A contractor quoting a heat pump installation in Amherst County has to size the system around what this area actually demands, not around what a catalog suggests for a generic Virginia address. 159 severe weather events were recorded in Amherst County, Virginia between 2015 and 2024. At that rate, severe weather is part of normal operating life here, not an occasional interruption to it, and a system undersized for those conditions will run harder and recover more slowly through exactly the seasons it needs to perform. A contractor who accounts for that load upfront saves the homeowner from a unit that is always catching up.
Ductwork laid in for a furnace or a window unit was sized and routed for a different kind of system, and a heat pump places different demands on it. Half the homes in Amherst County, Virginia were built in 1978 or earlier (2020-2024 ACS 5-year). A contractor sizing a heat pump here checks whether existing ducts can carry the airflow the new unit requires, because if they cannot, the duct work becomes part of the job before the equipment ever gets mounted. The electrical service in houses of that era is the other variable, since heat pumps draw differently than what those panels were originally wired to serve.
What a Heat Pump Installation Puts in Your Home
The outdoor unit sits on a pad beside the house and holds the compressor and the coil that exchange heat with the outside air. Inside, the air handler mounts in a utility space, attic, or closet and moves conditioned air through the home. These two units are the core of what a contractor installs.
A refrigerant line set runs between the outdoor unit and the air handler, carrying refrigerant through insulated copper tubing along the exterior wall. A thermostat goes on an interior wall where it can read the living space accurately and give the homeowner control over the system.
The drawing shows a typical layout, and a licensed contractor determines exactly which components and configurations apply to your house.
