A heat pump running through years of genuine weather pressure accumulates wear in specific places. 74 severe weather events were recorded in Washington County, Alabama between 2015 and 2024. At that rate, a contractor diagnosing a repair here checks the outdoor coil for physical stress, tests the capacitor, and inspects refrigerant line connections before settling on any other explanation. Those are the components that carry the load when severe weather is a standing feature of where the system sits, and skipping them means misreading what actually drove the failure.
Ductwork sized for a different system and retrofitted electrical can put quiet stress on a heat pump from the day it starts running. Half the homes in Washington County, Alabama were built in 1984 or earlier (2020-2024 ACS 5-year). A unit that has been working against those conditions may show refrigerant pressure irregularities, compressor strain, or cycling behavior that looks like component failure but traces back to what the system was asked to do from the start. When a contractor opens the unit, those patterns are what determine whether the repair is a part swap or the beginning of a longer conversation about what the system has been running against.
The Parts of a Heat Pump a Contractor Checks During Repair
The outdoor unit is usually what draws attention first. It sits on a pad beside the house and holds the compressor and the outdoor coil. The compressor is the heart of the system, and when a heat pump stops moving heat in either direction, the contractor starts there. The outdoor coil works alongside it, and a damaged or fouled coil will show up in how the whole system behaves.
Inside the house, the air handler contains the indoor coil and the blower that pushes conditioned air through your home. The reversing valve, which is what lets a heat pump heat and cool, sits in the refrigerant circuit and is a common focus during repair. The expansion valve and the refrigerant lines connecting both units round out what a contractor works through when tracing a fault.
The drawing beside this text shows the general layout of a heat pump system, and a licensed contractor determines which components and conditions apply to your specific home.

Severe Weather Events in Washington County
Weather puts real load on heat pump equipment, and load is what drives repair needs. How hard a system works over the years is a local question, and the record of weather events here is part of that answer.
