A heat pump repair in Hardeman County starts with the system itself, not with the weather outside. 62 severe weather events were recorded in Hardeman County, Tennessee between 2015 and 2024. At that rate, severe weather is an event here, not a standing condition, so a compressor that has lost capacity or a reversing valve that has failed is almost certainly carrying the weight of years of run hours and service gaps rather than storm load. A contractor working through a diagnosis will price out the refrigerant charge, inspect the coil, and pull the service history before the weather becomes a factor at all.
Ductwork and wiring in houses this old have already been adapted once, maybe more than once, but the harder question in a heat pump repair is what the opened system actually requires. Half the homes in Hardeman County, Tennessee were built in 1982 or earlier (2020-2024 ACS 5-year). A compressor or reversing valve pulled from a unit that age may take a part that is no longer in regular production, which changes what a contractor can order, how long a repair takes to finish, and whether a repair is the sensible path at all. The age of the housing is background; what the opened equipment needs is what drives the job.
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 first. A contractor will check the compressor for signs it is drawing too much current or not building pressure, and inspect the coil for damage, fouling, or refrigerant leaks that starve the whole system.
Inside, the air handler houses the evaporator coil and the blower that moves conditioned air through the house. The expansion valve and the reversing valve sit within the refrigerant circuit and control how the system shifts between heating and cooling. A fault in either one shows up as the system running but not performing.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components and connections apply to your particular house.
