Sizing is the first decision a contractor has to settle before anything else on a central AC install makes sense. Homes in Monroe County, AR run cooling about five months a year, from May through September. A compressor cycling through that full run of heat accumulates starts and stops on the contactor, hours on the condenser fan, and sustained load on the refrigerant circuit. An undersized system runs longer each cycle trying to hold the setpoint, and the parts that wear fastest are exactly the ones already under that seasonal pressure. A contractor doing the load calculation here accounts for the house envelope, the ductwork already in place, and the equipment capacity needed to reach the end of September without the compressor being pushed past its design limits.
Ductwork laid out for older equipment carries different static pressure, different trunk sizes, and often different routing than what a modern central AC installation calls for. Half the homes in Monroe County, Arkansas were built in 1976 or earlier (2020-2024 ACS 5-year). A contractor quoting a new system has to trace what is actually in the walls and attic before the equipment selection means anything, because a unit that is correctly sized for the house can still underperform if the duct system restricts it. The electrical service gets the same look: load requirements for current-generation AC units do not always match what the existing panel was wired to handle.
What a Central AC System Includes
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and holds the compressor and condenser coil. Inside, the air handler or furnace-mounted evaporator coil sits in a utility space, basement, or closet and is where the system meets the air that moves through your home.
The refrigerant line set runs between those two units, connecting the indoor and outdoor sides through a small penetration in the wall. A thermostat mounts on an interior wall and gives you control over when the system runs.
The drawing here shows the general layout of a central AC system, 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.
Licensing and Legal Requirements in Monroe County, Arkansas
An Arkansas HVACR licence is good across the state: no city or county may require its own licence to do HVACR work, though local permits and inspections still apply.
Arkansas requires an HVACR licence or registration: it is unlawful to do HVACR work without the appropriate one unless the chapter exempts you.
Severe Weather Events in Monroe County
Local weather puts a measurable load on cooling equipment, and that load shapes what a properly sized, properly installed system needs to handle. Central AC in Monroe County is a local decision partly because the weather here is a local fact.
