A heat pump working a Jasper County winter runs its refrigerant circuit hard. Capacity drops as outdoor temperatures fall, which means the compressor cycles more frequently to hold setpoint and the reversing valve shifts under load. Homes in Jasper County, SC run heat about five months a year, from November through March. A contractor diagnosing a failed heating cycle here checks the reversing valve and refrigerant charge before anything else, because those are the components the heating season actually punishes. Defrost cycles add to that load each time the outdoor coil ices over. Backup heat strips get switched on more than a homeowner usually realizes, and a failed strip can go unnoticed until outdoor temperatures drop again.
Half the homes in Jasper County, South Carolina were built in 2003 or earlier (2020-2024 ACS 5-year). A heat pump running in a house from that era has often been swapped in after the original equipment was retired, which means what a contractor finds inside the unit carries the marks of those transitions: refrigerant lines rerouted, connections that were made to fit rather than made to spec, and wear patterns that differ from a system installed new into a purpose-built setup. When a repair call comes in, the opened unit is where the job actually gets defined. A failed capacitor in one house is a straightforward swap; the same symptom in a house where prior work left the wiring adapted to fit can change the scope entirely.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a pad beside the house and holds the compressor, which is the part contractors go to first when a heat pump stops doing its job. The compressor moves refrigerant through the system, so when it labors or fails, the whole system feels it. The coil wrapped around it and the fan above it are close behind on the inspection list.
Inside the house, the air handler hangs in a closet, attic, or utility space and contains a second coil along with the blower that pushes conditioned air into the living space. The refrigerant line set runs between the two units, and the reversing valve inside the system is what lets a heat pump both heat and cool. A contractor checks all of these when tracing a fault.
The drawing shows a typical layout, and a licensed contractor will determine which components apply to your specific house and system.
