Sizing a heat pump for this area starts with what the climate routinely puts the system through. 121 severe weather events were recorded in Shenandoah County, Virginia between 2015 and 2024. At that rate, severe weather is a standing condition rather than an occasional disruption, which means a contractor quoting an install here has to treat local load as a primary input, not a footnote. A unit sized from a catalog without that adjustment will run harder than it was rated for and lose efficiency before it should.
Ductwork laid down for a gas furnace or a window unit was sized around a different airflow requirement than a heat pump runs on, and in Shenandoah County's housing stock that gap shows up on job after job. Half the homes in Shenandoah County, Virginia were built in 1983 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump here pulls at the existing duct runs first, checking whether the supply and return can move the volume the new system needs. Where they cannot, the duct work becomes a bigger line item than the unit itself.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, mounted on a concrete pad or bracket outside the house, and it holds the compressor and the coil that exchange heat with the outside air. Inside, the air handler sits in a utility closet, basement, or attic and moves conditioned air through the home. Together these two units are the heart of the installation.
A refrigerant line set runs between the outdoor unit and the air handler, carrying refrigerant through insulated copper tubing that a contractor runs along the exterior wall or through a chase. A thermostat goes on an interior wall and gives the homeowner control over the whole system.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece is positioned and connected in your home.

Local weather puts real demands on heating and cooling equipment, and those demands shape what a heat pump in Shenandoah Valley needs to handle year after year. Sizing and installation decisions that ignore local conditions leave equipment working against the climate rather than with it.
