Sizing a central AC system for a Fulton County home is not a calculation a contractor can borrow from another county and adjust. Homes in Fulton County, AR run cooling about four months a year, from June through September. The compressor starts and stops through that full stretch, and the condenser fan and contactor cycle with it every day the temperature climbs. A system that is undersized will run longer on each of those days, loading the compressor harder than the manufacturer's duty cycle assumes. A contractor quoting an installation here has to get the load calculation right, because sloppy work shows up fast when the equipment gets little time off.
Ductwork sized for a previous system does not automatically carry a new one at the same pressure and volume a modern central AC unit needs. Half the homes in Fulton County, Arkansas were built in 1986 or earlier (2020-2024 ACS 5-year). That means a contractor installing a new system here has to assess what the existing ducts were built to move before anything else in the job can be quoted accurately. If the ductwork passes, the electrical service is the next question. Both have to line up with what the new equipment draws, and in stock this age those two things are checked, not assumed.
What a Central AC System Includes
The outdoor condenser unit sits on a pad outside the house and holds the compressor and the condenser coil. The indoor air handler, or furnace with an evaporator coil mounted above it, lives in a utility space, basement, or attic. Together these two units make up the core of the system a contractor brings to the job.
A refrigerant line set runs between the indoor and outdoor units, carrying refrigerant through insulated copper tubing. The thermostat mounts on an interior wall and serves as the control point for the whole system. A condensate drain line runs from the indoor coil to a nearby drain, clearing the moisture the coil pulls from the air.
The drawing shows a typical layout, and a licensed contractor determines exactly which components and configurations apply to your home.

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.
