A contractor quoting a heat pump installation in Letcher County has to solve a local sizing problem before anything else, and the weather record here shapes what that means. 71 severe weather events were recorded in Letcher County, Kentucky between 2015 and 2024. At that rate, severe weather is an event rather than a constant condition, which means the climate alone does not drive the job. What drives it is getting the load calculation right for the structure, choosing equipment matched to the actual heating and cooling demand of the house, and installing it so the refrigerant charge and airflow are correct from day one. A system that fails here is almost always undone by a poor install or a mismatch in capacity.
Ductwork sized and routed for older heating systems is what a contractor runs into in much of Letcher County's housing stock. Half the homes in Letcher County, Kentucky were built in 1979 or earlier (2020-2024 ACS 5-year). That timeline matters for installation because heat pumps move air differently than the equipment many of these houses were originally built around, and duct runs that were never designed for those demands can require modification before a new unit performs correctly. The electrical service gets checked for the same reason. What the house already contains sets the scope of the job.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first. It sits on a pad beside the house and holds the compressor and the outdoor coil, which together do the core work of moving heat in or out depending on the season. Inside, the air handler mounts in a utility space, closet, or attic and pushes conditioned air through the home.
A refrigerant line set runs between the two units, connecting them through the wall or floor. The thermostat mounts on an interior wall and gives the homeowner control over the whole system. Some installations also include a supplemental electric heat strip inside the air handler to cover the coldest days.
The drawing shows a typical layout, and a licensed contractor determines exactly what fits and connects in your house.

Severe Weather Events in Letcher County
Weather extremes put a measurable load on heating and cooling equipment, and that load shapes what a heat pump needs to handle over its life. Letcher County's conditions are local conditions, and the right installation accounts for them.
