A contractor quoting a central AC installation in Leslie County spends more time on the house than on the weather record. 60 severe weather events were recorded in Leslie County, Kentucky between 2015 and 2024. At that rate, severe weather lands here occasionally, not as a standing condition, so a system that has been struggling almost certainly has other explanations: undersized equipment, poor duct work, or an install that never matched the structure. What a contractor has to establish before selecting equipment is the actual load profile of the building, and that calculation runs on square footage, insulation, and window placement, not on storm history.
Ductwork laid down for an older system was sized for that system's airflow, its static pressure, and the equipment available at the time. Half the homes in Leslie County, Kentucky were built in 1984 or earlier (2020-2024 ACS 5-year). A contractor installing new central AC in a house from that era of the stock has to establish whether existing ducts can carry what a modern unit moves before the unit itself is ever priced. If the runs are undersized or the trunk layout does not match modern distribution needs, the ductwork becomes the job. The electrical is a separate check: service panels in housing of this age were not built to the draw a current-generation system expects.
What Gets Installed With a New Central AC
The outdoor unit, called the condenser, sits on a concrete pad or mounting brackets outside the house and holds the compressor and condenser coil. Inside, the air handler or furnace-based evaporator coil assembly sits in a utility closet, basement, or attic and connects to the supply and return ducts that run through the home.
The refrigerant lines are a paired set of copper tubes that run between the indoor and outdoor units, carrying refrigerant between the two. A thermostat mounts on an interior wall where it reads the air temperature and tells the system when to run.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house.

What happens when the contractor shows up
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 for Leslie 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 Events in Leslie County
Kentucky's climate puts real stress on cooling equipment, and what happens in Leslie County shapes how hard a central AC system has to work and how long it holds up. That makes local weather history a practical input when sizing and installing equipment here.
