A heat pump in Polk County has not been running against a relentless severe weather load. 71 severe weather events were recorded in Polk County, North Carolina between 2015 and 2024. At that rate, the compressor that quit last August or the reversing valve that started hunting in winter is almost certainly carrying the marks of age and deferred service, not accumulated storm damage. A contractor here will check refrigerant charge, capacitor health and coil condition before entertaining any other explanation, because those are what fail on a system that has simply run a long time without much attention.
Refrigerant lines corrode, electrical contacts oxidize, and contactor points pit in ways that accumulate quietly over years of cycling. Half the homes in Polk County, North Carolina were built in 1984 or earlier (2020-2024 ACS 5-year). A heat pump sitting in a house built that long ago has likely run through multiple owners and possibly multiple repair attempts, and what a contractor finds once the system is open reflects that history: stress on the compressor terminals, brittle insulation on low-voltage wiring, capacitors that test marginal rather than failed. Parts availability is a real variable at this service age and shapes what a repair costs and how long it takes to complete.
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 often the first piece a contractor looks at, because when it fails, the whole system stops moving heat. The condenser coil sits around it and is where heat passes into or out of the outdoor air.
Inside the house, the air handler contains the evaporator coil and the blower fan, which push conditioned air into the living space. The reversing valve, housed in the outdoor unit, is what lets the system run in both heating and cooling modes, and it is a common point of failure when the system runs but stops switching between them. The expansion valve meters refrigerant flow and sits between the two coils.
The drawing shows the general layout of these components, and a licensed contractor determines what applies to your specific system and installation.
