A heat pump runs its compressor and reversing valve hard through every heating cycle, and in this parish the heating demand is concentrated enough that those components carry the load rather than sharing it across mild shoulder months. Homes in Tangipahoa Parish, LA run heat about five months a year, from November through March. Compressor wear from repeated cold-weather starts shows up in refrigerant pressure readings, and a contractor working a repair here checks that first before pricing anything else. A reversing valve that stuck or bled through during the heating season will not advertise itself in summer.
Half the homes in Tangipahoa Parish, Louisiana were built in 1993 or earlier (2020-2024 ACS 5-year). A heat pump that has worked through that many years of south Louisiana summers accumulates damage in specific places: contacts corrode, capacitors weaken, and refrigerant lines develop small leaks at fittings that have expanded and contracted through hundreds of cooling seasons. A contractor opening a unit in this parish should expect to find the real repair scope inside the equipment, not on the nameplate.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and the outdoor coil. These are the parts a contractor goes to early in a repair call. When the compressor fails, the system runs but moves no heat. When the coil is damaged or heavily fouled, the same symptom shows up for a different reason.
The air handler sits inside, usually in a utility closet or attic, and pushes conditioned air through the house. It contains the indoor coil and the blower motor, both of which are common fault points. The reversing valve, which sits in the outdoor unit, is what a contractor checks when the system heats in cooling mode or cools in heating mode. The expansion valve and the refrigerant lines connect the two units and are part of the circuit a contractor pressure-tests when refrigerant loss is suspected.
The drawing shows the general layout of the system, and a licensed contractor determines which components apply and what condition they are in for your specific home.

Severe Weather Events in Tangipahoa Parish
Storm activity puts heat pumps through cycles of stress they were not necessarily sized to absorb alone. How hard a unit works, and how often it needs repair, is shaped by the weather it runs against, and that weather is a local variable.
