A heat pump running a repair call in Lafourche Parish carries a specific maintenance profile. Homes in Lafourche Parish, LA run heat about four months a year, from November through February. The compressor and reversing valve take their heating-mode stress in a concentrated stretch, then sit largely idle. Faults that develop during heating cycles often go unnoticed until the system starts up again under load, which is when a contractor finds accumulated wear rather than a fresh failure. Refrigerant loss, valve drift, and coil degradation all look older than the last complaint on the service record.
Ductwork installed for an earlier generation of equipment does not always carry what a heat pump now asks of it, and a repair call can widen once a contractor gets into the system. Half the homes in Lafourche Parish, Louisiana were built in 1982 or earlier (2020-2024 ACS 5-year). That means a technician diagnosing a refrigerant or coil problem here checks the line set condition and duct connections alongside the unit itself, because a failure traced to the heat pump can have its actual cause further back in the run.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is the piece most homeowners recognize, a metal cabinet sitting on a pad beside the house that holds the compressor and the outdoor coil. The compressor is where a contractor starts when a heat pump stops moving heat properly, because it does the pressurizing work the whole system depends on. The outdoor coil sits around it and is a common source of problems when it is bent, blocked, or iced over.
Inside the house, the air handler holds the indoor coil and the blower fan, and it is the piece a contractor checks when airflow is weak or when the system runs but the air coming out feels wrong. The reversing valve, which sits inside the outdoor unit, is what a contractor looks at when a heat pump heats in one season but fails to cool in the other, or vice versa. The expansion valve and refrigerant lines connect both units and are checked when pressures read off or refrigerant has leaked.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which parts apply and what work is needed in your specific home.
