A contractor quoting a heat pump installation in Falls Church has to account for what the equipment will actually run against, and the weather record here is part of that picture. 26 severe weather events were recorded in Falls Church city, Virginia between 2015 and 2024. At that rate, severe weather is a real but occasional factor rather than a constant operating condition, which means sizing decisions turn on the home's heating and cooling load, construction details, and duct layout more than on storm exposure. A system specified correctly for this house will carry the climate without being over-built around it.
Ductwork laid down for older heating systems carries assumptions about airflow that a heat pump does not share, and in Falls Church city's housing stock those assumptions are built into the bones of the house. Half the homes in Falls Church city, Virginia were built in 1971 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump installation here looks at the existing duct layout and the electrical service before the equipment selection means much. If the ducts restrict airflow or the panel cannot carry the new load, those are the jobs that shape the final scope.
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, an air handler mounts in a utility space, closet, or attic and moves conditioned air through the home. These two units are what a contractor brings to the job.
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. Some installations also include a supplemental electric resistance element inside the air handler to cover the coldest days.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house and how each piece positions within it.
