A contractor quoting a heat pump installation in Craig County has to size the system to what the local climate actually demands, and that means working from real load calculations rather than guessing from house size alone. 47 severe weather events were recorded in Craig County, Virginia between 2015 and 2024. At that rate, severe weather is an event here rather than a constant pressure on equipment, so a system that underperforms after installation is far more likely to be undersized or poorly commissioned than worn down by what the weather has thrown at it. Proper duct sealing, refrigerant charge, and airflow matter more in a county like this than weather-proofing for extreme load.
Ductwork sized and routed for an older forced-air system carries assumptions about static pressure and airflow that a heat pump's distribution demands can expose. Half the homes in Craig County, Virginia were built in 1981 or earlier (2020-2024 ACS 5-year). A contractor installing a heat pump here checks whether the existing duct network moves air at the volume the new equipment requires, and in houses of this vintage that check regularly produces a scope change before the unit itself is even priced. The electrical service gets the same scrutiny, since the draw a modern heat pump places on a panel differs from what the house was wired to handle.
What a Heat Pump Installation Puts in Your Home
The outdoor unit sits on a concrete pad or wall bracket 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.
A refrigerant line set runs between the outdoor unit and the air handler, carrying the working fluid through insulated copper tubing along an exterior wall or through a chase. A thermostat, mounted on an interior wall, gives the homeowner control over the whole system and communicates with both units.
The drawing shows a representative layout, and a licensed contractor determines exactly what applies to your house and how each piece gets positioned.

Severe Weather Events in Craig County, Virginia
Weather in Craig County puts a real load on heating and cooling equipment, and that load shapes which heat pump specs hold up over time. Sizing and installing for local conditions is not a general calculation.
