A heat pump running a full heating season in Panola County puts its compressor, reversing valve, and defrost controls through repeated thermal cycling every winter. Homes in Panola County, MS run heat about five months a year, from November through March. Cold outdoor air forces the system to work harder to extract heat, which loads the compressor more heavily than mild temperatures would. A contractor diagnosing a fault here looks at compressor draw and reversing valve function early, because those are the parts that accumulate the most stress across a season like this one. Refrigerant charge also drifts under sustained heating load, and a low charge that passed unnoticed in fall can be the direct cause of the failure showing up in February.
Ductwork fitted for equipment that has since been replaced once or twice carries the wear of those gaps: seals that no longer close, sections sized for a different load, joints that have pulled loose over successive service cycles. Half the homes in Panola County, Mississippi were built in 1988 or earlier (2020-2024 ACS 5-year). A contractor opening a heat pump here has to treat what the duct system turns out to be as an open question, because what it was built for and what it is running now are not the same thing. If the ducts are losing conditioned air, a part swap on the heat pump unit corrects the equipment and leaves the actual loss in place.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a pad beside the house and holds the compressor, the condenser coil, and a fan. The compressor is the piece contractors look at early: when a heat pump stops moving heat the way it should, that is usually where the fault is. The condenser coil and fan draw heat out of or into the air depending on the season, and a damaged coil or a seized fan motor shows up fast in performance.
Inside the house, the air handler hangs in a closet, attic, or utility space and holds the indoor coil and a blower. The blower pushes conditioned air through the home, and the indoor coil is where the refrigerant does its work on that air. Connecting the two units is the refrigerant line set, which runs through the wall; a leak anywhere along it is a common reason a system loses capacity and gets flagged during a repair call.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines exactly which components apply to your house and what each one needs.
