A heat pump going into a Casey County home is being sized for a place where the grid between calm and severe tilts toward active. 77 severe weather events were recorded in Casey County, Kentucky between 2015 and 2024. A contractor quoting an install here has to account for that load from the start, because a unit sized for a gentler operating environment will be running near its limits on the days it matters most. Refrigerant line placement, unit mounting, and system capacity all get priced and spec'd around what the equipment will actually face, not around what a catalog default assumes.
Ductwork laid down for a different kind of system shapes what a heat pump installation actually involves here. Half the homes in Casey County, Kentucky were built in 1985 or earlier (2020-2024 ACS 5-year). That means a contractor pricing a new unit has to look at what the existing duct layout can move and where it loses it, before the equipment choice settles anything. A panel that served the original heating setup may also need evaluation before a heat pump can draw from it. The house's bones are the variable; the unit itself follows from what they can support.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece most homeowners see first. It sits on a pad beside the house and holds the compressor and the outdoor coil, which together do the work of moving heat between the refrigerant and the outside air. Inside, the air handler mounts in a utility space, attic, or closet and contains the indoor coil and the blower that pushes conditioned air through the home.
A refrigerant line set runs between the two units, carrying refrigerant back and forth through insulated copper tubing. A thermostat mounts on an interior wall and gives the homeowner control over the system. Some installations also include a supplemental electric heat strip inside the air handler, which a contractor fits to the unit before it goes in.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific house.

Severe Weather Events in Casey County, Year by Year
