A contractor quoting a heat pump repair in Montgomery County has to sort out what the equipment has actually been running against. 128 severe weather events were recorded in Montgomery County, Virginia between 2015 and 2024. Severe weather at that rate puts a real and recurring load on a heat pump's compressor and reversing valve, and a contractor working a repair here checks both for stress-related wear before pricing anything else. A unit that looks old on paper may have a failed reversing valve that wore under weather load, and a unit that looks weather-beaten may have a compressor that simply aged.
A heat pump sitting in a house built around the median year for this county has likely outlasted at least one round of parts availability. Half the homes in Montgomery County, Virginia were built in 1986 or earlier (2020-2024 ACS 5-year). When a contractor opens a system in stock that old, the question that shapes the repair is whether the compressor, reversing valve, or control board it takes is still in regular production. If the part has gone to specialty-only supply, the job cost shifts well before anyone touches labor. That is what the opened unit settles, and why the parts search runs alongside the diagnosis rather than after it.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is usually where a repair call starts. It houses the compressor, which is the engine of the whole system, and the condenser coil wrapped around it. When the system short-cycles, makes noise, or stops moving heat altogether, the compressor and coil are the first places a contractor looks.
Inside the house, the air handler holds the evaporator coil and the blower fan. The coil pulls heat out of the indoor air; a frozen coil or a refrigerant leak shows up here. The expansion valve, which sits between the two coils, controls refrigerant flow and is a common source of pressure problems.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines what applies to your specific house and equipment.

Weather Stress on HVAC Equipment in Montgomery County, Virginia
Extreme weather puts heat pumps under load they were not built to sustain indefinitely. How hard a system works, and how often it strains, shapes what breaks and when a repair call becomes necessary.
