A heat pump struggling in Jackson County is more likely failing from age or deferred maintenance than from storm wear. 58 severe weather events were recorded in Jackson County, Tennessee between 2015 and 2024. That rate puts severe weather in the category of an occasional event rather than a standing operating condition, which shapes what a contractor checks first: capacitors, refrigerant levels, and compressor wear that accumulate regardless of what the sky has been doing. A homeowner pressing for answers about a failed component should expect the contractor to price the repair around those factors, not around the weather record.
Half the homes in Jackson County, Tennessee were built in 1989 or earlier (2020-2024 ACS 5-year). A heat pump dropped into a house built that long ago was added to infrastructure that predates it, and the refrigerant circuits, control boards, and compressor components it takes may sit outside what suppliers still stock as standard. When a contractor opens the unit, the age printed on the nameplate drives the parts search more than anything else about the job. Some components come back in stock quickly; others have to be sourced, and a few are no longer made at all.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and the outdoor coil. The compressor is where most repair calls start: when it fails, the system moves no heat at all. The outdoor coil works alongside it, and a damaged or dirty coil will make the compressor strain before it eventually quits.
Inside the house, the air handler pushes conditioned air through the home and contains the indoor coil and the blower motor. A faulty blower motor means weak or no airflow even when the outdoor unit is running fine. The reversing valve, also inside the refrigerant circuit, is what lets the system heat in winter and cool in summer, and a stuck valve is a repair a contractor will test for early.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components apply to the specific setup in your house.
