A contractor coming out to repair a heat pump in Winchester has to work through what the system has already been carrying before they can name a cause. 32 severe weather events were recorded in Winchester city, Virginia between 2015 and 2024. At that rate, severe weather is a routine condition for equipment here, and the reversing valve and refrigerant circuit absorb that load in ways that show up later as apparent failures of unrelated parts. A repair quote that skips that check can misidentify the problem and replace the wrong component.
Ductwork routed and sealed for a different era of equipment develops leaks and restrictions that load a heat pump in ways the unit was never built to handle, and those stresses show up later as component failures. Half the homes in Winchester city, Virginia were built in 1968 or earlier (2020-2024 ACS 5-year). A contractor pulling a heat pump apart here checks the refrigerant circuit and the electrical connections, but also traces what the duct system has been doing to system pressure and airflow over years of use. A fault that looks like a bad reversing valve or a failing capacitor sometimes turns out to be a duct restriction that has been running the compressor hard. The repair the homeowner pays for is decided by which of those it actually is.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and the outdoor coil. The compressor is where most repair calls begin: when it fails, the system moves no heat at all. The outdoor coil works alongside it, and a contractor will inspect both early in any diagnosis.
Inside the house, the air handler pushes conditioned air through the home and contains the indoor coil and the blower motor. The reversing valve, which sits in the refrigerant line and tells the system whether to heat or cool, is another piece a contractor checks when the system runs but delivers the wrong temperature. The refrigerant lines that connect the two units carry the working fluid between them, and a leak anywhere along that path will show up in the contractor's pressure readings.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components apply to your specific house and situation.

Severe Weather Events in Winchester city
Extreme weather puts heat pumps under the kind of sustained load that accelerates wear and surfaces faults that moderate conditions would leave hidden. How hard the equipment works in Winchester is a local question, and the record of weather events here shapes the answer.
