A contractor diagnosing a heat pump repair in Alleghany County has to separate what the weather has contributed from what the system itself was always going to do. 62 severe weather events were recorded in Alleghany County, Virginia between 2015 and 2024. At that rate, severe weather is an event in this county, not a condition every system has been grinding against. A compressor that fails here is far more likely to have reached the end of its mechanical life or to be showing the effects of a marginal install than to have been pushed past its limit by storm load. Refrigerant lines, contactor condition, and run-capacitor wear are what a contractor checks first, because those are what age and cycling kill.
Ductwork in a house this age has carried more than one system in its life, and the heat pump running in it today is likely not the first. Half the homes in Alleghany County, Virginia were built in 1969 or earlier (2020-2024 ACS 5-year). When a contractor opens the unit, what matters is the specific components inside and whether manufacturers still supply them. An older refrigerant circuit or a control board from a production run that closed years back can turn a straightforward repair into a parts search, and that search is what sets the real scope of the job.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and the condenser coil. The compressor is where most repair calls start. When it fails, the system runs but moves no heat; when the condenser coil is damaged or blocked, the outdoor unit strains and the rest of the system follows.
Inside, the air handler holds the evaporator coil and the blower fan, and it sits in a utility space, closet, or attic depending on the house. The refrigerant lines run between the two units and the expansion valve controls flow between them. A fault in the refrigerant circuit, the blower motor, or the valve shows up in how the system behaves at the thermostat.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which parts apply and what needs attention in your specific home.

Severe Weather Events in Alleghany County
Heat pumps work hardest when the weather swings hard, and each storm cycle puts mechanical stress on components that were already running at capacity. How often that happens in Alleghany County shapes what local repair work looks like and how quickly parts wear.
