Sizing a central AC system for Taylor County requires more than pulling a model number from a spec sheet. 106 severe weather events were recorded in Taylor County, Kentucky between 2015 and 2024. A contractor who ignores that record and installs to a generic regional baseline risks putting in equipment that runs harder than it was sized for, shortening its useful life before the first warranty period closes. Ductwork layout, unit placement, and equipment grade all have to be matched to what this area actually demands, and a contractor familiar with the county will price and spec the job on that basis.
Ductwork laid down for equipment from a different era carries assumptions about airflow, routing, and load that a new central AC system will immediately run up against. Half the homes in Taylor County, Kentucky were built in 1978 or earlier (2020-2024 ACS 5-year). That history shows up on an installation job in the form of ducts that may be undersized for modern equipment, poorly sealed at joints, or routed in ways that add resistance a new unit has to fight. The electrical service in houses of that vintage is worth checking too, since the draw a new system requires can exceed what an older panel was wired to supply. A licensed contractor working in Taylor County prices the ductwork and the electrical before the unit, because those are what the installation turns on.
What Gets Installed With a New Central AC
The outdoor unit sits on a concrete pad beside the house and holds the compressor and condenser coil. Inside, the air handler or furnace-and-coil assembly mounts in a utility space, basement, or closet and moves conditioned air through the home. These two units are what a homeowner is buying when they commission a central AC installation.
A copper refrigerant line set runs between the indoor and outdoor units, connecting them through an exterior wall. The thermostat goes on an interior wall where it reads the home's temperature and tells the system when to run. A condensate drain line carries moisture pulled from the air to a floor drain or outside.
The drawing shows a typical layout, and a licensed contractor determines exactly what the installation requires 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.
