Sizing a heat pump for Franklin County is a local calculation, not a catalog one. 74 severe weather events were recorded in Franklin County, Kentucky between 2015 and 2024. At that rate, severe weather is a standing feature of the operating environment, which means a contractor has to size for real peak demand rather than regional averages. A system undersized against this climate will run harder, cycle longer, and wear its compressor faster than the specs suggest. A contractor quoting a replacement or a new install here starts with a manual load calculation built around what this area actually asks of the equipment.
Ductwork laid down for an older furnace carries air at pressures and volumes a heat pump does not always match, and the gap between what the ducts were built to move and what a heat pump needs to deliver shows up in the sizing and sealing work a contractor has to do before the new unit runs right. Half the homes in Franklin County, Kentucky were built in 1977 or earlier (2020-2024 ACS 5-year). That means the electrical panel is one question a contractor opens, but the duct layout is often the longer conversation, because air that loops through undersized or poorly sealed runs cannot be fixed by the equipment alone.
What Gets Installed With a New Heat Pump
The outdoor unit sits on a pad beside the house and holds the compressor and coil that do the core work of the system. Inside, an air handler mounts in a mechanical room, closet, or attic and moves conditioned air through the home. These two units are what a homeowner is buying when they buy a heat pump.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two halves of the system through the wall or roof. A thermostat goes on an interior wall and gives the homeowner control over the whole setup. Some installations also include an auxiliary heat strip inside the air handler for the coldest stretches of winter.
The drawing shows a typical layout, and a licensed contractor determines what applies to this particular house.

Severe Weather Events in Franklin County
Franklin County's climate puts real demands on heating and cooling equipment year after year. A heat pump sized and installed for local conditions handles those demands differently than one spec'd for somewhere else, which is why the weather record here is part of the picture.
