A contractor quoting a heat pump install in Knott County has to account for what the local climate actually demands before settling on equipment or configuration. 54 severe weather events were recorded in Knott County, Kentucky between 2015 and 2024. At that rate, severe weather is a standing condition of operation here, not an occasional interruption, and a system sized or mounted as though the environment were mild will be undersized for what it faces. That means the contractor's choices about unit capacity, placement, and refrigerant line routing are local judgments, shaped by how hard this area pushes equipment year after year.
Ductwork laid for older heating systems was sized and routed for a different kind of airflow, and electrical service was run for different loads. Half the homes in Knott County, Kentucky were built in 1982 or earlier (2020-2024 ACS 5-year). A heat pump places specific demands on both, and in housing of this vintage a contractor often finds that the existing duct layout restricts return air in ways that matter for system performance. The electrical service may need assessment before anything else is priced. What the house already contains is what decides how the installation goes.
What Gets Installed With a New Heat Pump
The outdoor unit sits on a concrete pad outside the house and holds the compressor and one set of coils. Inside, an air handler or indoor coil assembly mounts in a utility space, basement, or closet and pairs with a blower to move conditioned air through the home. These two units are what a homeowner is buying.
A refrigerant line set runs between the outdoor and indoor units, connecting the two through a wall or floor penetration. A thermostat goes on an interior wall where it reads the living space and tells the system when to run. Some installs also include a secondary thermal expansion valve or a reversing valve assembly housed inside the outdoor cabinet.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece is positioned and connected in your house.

Severe Weather Events in Knott County
Weather conditions place real demand on heating and cooling equipment, and that demand is local. A heat pump sized and installed for this county's pattern of weather stress will hold up differently than one specified somewhere else.
