated capacity, and the refrigerant circuit, the reversing valve, and the defrost controls all carry real accumulated load. A contractor who skips a full load calculation and defaults to the previous unit's tonnage leaves the homeowner depending on expensive backup resistance heat to close the gap the undersized system cannot.

Ductwork laid down for a furnace and window units does not automatically carry a heat pump. Half the homes in Churchill County, Nevada were built in 1990 or earlier (2020-2024 ACS 5-year). A contractor pricing an installation here opens walls and crawl spaces to find out what the existing runs will actually move and where the supply and return air goes, because a system configured for one kind of heating loads the ducts differently than a heat pump does. The electrical panel gets the same look: what the original service was sized for and what a heat pump draws are two different numbers, and the panel either handles it or it does not.
What Gets Installed With a New Heat Pump

The outdoor unit is the piece most homeowners see first. It sits on a pad beside the house and holds the compressor and the outdoor coil, which together do the work of moving heat in or out depending on the season. Inside, the air handler mounts in a utility closet, attic, or basement and pushes conditioned air through the home.
A refrigerant line set runs between the two units, carrying the refrigerant that connects the outdoor and indoor sides into one system. A thermostat goes on an interior wall where it reads the air temperature and tells the system when to run.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house.
