A contractor quoting heat pump repair in Giles County is not working in a weather-battered market. 71 severe weather events were recorded in Giles County, Tennessee between 2015 and 2024. At roughly that rate, severe weather is an event in this county, not a background condition every system fights through. What that means for a failed heat pump is that the compressor, reversing valve, or capacitor that gave out almost certainly did so because of age or deferred service, and a good diagnosis starts there. The contractor will want to know the unit's service history before settling on a repair scope.
A house built for one generation of heating and cooling carries evidence of every system that has run in it since. Half the homes in Giles County, Tennessee were built in 1982 or earlier (2020-2024 ACS 5-year). That history shows up inside the unit itself: compressor wear patterns, refrigerant that has been topped off rather than traced, contactor surfaces that have seen more cycles than the nameplate suggests. A contractor opening a heat pump in stock like this reads those internals closely, because the repair scope follows from what is actually there rather than from what the installation paperwork says.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a pad beside the house and holds the compressor and one set of coils. The compressor is the part contractors go to early when a system stops moving heat properly. The coils beside it are another frequent starting point, since dirt or damage there shows up fast in how the system performs.
Inside the house, the air handler contains a second set of coils and the blower that pushes conditioned air through the home. A reversing valve, which is what lets a heat pump shift between heating and cooling, sits in the refrigerant line and is something a contractor tests when the system runs but delivers the wrong temperature. The refrigerant line itself connects both units and carries the working fluid between them.
The drawing shows a typical layout, and a licensed contractor determines which components and conditions apply to your specific house.
