A heat pump that stops working in Robertson County probably did not get worn down by weather. 16 severe weather events were recorded in Robertson County, Kentucky between 2015 and 2024. At that rate, severe weather is an event here, not a standing condition, so a contractor opening a failed compressor or reversing valve is looking at age and installation quality before anything else. A system that was undersized at the start or has gone years without a filter change does not need a dramatic explanation for why it failed.
Ductwork and wiring in houses built for an earlier generation of equipment may have been adapted over the years, but when a heat pump needs repair, the housing is rarely where the answer lives. Half the homes in Robertson County, Kentucky were built in 1985 or earlier (2020-2024 ACS 5-year). A system installed into stock that age has been running long enough to accumulate its own record: capacitors, reversing valves, refrigerant circuits, and contactor points that reflect years of heating and cooling cycles, not the decade on the building permit. What a contractor opens tells them whether those parts are still serviceable and whether the manufacturer still makes what the system takes.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a pad outside the house and holds the compressor, the outdoor coil, and the fan that moves air across it. These are the pieces a contractor reaches first, because a failed compressor, a refrigerant leak at the coil, or a seized fan motor will each stop the system in its own recognizable way.
Inside, the air handler or indoor coil sits in a closet, attic, or mechanical room and works with the outdoor unit to move conditioned air into the living space. The reversing valve, the expansion device, and the refrigerant lines that connect both units are also part of what a contractor traces when the system is not performing as it should.
The drawing shows a typical heat pump layout, and a licensed contractor determines which components apply to the specific equipment and configuration in your home.
