A contractor quoting a central AC install in Cross County has to get the load calculation right before anything else, because the equipment will not get much rest once it starts. Homes in Cross County, AR run cooling about five months a year, from May through September. The compressor and condenser fan cycle through that entire stretch, and a unit that is even slightly undersized runs longer on each call, building wear faster than the manufacturer's ratings assume. Sloppy refrigerant charging or a duct system that does not match the unit makes the same problem worse. A correctly sized, properly commissioned system earns its cost here in ways it would not somewhere the summers are short.
Ductwork sized and routed for equipment that has since been replaced at least once is what a contractor finds in a large share of Cross County homes. Half the homes in Cross County, Arkansas were built in 1981 or earlier (2020-2024 ACS 5-year). That history matters on an installation job because a new central AC unit draws on what the house already has, and ducts laid out for something older may not move air the way the new system needs. An electrician may flag the same issue on the service panel side. Those two variables, the existing duct runs and the electrical supply, are where the installation scope gets settled, before the equipment itself is ever priced.
What a Central AC System Includes
The outdoor condenser unit sits on a concrete pad outside the house and holds the compressor and condenser coil, which together release heat drawn from inside. The indoor air handler or furnace-mounted evaporator coil sits inside, most often in a utility closet, basement, or attic, and is the point where warm indoor air passes across refrigerant lines.
A refrigerant line set runs between those two units, connecting the indoor and outdoor sides through the wall or floor. The thermostat goes on an interior wall and is the control point for the whole system, telling it when to run and when to stop.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to 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.
