A contractor quoting a heat pump repair here starts from age, installation quality, and maintenance history, because those are what drive failures in a county where severe weather stays an event rather than a condition. 40 severe weather events were recorded in Hancock County, Tennessee between 2015 and 2024. At that rate, most systems in the county have spent the bulk of their operating life in ordinary weather, which means a failed reversing valve or a dead compressor points toward wear and neglect long before it points toward storm load. The contractor checks refrigerant levels, electrical connections, and the age of the unit.
Heat pumps running in houses built this long ago have usually been through at least one equipment swap, and the systems in them today are not always drawing from a deep parts supply. Half the homes in Hancock County, Tennessee were built in 1982 or earlier (2020-2024 ACS 5-year). When a contractor opens a unit here, what decides the repair is often not the diagnosis itself but whether the specific compressor, reversing valve, or control board that system takes can still be sourced. If a part is discontinued, the scope of the job changes in ways that have nothing to do with how the failure happened.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and the condenser coil. The compressor is where most repairs begin. When it fails, the system runs but moves no heat. The condenser coil wraps around it, and a damaged or fouled coil can show the same symptoms as a compressor going bad.
Inside the house, the air handler holds the evaporator coil and the blower motor. The evaporator coil is a common site for refrigerant leaks, which a contractor traces by pressure and by residue. The blower motor and its capacitor are checked separately, since a weak capacitor can mimic a failing motor. The reversing valve, which sits in the outdoor unit, is the piece a contractor looks at when the system heats in one mode but not the other.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines what applies to the specific equipment and configuration in your house.

Severe Weather Events in Hancock County, Year by Year
Extreme weather puts heat pumps under sustained stress, and the repair demands that follow are shaped by local conditions. That makes weather history in this area a real factor in how hard the equipment works and how often it needs attention.
