A contractor diagnosing a heat pump repair in Weakley County checks the compressor contacts, the reversing valve, and the capacitor before weighing how much the local weather contributed to the failure. 80 severe weather events were recorded in Weakley County, Tennessee between 2015 and 2024. At that rate, severe weather is a real but occasional presence, not a constant grind on equipment, so a failed component is more likely tracing back to installation quality or deferred maintenance than to storm load. A contractor who can tell the difference quotes a targeted repair rather than a full system replacement.
Ductwork and wiring put in before heat pumps were a standard residential choice has been adapted over the decades, and what a contractor opens on a repair call reflects that layered history. Half the homes in Weakley County, Tennessee were built in 1977 or earlier (2020-2024 ACS 5-year). A system running in a house that old has been subject to previous repairs, workarounds, and parts substitutions that do not appear in any service record the homeowner has. When a contractor opens a heat pump here, the question is whether the failed component is still manufactured to the spec that unit requires, and what a substitute will cost if it is not.
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 one set of coils. The compressor is where most repair calls start. When it struggles or fails, the whole system either runs poorly or stops moving heat entirely. The coils inside that cabinet are the next thing a contractor looks at, since damage or refrigerant loss shows up there.
Inside the house, the air handler holds a second set of coils and the blower that pushes conditioned air through the home. The reversing valve, which lives in the outdoor unit, is what lets the system heat in winter and cool in summer. When it sticks, the system locks into one mode. The expansion valve and refrigerant lines connect both sides and are checked whenever pressures read wrong.
The drawing shows a typical layout, and a licensed contractor determines which components apply to the specific system in your home.

Severe Weather Events in Weakley County
Extreme weather puts heat pumps under load at the worst possible moments, and equipment that runs hard through storms accumulates wear that shows up later as repair calls. How often that pressure arrives is a local fact, which is why a contractor working in Weakley County reads this data before anything else.
