Sizing a central AC system for this county starts with what the compressor is going to be asked to carry. Homes in Woodruff County, AR run cooling about five months a year, from May through September. A compressor that is undersized for the house it serves will run longer cycles and start more often across that load, and the contactor and condenser fan share that same accumulation. A contractor quoting a new install here has to run a full load calculation on the house before settling on equipment, because a unit that might coast in a shorter season will fall short here before its time.
Ductwork sized and routed for an earlier generation of equipment does not automatically carry a modern central AC system, and in Woodruff County that gap between what the house has and what a new unit needs is where installation jobs get complicated. Half the homes in Woodruff County, Arkansas were built in 1977 or earlier (2020-2024 ACS 5-year). Ducts laid out for older, lower-efficiency equipment often run at dimensions and configurations a current system cannot use as-is. A contractor pricing a new central AC installation here will measure and pressure-test those runs before quoting anything, because the ductwork assessment shapes the scope of the job more than the unit selection does.
What a Central AC System Is Made Of
The outdoor unit sits on a concrete pad beside the house and holds the compressor and condenser coil. Inside, the air handler or furnace-mounted evaporator coil sits in a closet, utility room, or attic. Those two pieces are what a homeowner is buying when they commission a new central AC system.
The refrigerant line set runs between the outdoor and indoor units, carrying refrigerant through copper tubing that gets routed along the exterior wall or through the attic. A condensate drain line runs from the indoor coil to a floor drain or exterior exit point, and a thermostat on an interior wall gives the homeowner control over the whole system.
The drawing shows the general layout of a central AC system, and a licensed contractor determines exactly how each piece fits the conditions of your particular 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.
