A contractor quoting a central AC installation in Bath County has to size the system for what this area actually puts equipment through, and that starts with the weather record. 133 severe weather events were recorded in Bath County, Kentucky between 2015 and 2024. At that rate, severe weather is part of the normal operating life of a system here, so a contractor who sizes or specs the job the same way they would for a calmer region is setting the equipment up to run harder than it was planned for. Refrigerant line routing, unit placement, and equipment ratings all carry more weight on an install in a county with a record like this.
Ductwork laid down for an older system carries assumptions about airflow, routing, and return placement that a modern central AC unit does not share. Half the homes in Bath County, Kentucky were built in 1984 or earlier (2020-2024 ACS 5-year). That gap is what a contractor has to settle before anything else on an installation job: whether the existing duct layout will actually move air the way the new equipment requires, or whether sections of it need to be rerouted or replaced. The electrical service gets the same look, since the load a current unit draws may exceed what the panel was wired to supply.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a concrete pad outside the house and holds the compressor and condenser coil, which together shed heat to the outside air. Inside, the air handler or furnace cabinet stands in a utility space, basement, or closet and holds the evaporator coil that pulls heat from the air moving through it. These two units are the heart of the installation.
A copper refrigerant line set runs between the indoor and outdoor units, and a condensate drain line carries moisture away from the evaporator coil to a floor drain or outdoors. The thermostat mounts on an interior wall and is the only piece a homeowner touches day to day, sending signals that tell both units when to run.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the conditions in your house.

What the Installation Actually Looks Like
Split-system central air conditioners rated below 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners rated at or above 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners manufactured between January 1, 2015 and December 31, 2022 had to meet 13 SEER, the metric that preceded SEER2.
Single-package central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Space-constrained central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 11.7 SEER2.
Federal efficiency standards for split-system central air conditioners and heat pumps are set on each certified combination of outdoor unit and indoor coil rather than on the outdoor unit alone.
Residential and light commercial air conditioning and heat pump systems assembled in the field, including mini-splits and unitary systems, may not be installed on or after January 1, 2025 using a refrigerant with a global warming potential above 700.
A field-assembled system whose specified components were all manufactured or imported before January 1, 2025 carries no installation compliance date under the refrigerant restrictions and may still be installed.
