A contractor sizing or installing a heat pump in Anderson County has to work out what the system will actually face over its life here, and the weather record is one input to that. 66 severe weather events were recorded in Anderson County, Kentucky between 2015 and 2024. At that rate, severe weather is real but not a relentless load, and a contractor who blames a failing system on the climate is reaching. Age of the equipment and the quality of the original installation explain most of what goes wrong in a county like this. Sizing the new unit correctly for the house it serves matters more than armoring it against conditions it will rarely meet.
Ductwork laid down for a gas furnace or a window unit moves air on a different schedule than a heat pump requires, and in Anderson County a lot of it does exactly that. Half the homes in Anderson County, Kentucky were built in 1989 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump installation here opens the duct runs and measures what they will actually carry before the equipment gets priced, because ductwork that underperforms will limit what any new unit delivers regardless of its efficiency rating. The electrical panel gets the same look, since the service a house was wired for and what a heat pump draws are two separate questions.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece most homeowners notice first. It sits on a pad outside the house and holds the compressor and the outdoor coil, which do the core work of moving heat between the refrigerant and the outside air. Inside, the air handler mounts in a utility space, attic, or closet and circulates conditioned air through the home.
A refrigerant line set runs between the two units, carrying refrigerant back and forth through insulated copper tubing that a contractor routes along the exterior or through interior walls. A thermostat goes on an interior wall where it reads the home's temperature and tells the system when to run.
The drawing shows a typical layout, and a licensed contractor determines what applies to this specific house.
