A contractor quoting central AC installation in Fulton County has to decide how hard the local climate will actually work the new equipment, because that shapes the sizing call before anything else. 83 severe weather events were recorded in Fulton County, Kentucky between 2015 and 2024. At that rate, severe weather is a genuine background condition rather than a rare exception, but it is not frequent enough to make storm resilience the controlling factor in how a system gets specified. The load is steady rather than punishing, which means the contractor's sharpest decisions are about correct sizing for the cooling demand and the quality of the refrigerant lines, ductwork connections, and airflow setup. A loose or undersized install degrades faster here than it would somewhere the system barely runs.
Ductwork laid for the equipment of an earlier generation was sized and routed for that equipment, not for what a contractor is installing today. Half the homes in Fulton County, Kentucky were built in 1972 or earlier (2020-2024 ACS 5-year). That gap is where most of the real work in a central AC installation lives: a contractor has to determine whether the existing ducts can move the air a new system will push, and whether the electrical service will carry the load. If either falls short, the installation scopes out differently than a straight equipment swap.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a pad beside the house and holds the compressor and condenser coil, the two components that handle the heat pulled from inside. The indoor air handler or furnace-mounted evaporator coil lives in a closet, attic, or basement and is the other half of that pairing. Both units together make up what a homeowner is buying.
The refrigerant line set runs between the two units, connecting them through a wall or floor, and the thermostat mounts on an interior wall where it reads the indoor temperature and tells the system when to run. A condensate drain line also runs from the indoor coil to a nearby drain, carrying away the moisture the coil pulls from the air.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the setup in your 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.
Licensing Rules for HVAC Work in Fulton 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 Fulton County
Weather extremes put real demand on heating and cooling equipment, and what a system faces in Fulton County shapes how it should be sized and specified. That makes local conditions a practical part of any central AC installation decision.
