A contractor quoting a central AC installation in Henry County has to get the sizing right for this specific structure before anything else, because a mis-sized system fails on its own terms regardless of what the weather does. 66 severe weather events were recorded in Henry County, Kentucky between 2015 and 2024. At roughly that rate, severe weather here is real but infrequent enough that it does not drive installation decisions the way a persistently punishing climate would. What drives them instead is the load profile of the house itself, how well the ductwork is laid out, and whether the equipment is matched to the square footage. A contractor who skips that work and relies on a catalog selection leaves the homeowner with a system that runs short or long before the first summer is out.
Ductwork laid down for an older system carries assumptions about airflow, routing, and load that a new central AC unit does not share. Half the homes in Henry County, Kentucky were built in 1977 or earlier (2020-2024 ACS 5-year). A contractor installing central AC in a house from that era has to establish whether the existing duct layout will actually deliver conditioned air where the new system expects to push it, and whether the electrical service can handle the draw. If either is undersized or routed in a way that chokes the new unit, the equipment choice becomes secondary to solving what the house already has in it.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad along an exterior wall, and houses the compressor and condenser coil. Inside, the air handler or furnace-mounted evaporator coil sits in a utility space, basement, or closet and is the indoor half of the system. These two pieces are what a homeowner is buying.
The refrigerant line set runs between the outdoor and indoor units, connecting them through a small penetration in the wall. A thermostat goes on an interior wall where it reads the living space and signals the system to run. The condensate drain line carries moisture out from the indoor coil to a floor drain or exterior point.
The drawing shows a typical layout, and a licensed contractor determines what fits the actual configuration of your home.

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.
