A contractor quoting a heat pump installation in Orange County has to account for what the system will actually run against here. 173 severe weather events were recorded in Orange County, Virginia between 2015 and 2024. At that rate, severe weather is a standing feature of local operating conditions, and a unit sized or fitted for gentler demands will be working outside its design range from the start. Refrigerant line quality, weatherproofing at every penetration, and electrical connections all carry more consequence here than they do in quieter parts of the country.
Ductwork laid down for a furnace or central air unit carries assumptions about airflow that a heat pump does not share, and in Orange County a large share of the housing stock was built when those older systems were the default. Half the homes in Orange County, Virginia were built in 1993 or earlier (2020-2024 ACS 5-year). A contractor sizing and placing new equipment here will spend real time on what the existing ducts can move, where they run, and whether the supply and return layout suits how a heat pump actually delivers conditioned air. The electrical service gets the same look: the circuit a new unit needs drawn to it is not always what was roughed in. What the house already contains is where the installation quote gets shaped.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, mounted on a concrete pad beside the house. Inside, an air handler sits in a utility closet, basement, or attic and moves conditioned air through the home. These two units are the heart of what a contractor puts in.
A refrigerant line set runs between the outdoor unit and the air handler, carrying the working fluid through both. A thermostat goes on an interior wall where it reads the living space and tells the system when to run. Electrical disconnect boxes and control wiring tie all of it together.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines exactly what applies to this house.

Severe Weather Events in Orange County
Heating and cooling loads are driven by what the climate actually does to a home, and that includes the stress of severe weather. A heat pump sized and installed for local conditions handles that workload better than one specified for somewhere else.
