Sizing central AC in Lee County starts with what the house actually demands, not with a storm calendar. 60 severe weather events were recorded in Lee County, Kentucky between 2015 and 2024. At that rate, severe weather is an event here, not a steady operating pressure, and a contractor who blames the climate for an undersized or poorly installed system is reaching past the likeliest explanations. What decides whether a new system performs is how accurately the load is calculated for the structure, how well the equipment is matched to it, and how cleanly the install is executed. Those are the variables a contractor has to get right before the first season runs.
Ductwork sized and routed for an older system carries assumptions a new central AC unit may not share: airflow paths, return placement, and trunk dimensions that were never drawn with today's equipment in mind. Half the homes in Lee County, Kentucky were built in 1988 or earlier (2020-2024 ACS 5-year). A contractor quoting a central AC installation in a house this age measures what is already in the walls before pricing the unit, because the duct layout determines what the new system can actually deliver once it runs. Where the existing ductwork cannot handle the new airflow demands, the installation scope grows beyond the equipment itself.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and houses the compressor and condenser coil. Inside, the air handler or furnace-mounted evaporator coil lives in a utility space, basement, or attic and is the indoor half of the system. Together these two units are what a Central AC installation puts in place.
The refrigerant line set runs between the two units, typically through a wall or up through a chase, and the thermostat mounts on an interior wall where it reads the temperature of the living space and signals the system to run. A contractor also connects the system to a dedicated circuit at the electrical panel, though the panel work itself is handled separately.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the conditions in your house.

What HVAC Installation Looks Like in Lee 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.
Licensing Rules in Lee County, Kentucky
Kentucky requires a licence to practise heating, ventilation and air conditioning contracting: a person may not do the work unless they have met the state licensing requirements.
Severe Weather in Lee County
Weather puts a load on cooling equipment, and that load is shaped by what actually happens in this part of Kentucky. A central AC system sized and installed for local conditions holds up better than one built to a generic spec.
