A contractor called out to repair a heat pump here checks the reversing valve and the refrigerant charge before anything else, because those are the components that determine whether the unit can pull heat from cold outdoor air at all. Homes in Jackson Parish, LA run heat about five months a year, from November through March. A short heating season means the system can run fine through summer cooling and then fail silently in the off-months, so the first cold spell is often the first sign something went wrong. By then the compressor has already been asked to do exactly what it struggled to do last winter, and a repair quote that ignores that history will miss the part that is actually failing.
Ductwork in a house this old has had a long time to collect what sealing failures, humidity, and deteriorating lining produce inside the runs. Half the homes in Jackson Parish, Louisiana were built in 1979 or earlier (2020-2024 ACS 5-year). A contractor opening a heat pump here often finds that the equipment itself is in serviceable shape, but the duct system feeding it is carrying restricted airflow from collapsed flex sections or clogged returns, and those conditions are what drove the call. Parts for heat pumps of this generation are still available, so the repair is often straightforward once the real cause is traced back through the duct runs.
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 outdoor coil. The compressor is where most repair calls begin. It pressurizes refrigerant, and when it falters the whole system loses the ability to move heat. The outdoor coil, which surrounds the compressor, transfers that heat to or from the outside air, and bent fins or refrigerant loss here will show up fast.
Inside the house, the air handler pulls indoor air across the indoor coil and pushes conditioned air into the ducts. A failing blower motor or a frozen coil points a contractor straight to this unit. The refrigerant lines that connect the two units and the reversing valve that switches the system between heating and cooling are also checked early when the symptom does not point clearly to one component.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which parts apply and what they find in your particular home.
