Sizing a central AC unit in Cleburne County is not a generic calculation. The compressor, the condenser fan, and the contactor all carry the load of a true summer, and a system that is undersized by even a modest margin starts each cycle already working harder than it should. Homes in Cleburne County, AR run cooling about four months a year, from June through September. A contractor running a load calculation here has to get the square footage, insulation, and duct condition right before committing to a unit size, because the compressor will log real operating hours across those months and wear will accumulate on the parts that cycle most.
Ductwork laid out for older equipment does not automatically carry a modern central AC system without a contractor first checking whether the runs, returns, and sizing match what a new unit actually needs. Half the homes in Cleburne County, Arkansas were built in 1989 or earlier (2020-2024 ACS 5-year). That puts a meaningful share of the housing stock in a range where the ducts were built around something different from what a contractor is now being asked to install, and where the electrical service may reflect the same era of design. Before any equipment gets priced, the ductwork gets evaluated. Where it falls short, the scope of the install grows around that finding.
What a Central AC System Includes
The outdoor condenser unit sits on a pad outside the house and holds the compressor and condenser coil, which together handle the heat side of the system. Inside, the air handler or furnace cabinet mounts in a utility space, attic, or basement and moves air across the evaporator coil housed within it. These two units are what a contractor brings in and sets into place.
A copper refrigerant line set runs between the indoor and outdoor units, connecting them so the system works as one. A thermostat goes on an interior wall and gives the homeowner control over the whole system. The condensate drain line runs from the indoor cabinet to a suitable drain point, carrying away the moisture the coil pulls from the air.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house and its existing setup.

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.
