A contractor diagnosing a heat pump repair in Vermilion Parish starts with the reversing valve and the defrost board, because the heating cycle is where this equipment earns its wear. Homes in Vermilion Parish, LA run heat about five months a year, from November through March. Through those months the reversing valve switches the refrigerant loop on every cycle, and the defrost controls fire whenever the outdoor coil ices. Both parts carry the bulk of what accumulates over a heating season, and when a heat pump comes in short on capacity or cycling oddly, that is where the fault most often sits.
Ductwork and wiring in a house this age have usually outlived the original equipment by a wide margin, which means a contractor opening a heat pump here is working on a system whose maintenance record rarely matches the house's own age. Half the homes in Vermilion Parish, Louisiana were built in 1983 or earlier (2020-2024 ACS 5-year). That gap between structure and equipment shows up most clearly inside the unit: capacitors, contactors, and refrigerant circuits that have cycled through Louisiana summers without consistent records are harder to assess from the outside than from within. What the opened system contains sets the repair scope, and parts availability for whatever generation of heat pump is actually running decides whether that scope is straightforward or not.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a pad beside the house and holds the compressor and the condenser coil. The compressor is where most repair calls begin: when it struggles or stops, the whole system stops moving heat. The condenser coil wraps around it and sheds or absorbs heat depending on the season, so a damaged or dirty coil shows up fast.
Inside the house, the air handler contains the evaporator coil and the blower fan, usually in a closet, attic, or utility room. The expansion valve sits between the two coils and controls refrigerant flow. Refrigerant lines connect the indoor and outdoor units, and the reversing valve inside the outdoor cabinet is what lets the system run in both heating and cooling modes.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific system and home.
