A contractor quoting a heat pump installation in Livingston County has to settle the sizing question locally, because what the equipment will be asked to carry is a site question, not a catalog default. 79 severe weather events were recorded in Livingston County, Kentucky between 2015 and 2024. At roughly that rate, severe weather is a real but infrequent factor in the operating life of a system here. That means the installation decisions that drive long-term performance are the ones a contractor controls directly: how well the ductwork is sealed, how the refrigerant lines are run, and whether the unit is matched to the actual load of the house. A system that fails early in this county almost always points back to those choices.
Ductwork laid down for an older heating system carries assumptions about airflow that a heat pump does not share. A heat pump moves air differently, at different volumes and pressures, and ducts that were routed and sized for something else may restrict that or distribute it unevenly through the house. Half the homes in Livingston County, Kentucky were built in 1978 or earlier (2020-2024 ACS 5-year). That puts the existing duct system at the center of what a contractor has to assess before the equipment choice can be settled. Electrical service gets looked at too, since a heat pump's draw has to be matched against what the panel actually carries.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, set on a pad beside the house, and it holds the compressor and the outdoor coil. Inside, the air handler mounts in a utility space, basement, or closet and moves conditioned air through the home. Together, these two units do the system's core work.
A refrigerant line set runs between the outdoor unit and the air handler, carrying the working fluid through both. A thermostat goes on an interior wall where it reads the home's temperature and tells the system when to run. The condensate drain line carries moisture pulled from the indoor air outside or to a drain.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the specifics of your house.

Severe Weather Events in Livingston County
Extreme weather puts heating and cooling equipment under real stress, and what the climate does in a given county shapes how hard a heat pump has to work year after year. Sizing and installing equipment for Livingston County means accounting for local conditions, not averages drawn from somewhere else.
