Takes about a minute. No obligation.
A contractor quoting a central AC installation in Crittenden County has to work out what the local climate actually asks of equipment before settling on a system size or a spec. 63 severe weather events were recorded in Crittenden County, Kentucky between 2015 and 2024. At that rate, severe weather is real but not relentless, and a system's long-term performance here lands more squarely on how it was sized and how well it was set up than on storm load. A loose refrigerant charge, undersized ductwork, or a unit placed in poor airflow will cost the homeowner more over years than the weather record will.
Ductwork laid in for earlier generations of equipment does not automatically carry a modern central AC system. Half the homes in Crittenden County, Kentucky were built in 1975 or earlier (2020-2024 ACS 5-year). A contractor sizing a new unit here has to assess whether the existing trunk lines and branch runs move the volume the new equipment expects, and whether the electrical service supports the load. If the ducts fall short, the installation scopes around them or through them. The box on the truck is the straightforward part of the job; what is already in the walls is where the real assessment happens.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a pad outside the house and holds the compressor and the condenser coil, the two components that do the heaviest work in the refrigeration cycle. Inside, the air handler or furnace-based coil cabinet mounts in a utility space, basement, or closet and connects to the supply and return sides of the duct system.
The evaporator coil fits inside or directly above the air handler and is where the air in your home passes across the refrigerant lines. A copper or aluminum refrigerant line set runs between the indoor and outdoor units, and a condensate drain line carries moisture away from the coil to a floor drain or outside the building.
The drawing shows a standard layout, and a licensed contractor determines exactly what applies to this house.

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.
