A heat pump repair call in Washington County usually comes down to two questions: what is worn out, and why. 66 severe weather events were recorded in Washington County, Kentucky between 2015 and 2024. At that rate, severe weather is a real but occasional part of operating life here, not a standing condition that grinds through every component. A contractor will typically find that refrigerant leaks, failing capacitors, and compressor wear trace back to the age of the unit and how well it has been serviced rather than to storm exposure. The weather record belongs in the picture, but maintenance history is what decides the repair scope.
Older wiring and original line sets are what a contractor opens up to in much of this county, and what they find inside a heat pump that has been running in a house of this vintage often decides how far the repair goes. Half the homes in Washington County, Kentucky were built in 1982 or earlier (2020-2024 ACS 5-year). A system installed into infrastructure from that era has been working against connections, contacts, and refrigerant pathways that were never designed for modern equipment. When a compressor or reversing valve fails, the repair scope depends on whether the surrounding components are sound enough to make a new part last, and in stock this old, that is not a given.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit holds the compressor and the condenser coil, and it sits on a pad outside the house. The compressor is where most repair calls begin: when it fails, the system stops moving heat entirely. The condenser coil runs alongside it, and a damaged or dirty coil forces the compressor to work harder than it should.
Inside the house, the air handler contains the evaporator coil and the blower fan, usually tucked into a closet, attic, or utility room. The reversing valve, which lets the system shift between heating and cooling, sits in the outdoor unit and is a common point of failure when the system blows the wrong temperature. The expansion valve and the refrigerant lines connecting both units are also what a contractor checks when the system is running but not conditioning the air.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific setup.
