A contractor quoting a heat pump installation in Ohio County has to account for the climate before settling on equipment size or refrigerant line routing, but the weather record here does not tell a story of relentless punishment. 87 severe weather events were recorded in Ohio County, Kentucky between 2015 and 2024. At roughly that pace, severe weather is a real variable in the life of any system, not a constant battering. A sloppy installation will still fail on its own schedule, and the contractor's job is to get the sizing and the line work right so that ordinary seasonal load, not shortcuts, determines how long the equipment runs.
Ductwork laid down for a furnace and window units was not designed around the airflow a heat pump needs, and in Ohio County much of that ductwork has never been touched since the house was built. Half the homes in Ohio County, Kentucky were built in 1984 or earlier (2020-2024 ACS 5-year). That puts the existing duct runs at the center of any installation quote: a contractor has to assess whether the layout and condition will carry the new system before the equipment itself is priced. The electrical service gets the same scrutiny, since a heat pump draws differently than what those panels were originally 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, an air handler mounts in a utility space, a closet, or an attic, and it pushes conditioned air through the home.
A refrigerant line set runs between the two units, connecting the outdoor pad to the air handler. A thermostat mounts on an interior wall and gives the homeowner control over the whole system. An expansion valve, tucked inside the air handler, regulates refrigerant flow between the two coils.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house.
