A heat pump in McLean County that needs repair is more likely failing because of how it was installed or how long it has been running than because of what the weather has put it through. 71 severe weather events were recorded in McLean County, Kentucky between 2015 and 2024. At that rate, severe weather is an occasional fact of life here, not a standing mechanical burden, and a contractor who attributes a failed compressor or a refrigerant problem to storm load is reaching past the more probable causes. Age-related wear on the reversing valve, a capacitor at the end of its service life, or a refrigerant charge that was never set correctly at install will account for most of what contractors find when they open these systems up.
Ductwork that has carried conditioned air since before residential heat pumps were common carries a repair history a contractor has to read component by component once the unit is open. Half the homes in McLean County, Kentucky were built in 1976 or earlier (2020-2024 ACS 5-year). Equipment installed into houses of that age has often been through multiple service cycles, and what the compressor, reversing valve, and refrigerant circuit show on inspection reflects that accumulated load. A repair quote that treats the unit as a known quantity before it is opened is likely to move once the actual condition of those components is seen.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is where most repairs begin. It sits outside the house and holds the compressor, which is the heart of the system, along with the outdoor coil and a fan that moves air across it. When a heat pump stops heating or cooling, the compressor and that coil are among the first things a contractor puts hands on.
Inside the house, the air handler contains the indoor coil, a blower fan, and the expansion valve that controls refrigerant flow between the two units. The refrigerant lines connecting the two units and the reversing valve inside the outdoor cabinet are also common fault points when the system runs but performs poorly.
The drawing shows a general layout of these components, and a licensed contractor determines what applies to the specific equipment and configuration in your home.

Severe Weather Events in McLean County
Weather puts direct stress on heat pump equipment, and McLean County's climate shapes how hard that equipment works and how often it needs repair. A pattern of local storm activity is a load fact, not background color, which is why it belongs on a page about keeping that equipment running.
