A contractor quoting central AC installation in Madison County is not solving a generic sizing problem. 125 severe weather events were recorded in Madison County, Kentucky between 2015 and 2024. At that rate, severe weather is a standing feature of the climate a new system will run against, not an edge case. Sizing has to account for that load, and so does the quality of every connection, mounting point, and refrigerant line. A unit spec'd to median conditions and installed to minimum standard will be working against the actual climate from its first summer.
Ductwork laid down for an earlier generation of equipment carries assumptions about airflow and routing that a new central AC system does not share. Half the homes in Madison County, Kentucky were built in 1993 or earlier (2020-2024 ACS 5-year). A contractor pricing an installation here has to assess whether the existing trunk lines and branch runs will move the volume a modern unit pushes, and whether the electrical service at the panel supports the draw. If either falls short, that work gets priced and scheduled before the equipment question is settled.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and holds 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. Together these two pieces make up the core of what a contractor puts in.
The thermostat goes on an interior wall where it reads the temperature of the living space and tells the system when to run. A contractor also installs the refrigerant line set, a pair of copper lines that run between the indoor and outdoor units and carry refrigerant between them.
The drawing shows a typical layout, and a licensed contractor determines exactly how these pieces are configured in your home.

What HVAC Installation Looks Like in Madison County
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.
