A contractor quoting a central AC installation in Breckinridge County has to account for what the climate here actually demands before settling on equipment size or placement. 124 severe weather events were recorded in Breckinridge County, Kentucky between 2015 and 2024. At that rate, severe weather is a standing condition of operating in this county, not an occasional outlier, and it shapes how a system gets sized. A unit that fits a catalog recommendation for a milder area will run harder and longer here to keep up. Contractors factor that load into refrigerant line routing, equipment grade, and rated capacity from the first visit.
Existing ductwork is what a contractor sizes the job around, and in Breckinridge County that ductwork has a history worth accounting for. Half the homes in Breckinridge County, Kentucky were built in 1990 or earlier (2020-2024 ACS 5-year). Houses built by then were laid out for the equipment of that era, and the duct runs, trunk lines, and returns were sized accordingly. A new central AC system draws on all of it. If the ductwork cannot carry the airflow a modern unit needs, the installation scope changes before the new equipment is ever set in place.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a concrete pad outside the house and holds the compressor and condenser coil, which are the mechanical core of the system. Inside, the air handler or furnace-based evaporator coil assembly mounts in a utility space, basement, or closet and is where treated air enters the duct system.
A refrigerant line set runs between the two units, linking the indoor and outdoor sides through the wall or floor. The thermostat mounts on an interior wall and gives the homeowner direct control over when the system runs and what temperature it holds.
The drawing shows a typical layout, and a licensed contractor determines exactly what fits and where in your specific 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.
