A contractor sizing a central AC system in Cumberland County is not reading a high-stress weather record. 49 severe weather events were recorded in Cumberland County, Kentucky between 2015 and 2024. At that rate, severe weather is an event here, not a standing condition, which means the load a system carries over its life is shaped far more by how well it was sized for the structure and how cleanly the install was done. A unit undersized at the time of installation will strain through every cooling season regardless of what the sky does.
Ducts laid down for the original equipment in a house this old were routed and sized around what that equipment needed, and a new central AC unit draws and distributes air on its own terms. Half the homes in Cumberland County, Kentucky were built in 1986 or earlier (2020-2024 ACS 5-year). A contractor installing a system here has to assess what those ducts will actually carry before the equipment selection means much. Electrical service follows the same logic: the panel that fed the old setup may or may not serve the new load. Those two things, the ductwork and the electrical, are what the job turns on in stock like this.
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-mounted evaporator coil lives in a utility space, basement, or closet. Together these two units are the core of what a contractor places and connects during an installation.
The thermostat mounts on an interior wall and gives the homeowner control over the whole system. A refrigerant line set runs between the indoor and outdoor units, and a condensate drain line carries moisture out of the house. Each of these gets routed during installation to suit the layout of the specific home.
The drawing shows a typical layout, and a licensed contractor determines what applies to your house.

What Happens During an HVAC Installation in Cumberland 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.

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 Cumberland County
Weather puts a direct load on cooling equipment: the harder the climate swings, the harder a system works to hold temperature. That workload shapes what gets installed here and how that equipment needs to be sized.
