A contractor quoting a heat pump repair in Greene County has to settle one question early: is the failure weather-related or is it wear? 39 severe weather events were recorded in Greene County, Alabama between 2015 and 2024. At that rate, severe weather is an occasional event in a system's life, not a standing condition, so a refrigerant leak or a failing capacitor is more likely a product of age and how well the unit was installed than of storm load. A contractor who skips that distinction and prices around weather exposure is solving the wrong problem.

Half the homes in Greene County, Alabama were built in 1981 or earlier (2020-2024 ACS 5-year). A heat pump installed into housing of that vintage has been running against wiring and refrigerant lines that predate it, and the wear those components carry shows up once the unit is open. What a contractor finds inside a system here tends to be a record of that accumulated stress: corroded contacts, stressed capacitors, refrigerant circuits that have cycled through more seasons than their tolerances were sized for. The age of the house is not academic detail; it is what pushed those parts to where they are.
The Parts of a Heat Pump a Contractor Checks During Repair

The outdoor unit is usually where a contractor starts. It holds the compressor, which moves refrigerant through the system, and the condenser coil, which releases or absorbs heat at the outside air. When either of those fails, the whole system feels it. The outdoor fan pulls air across the coil, and a seized or slow fan shows up fast in performance.
Inside the house, the air handler contains the evaporator coil and the blower that pushes conditioned air into the living space. The reversing valve sits within the refrigerant circuit and is what lets a heat pump heat as well as cool. The expansion valve and refrigerant lines run between the two units, and a problem anywhere along that path can point blame at the wrong component if a contractor does not trace it carefully.
The drawing shows a general layout of these components, and a licensed contractor determines what applies to your specific house and system.
