A contractor quoting a heat pump repair in Obion County has to decide what actually wore the system down. 85 severe weather events were recorded in Obion County, Tennessee between 2015 and 2024. At that rate, severe weather is a recurring presence in the life of any equipment here, but it falls short of the relentless load that would make storm stress the default explanation for a failed component. A refrigerant leak or a failing capacitor in this county is just as likely to trace back to age and how well the unit was serviced as to weather-related strain, and a contractor works out which it is before pricing the repair.
A heat pump that has been running in a house built for a different era of equipment is already working through a parts catalog that gets thinner every year. Half the homes in Obion County, Tennessee were built in 1975 or earlier (2020-2024 ACS 5-year). When a contractor opens a unit here, the question is not just what failed but whether a replacement part is still manufactured for that system. If it is not, the repair scope changes before a quote can be written.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and condenser coil. These are where most failures show up. A bad compressor means the system cannot move heat at all. A damaged coil or a refrigerant leak in that circuit will leave the house too warm or too cold no matter how long the system runs.
Inside, the air handler holds the evaporator coil, the blower, and the reversing valve that tells the system which direction to work. The thermostat ties everything together. A contractor checks the capacitors, the contactor, and the refrigerant charge alongside those, because a fault in any of them can mimic a much bigger problem.
The drawing shows a typical layout, and a licensed contractor determines what applies to this specific house and system.
