A contractor quoting a heat pump installation in Logan County has to settle the sizing question before anything else, and what the county's weather history tells them is useful but not alarming. 92 severe weather events were recorded in Logan County, Kentucky between 2015 and 2024. At roughly that rate, severe weather is a real variable in the operating life of equipment here, present enough that a contractor accounts for it in the load calculation, but not so relentless that it overrides everything else. Duct layout, how well the house holds conditioned air, and how the system is commissioned on the day of install are what determine whether a heat pump in this county performs as sized or runs short of it for years.
Ductwork laid in for a furnace or a window unit was sized and routed for a different machine. Half the homes in Logan County, Kentucky were built in 1978 or earlier (2020-2024 ACS 5-year). A contractor coming in to install a heat pump has to check whether what is already in the walls and ceilings can carry the airflow the new system requires, because if it cannot, the ductwork becomes part of the job whether the homeowner priced for it or not. The electrical panel faces the same question: what a heat pump draws is not what the house was wired to supply.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece most homeowners notice first. It sits on a pad beside the house and holds the compressor and the outdoor coil, the two components that do the heaviest work in the system. Inside, the air handler mounts in a utility space, a closet, or an attic and moves conditioned air through the home.
A refrigerant line set runs between the two units, carrying the working fluid back and forth through insulated copper tubing. A thermostat goes on an interior wall where it reads the house temperature and signals the system to run.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house.

Severe Weather Events in Logan County
Weather extremes put direct pressure on heating and cooling equipment, shortening cycles, raising run times, and accelerating wear. How hard a heat pump works over its life is largely a local question, and the pattern of severe weather in this area is part of that answer.
