Homes in Orleans Parish, LA run heat about five months a year, from November through March. The reversing valve cycles every time the system switches between heating and cooling modes, and a heating season this long puts that valve through enough cycles that wear shows up in the valve itself rather than in surrounding components. The refrigerant circuit carries the same story: coil surfaces and the compressor bearings accumulate load from sustained cold-weather operation. A contractor quoting a repair in Orleans Parish checks both before pricing anything else.
A heat pump running in a house this old is almost certainly not the system the house was built for. Half the homes in Orleans Parish, Louisiana were built in 1960 or earlier (2020-2024 ACS 5-year). That gap matters for repair work because the refrigerants, control boards, and compressor components a contractor finds once the unit is open may come from a parts ecosystem that has contracted or closed. If a part is still made, a contractor sources it. If it is not, the scope of the repair changes before anything else does.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is usually where a contractor starts. It holds the compressor, the condenser coil, and the fan that pulls air across them. When the system stops moving heat the way it should, a failed compressor, a refrigerant leak at the coil, or a seized fan motor are the first things to rule out.
Inside the house, the air handler contains the evaporator coil and the blower that pushes conditioned air into the living space. The reversing valve, which sits in the refrigerant line and tells the system which direction to run, is a common fault point when a heat pump heats in one season but fails in the other. The expansion device that meters refrigerant between the two coils is checked alongside it.
The drawing shows a typical heat pump layout, and a licensed contractor determines which components apply and what condition they are in for your specific home.
