A heat pump failing in Letcher County is worth diagnosing carefully before a contractor reaches for weather as the explanation. 71 severe weather events were recorded in Letcher County, Kentucky between 2015 and 2024. At that rate, severe weather is an event here, not a steady operating condition, and most systems in the county have not been pushed hard by it. What a contractor is more likely to find when they open a unit is wear tied to age or to how the system was sized and set up at installation. Refrigerant loss, compressor fatigue, and electrical component failure in this area point there first.
Ductwork in a house put up when a heat pump was not the plan tends to carry the evidence of every system that ran through it since: crimped joints, deteriorated insulation, and connections that were adapted rather than designed. Half the homes in Letcher County, Kentucky were built in 1979 or earlier (2020-2024 ACS 5-year). A contractor opening a heat pump in stock like this is looking at refrigerant circuits and electrical terminations that may have been serviced several times over, and the question that decides the repair bill is whether the parts the existing unit takes are still manufactured. When they are not, the scope changes before the labor estimate does.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a pad beside the house and holds the compressor, which is the piece a contractor reaches for first when a heat pump stops doing its job. The coil wrapped around the inside of that cabinet and the fan that pulls air through it are both common failure points. Inside, the air handler mounts in a closet, attic, or mechanical room and pushes conditioned air through the house.
A refrigerant line set runs between the two units, and a fault anywhere along it shows up as poor performance at both ends. The reversing valve lives inside the outdoor unit and is the part that lets the system heat in winter and cool in summer. A failed reversing valve is often what a contractor finds when a heat pump blows the wrong temperature.
The drawing shows the general layout of these components, and a licensed contractor determines which of them applies to the repair needed in your particular house.
