A contractor quoting a heat pump repair in Cheatham County starts with the system itself: how old the equipment is, how it has been serviced, and which components show wear independent of what the sky has thrown at it. 85 severe weather events were recorded in Cheatham County, Tennessee between 2015 and 2024. At that rate, severe weather is a real part of operating here, but it sits in a range where age and installation quality are stronger predictors of what fails. Refrigerant loss, compressor wear, and control board faults in this area trace back to deferred maintenance as often as they do to storm load, and a contractor prices the repair around what the opened unit actually shows.
Heat pumps running in houses built before the early nineties have typically seen multiple Tennessee summers and winters by now, and what matters when one fails is what a contractor finds once the cabinet is open: the actual state of the coils, the contacts, and the refrigerant circuit. Half the homes in Cheatham County, Tennessee were built in 1992 or earlier (2020-2024 ACS 5-year). A house that old tells you a repair call is plausible; it does not tell you which component gave out or whether a replacement part is still in production for that specific model. The opened unit does.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is the piece most homeowners recognize on sight. It holds the compressor, which is the heart of the system, and the outdoor coil. When a heat pump stops heating or cooling, the compressor and that coil are where a contractor starts, because faults there show up fast in how the whole system behaves.
Inside the house, the air handler pushes conditioned air through the home and contains the indoor coil and the blower motor. The reversing valve, which is what allows a heat pump to shift between heating and cooling, sits in the outdoor unit and is a common target when the system runs but delivers the wrong temperature. The expansion valve and refrigerant lines connect the two units and carry the working fluid between them.
The drawing shows a general layout of these components, and a licensed contractor determines exactly which parts apply to your specific system and situation.

Severe Weather Events in Cheatham County
Extreme weather puts real stress on heat pump systems, pushing them to run harder and longer than normal conditions demand. How much of that stress a unit absorbs over its life is a local question, shaped by what actually happens in this county.
