The reversing valve on a heat pump sees real use here, switching the system into heating mode and holding it there through a genuine winter. Homes in Nevada County, AR run heat about five months a year, from November through March. Capacity drops as outdoor temperatures fall, so the refrigerant circuit works harder on the coldest nights than it does in shoulder weather, and that repeated strain is where a contractor starts when diagnosing a fault. Coil condition and refrigerant charge both shift under sustained heating load, and neither shows up clearly until someone measures them.
Heat pumps running in houses like these have usually outlasted the infrastructure they were retrofitted into, which means a repair call opens questions the exterior of the house cannot answer. Half the homes in Nevada County, Arkansas were built in 1983 or earlier (2020-2024 ACS 5-year). A contractor pulling the access panel on a system this county's housing stock typically carries is checking whether corroded electrical connections, worn capacitors, or degraded refrigerant lines are what drove the failure. Those are the findings that decide the scope. Parts availability for equipment of that vintage is its own question, and the answer shapes whether a repair is the right path or whether the homeowner is pricing one anyway.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits at ground level 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 fouled or damaged, the same symptom follows.
The air handler lives inside, usually in a closet, attic, or utility room, and pulls house air across the evaporator coil before pushing it back through the vents. The reversing valve, which sits inside the outdoor cabinet, is the part that lets a heat pump heat in winter and cool in summer. A stuck or leaking reversing valve is a common reason a system blows warm air in cooling mode or cold air in heating mode.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines what applies to your specific house.
