A heat pump installation in Rockbridge County has to be sized for what the climate actually delivers, not for what a catalog recommends in the abstract. 153 severe weather events were recorded in Rockbridge County, Virginia between 2015 and 2024. At that rate, severe weather is part of normal operating life here, and a contractor who ignores it when selecting equipment and planning the install is setting the system up to run harder than it was designed to. Refrigerant line placement, unit mounting, and equipment ratings all get decided with that load in mind.
Ductwork laid down for a furnace or a window unit was sized and routed for a different kind of system. Half the homes in Rockbridge County, Virginia were built in 1980 or earlier (2020-2024 ACS 5-year). A heat pump moves air differently, and what a contractor finds behind the walls of a house this old shapes the whole job: whether existing ducts can carry the new system's airflow, and whether the electrical service will handle the load. Those two questions get answered before anything else is priced or ordered.
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 exchanges heat with outside air. 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 gets installed.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two through an exterior wall. A thermostat goes on an interior wall where it reads the living space and signals the system to run or stop. A condensate drain line also runs from the air handler to carry away moisture the coil pulls from indoor air.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits your house.
