A heat pump that stops working in Washington County has almost certainly logged years of steady use, and what a contractor finds inside tells that story plainly. 73 severe weather events were recorded in Washington County, Virginia between 2015 and 2024. At that rate, severe weather is a real part of operating life here, not a rare event, but it lands often enough to stress components without being frequent enough to explain most failures on its own. Refrigerant loss, worn contactor points, or a compressor that has simply reached the end of its service life are what a contractor is usually looking for, and the weather history shapes which of those sits at the top of the list.

Houses adapted for heat pump systems long after they were built carry those systems the way the adaptation allowed, which is a settled fact by the time a repair call comes in. Half the homes in Washington County, Virginia were built in 1983 or earlier (2020-2024 ACS 5-year). What that history changes for repair work is where a contractor looks once the unit is open: the compressor, the reversing valve, the refrigerant circuit, and whether the parts a system of that vintage still takes are in supply. The house has already made its accommodation. What the opened equipment actually contains is where the job either stays straightforward or gets complicated.
The Parts of a Heat Pump a Contractor Checks First

The outdoor unit is the piece most homeowners recognize, sitting on a pad beside the house. It holds the compressor and the condenser coil. When the system stops heating or cooling, the compressor is one of the first things a contractor tests, because a failing compressor affects the whole system. The coil inside this unit can also collect damage or debris that forces the compressor to work harder.
Inside the house, the air handler or indoor coil moves conditioned air into the living space. The refrigerant lines run between the two units, and the reversing valve inside the outdoor unit controls which direction the system works. A contractor will check the refrigerant charge, inspect the reversing valve for faults, and look at the air handler's blower and coil for signs of the problem.
