A contractor sizing a heat pump for Carter County spends more time on the house itself than on the weather outside it. Duct layout, insulation, and the quality of the previous install shape what equipment the job needs. 57 severe weather events were recorded in Carter County, Kentucky between 2015 and 2024. At that rate, severe weather is an occasional event, not a steady operating load, so a failed system or a struggling one almost certainly has another explanation. A contractor who attributes poor performance to storm exposure here is working backward. The installation variables are where the real sizing decisions live.
Ductwork laid down for a different era of heating runs through a large share of Carter County homes, and whether those ducts can carry what a heat pump needs is what a contractor has to settle before anything else on an installation job. Half the homes in Carter County, Kentucky were built in 1984 or earlier (2020-2024 ACS 5-year). That spread means a contractor sizing a system here checks static pressure, duct diameter, and the condition of existing runs before the equipment choice is final. Electrical service follows the same logic: panels in older stock were sized for different loads, and a heat pump draw may require an upgrade. The duct and electrical assessments together are what determines the real scope of the job.
What Gets Installed With a New Heat Pump
The outdoor unit sits on a pad beside the house and holds the compressor and the coil that exchange heat with the outside air. Inside, the air handler mounts in a utility space, closet, or attic and moves conditioned air through the home. These two units are the core of what a contractor puts in place.
A refrigerant line set runs between the outdoor unit and the air handler, carrying refrigerant through insulated copper tubing. A thermostat goes on an interior wall where it reads the living space and signals the system to run. Some installs also include a condensate drain line routed from the air handler to a suitable discharge point.
The drawing shows a representative layout, and a licensed contractor determines exactly how each piece fits the conditions in your house.
