A contractor quoting a heat pump installation in Harlan County is not working from a catalog spec sheet alone. 92 severe weather events were recorded in Harlan County, Kentucky between 2015 and 2024. At that rate, severe weather is a standing condition of the operating environment, and a system sized without accounting for it will be working against its own design limits from the first season. Refrigerant line placement, mounting, and load calculations all look different once that pressure is built into the job from the start.
Ductwork laid in for an older heating system carries assumptions about airflow, pressure, and return paths that a heat pump does not share. Half the homes in Harlan County, Kentucky were built in 1976 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump installation in stock this old is not pricing the unit first; the duct system gets measured and assessed before the equipment selection goes anywhere, because what the ducts can and cannot carry sets the boundary on what a new system can actually do in that house. Electrical service comes next, since heat pump equipment draws differently than what much of this stock was wired to handle.
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 one set of coils. Inside, the air handler mounts in a utility closet, basement, or attic and moves conditioned air through the home's supply registers.
A refrigerant line set runs between the two units, connecting the outdoor pad to the air handler and carrying the working fluid between them. A thermostat goes on an interior wall and gives the homeowner control over the whole system.
The drawing shows a representative layout, and a licensed contractor determines what applies to the specific house and setup.

Severe Weather Events in Harlan County
Weather extremes put direct pressure on heating and cooling equipment, shortening run cycles, raising demand, and accelerating wear. How hard a heat pump has to work in Harlan County is a local question, and the record below gives that question a factual foundation.
