A contractor quoting a heat pump installation in Clark County has to size the system around what the house actually needs, and the weather record here does not change that calculus the way it might in a county where severe conditions are a constant. 67 severe weather events were recorded in Clark County, Kentucky between 2015 and 2024. At roughly that rate, severe weather is a real but periodic feature of life here, not a grinding background load that wears equipment down before anything else can. What that means for installation is that duct condition, insulation, and load calculations on the structure drive the spec. A system sized right for this house will carry the climate without being overbuilt for it.
Ductwork laid in for older heating systems was designed around different airflow volumes than a heat pump moves, and in a county where that gap is as wide as it is here, what a contractor finds in the walls and ceiling can reshape the whole scope of the job before the new unit is even ordered. Half the homes in Clark County, Kentucky were built in 1979 or earlier (2020-2024 ACS 5-year). That vintage of ductwork often runs at duct diameters and layouts that restrict the airflow a heat pump needs to perform at its rated capacity, which means a contractor has to assess the existing runs, not just measure the space. The electrical service is a separate question, since panel capacity for a heat pump draw depends on what has or has not been upgraded since the house was built.
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 one set of coils. Inside, the air handler mounts in a utility space, closet, or attic and contains the blower fan and the second set of coils that condition air before it moves through the house.
A refrigerant line set runs between the two units, carrying the working fluid back and forth through insulated copper tubing. The thermostat goes on an interior wall where the homeowner sets temperatures and the system responds. A condensate drain line runs from the air handler to carry away moisture collected during operation.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house.
