A contractor quoting a heat pump repair in Catahoula Parish starts with the heating side, not the cooling side. Homes in Catahoula Parish, LA run heat about five months a year, from November through March. That load falls on the reversing valve, the defrost board, and the refrigerant circuit that moves heat inward when outdoor air is cold. Those are the components a technician checks first, because they carry the bulk of the annual cycling. Cold-weather demand also pushes a heat pump toward its capacity limit, so a unit that is slightly undersized shows stress in its electrical draws and coil temperatures before it fails outright.
Ductwork in a house this old carries the record of every system that has run through it: flex connections that have stiffened, joints that have shifted, and sections that were patched rather than replaced when the last unit went in. Half the homes in Catahoula Parish, Louisiana were built in 1980 or earlier (2020-2024 ACS 5-year). That puts a contractor diagnosing a heat pump fault in the position of opening equipment that may be fine while the delivery system behind the walls is where the performance is actually going. A refrigerant charge or a failed board is a straightforward repair. Duct losses that have been present since the previous unit was installed change what gets fixed and what gets quoted alongside it.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is the piece most homeowners recognize, a metal cabinet that sits on a concrete pad beside the house, and it holds the compressor and one of the coils. The compressor is the part contractors go to early when a heat pump stops moving heat properly, because it is doing the hardest work. The outdoor coil sits just inside that cabinet and is often where refrigerant problems first show up.
The air handler lives inside the house, usually in a closet, attic, or utility room, and it holds the indoor coil along with the blower that pushes conditioned air through the home. The reversing valve, which sits inside the outdoor unit, is what lets the system run in both directions, and a contractor will test it when the system heats in one season but not the other. The expansion valve and refrigerant lines connect both units and are checked when pressures read off.
The drawing shows a typical heat pump layout, and a licensed contractor determines which parts apply to your specific setup.

Severe Weather Events in Catahoula Parish
Extreme weather puts heat pumps under load they were not built to sustain indefinitely. How often that pressure hits in this area shapes how hard the equipment works and how soon repair needs show up.
