A central AC installation in Scott County has to be sized for a climate that does throw genuine severe weather at equipment, but not at a rate that makes it the standing pressure on every system here. 84 severe weather events were recorded in Scott County, Kentucky between 2015 and 2024. At that level, severe weather is an occasional variable rather than a constant one, and a contractor quoting a new installation is not designing around a punishing baseline. What matters more is getting the equipment sized correctly for the home and installed to the kind of standard that survives the seasons regardless of what any given summer brings.
Ductwork laid in a house built in the recent era was sized for systems close to what a contractor installs today, which changes where the real evaluation goes. Half the homes in Scott County, Kentucky were built in 2000 or earlier (2020-2024 ACS 5-year). That means the electrical service and the duct layout a contractor finds in a Scott County home are more likely to be workable than they would be in stock built for an earlier generation of equipment. The question a contractor has to answer is fit and load, not whether the infrastructure was built for something categorically different.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad along a side or rear wall, and it holds the compressor and the condenser coil. Inside, the air handler or furnace cabinet stands in a utility space, basement, or closet and moves conditioned air through the home. These two cabinets are the core of what a contractor brings to a new installation.
A copper refrigerant line set runs between the outdoor unit and the indoor cabinet, connecting the two halves of the system through an exterior wall. A thermostat mounts on an interior wall and gives the homeowner control over when the system runs. The drain line and condensate components also get set during installation, routed to carry moisture away from the indoor cabinet.
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.

Severe Weather Events in Scott County
Local weather puts real stress on cooling equipment, and how hard a system works over its life is shaped by what the climate around it actually does. That makes installation sizing and equipment selection a local decision, not a generic one.
