Sizing and quoting a central AC install in Edmonson County starts with the house, not the forecast. 75 severe weather events were recorded in Edmonson County, Kentucky between 2015 and 2024. At that rate, severe weather lands here from time to time, but a system in this area spends most of its life running against ordinary summer heat rather than storm load. A contractor who quotes for this county prices the install around duct layout, load calculations, and the structure of the house. Age and installation quality are what determine how a system holds up here, and a well-sized, properly installed unit does not need to be engineered around a weather threat that arrives infrequently.
Ductwork laid down for an older system carries assumptions about static pressure, room loads, and supply sizing that a new central AC unit will test on day one. Half the homes in Edmonson County, Kentucky were built in 1990 or earlier (2020-2024 ACS 5-year). A contractor pricing an installation here has to assess whether those runs can move the air a modern system pushes, or whether sections need to be resized, resealed, or replaced before the new equipment goes in. The electrical service matters too, but ductwork is where the scope surprises tend to live.
What Gets Installed With a New Central AC
The outdoor unit, called the condenser, sits on a pad outside the house and holds the compressor and condenser coil. Inside, the air handler or furnace-and-coil assembly lives in a mechanical room, basement, or attic and pushes conditioned air into the duct system. These are the two main pieces a homeowner is buying.
The refrigerant line set runs between the outdoor and indoor units, connecting the two sides of the system. A thermostat mounts on an interior wall and gives the homeowner control over the whole system. The condensate drain line runs from the indoor coil to a floor drain or outdoors, carrying away moisture pulled from the air.
The drawing shows a typical layout, and a licensed contractor determines what fits the specifics of this 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.
