A contractor quoting a heat pump installation in Grant County has to account for what the climate regularly asks of the equipment, because severe weather here shows up often enough to be part of the baseline, not an outlier. 135 severe weather events were recorded in Grant County, West Virginia between 2015 and 2024. At that rate, the load assumptions baked into a standard residential heat pump spec can underserve this area, and a contractor who sizes by catalog alone leaves the system working harder than it was built to sustain. Getting the equipment right from the start means treating local weather as a design condition.
Ductwork laid down for an older heating system was sized, routed, and sealed for different airflow demands than a heat pump puts on it. Half the homes in Grant County, West Virginia were built in 1980 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump installation here opens walls and crawlspaces to check what is actually there, because the original ductwork may handle the new load or it may not, and the quote changes accordingly. Electrical service follows the same logic: what the panel was built to carry gets measured, not assumed.
What Gets Installed With a New Heat Pump
The outdoor unit sits on a pad beside the house and holds the compressor and condenser coil, the two components that do the bulk of the work. Inside, the air handler mounts in a utility space, basement, or closet and moves conditioned air through the home. These are the pieces a homeowner sees and lives with.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two halves of the system through the wall or floor. A thermostat goes on an interior wall where it can read the living space accurately and give the homeowner control over the whole system.

Severe Weather Events in Grant County
Extreme weather puts heat pump systems under load they were sized to handle, and Grant County conditions shape what that load looks like year to year. Knowing the local pattern helps a contractor specify equipment that fits the actual climate, not a generic one.
