A contractor quoting a heat pump repair here starts with what the system has already been running against. 188 severe weather events were recorded in Prince William County, Virginia between 2015 and 2024. At that rate, every refrigerant line, contactor, and reversing valve in the county has been working through real weather stress, and a failing component is as likely carrying that load as it is wearing out from age alone. The contractor has to open the system and look before drawing a conclusion either way.
Half the homes in Prince William County, Virginia were built in 1995 or earlier (2020-2024 ACS 5-year). Stock built around that time was designed and wired with equipment closer to what runs in it today, which means the building is unlikely to be where a repair gets complicated. When a heat pump fails here, what a contractor finds once the unit is open decides the job: the condition of the compressor, whether the reversing valve is the source, which components have worn and what parts are still available for a system of that model and age. The house tends to stay out of the way.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is usually the first thing a homeowner notices, and it is often where a repair begins. It houses the compressor and the condenser coil, and when either of those fails the whole system stops moving heat. The air handler sits inside, typically in a closet or utility space, and pushes conditioned air through the home.
The reversing valve lives inside the outdoor unit and is what lets a heat pump switch between heating and cooling modes. A contractor also checks the expansion valve, the refrigerant lines running between the two units, and the thermostat, since a fault in any of those can produce symptoms that look like a compressor problem but are not.
The drawing shows a general layout of these components, and a licensed contractor determines what applies to your specific system and house.
