A contractor quoting a central AC installation in Logan County has to size the equipment for a compressor that will be starting and stopping through a real summer workload, not a marginal one. Homes in Logan County, AR run cooling about five months a year, from May through September. The contactor, the condenser fan motor, and the compressor itself absorb that load every year, and a system that was undersized or charged incorrectly at install runs harder to keep up. That extra strain shows in the compressor long before it shows anywhere else. Getting the load calculation and the refrigerant charge right at installation is what separates a system that holds up from one that does not.
Ductwork laid down for one generation of equipment does not automatically carry the next. Half the homes in Logan County, Arkansas were built in 1979 or earlier (2020-2024 ACS 5-year). That gap between what the house was built around and what a contractor is now asked to install is where a central AC job either holds its budget or blows it. If the existing ducts cannot handle the airflow a new system requires, a contractor has to resize them before the new unit goes in. The electrical service runs into the same question: older panels were not sized for modern loads, and a contractor pricing an installation has to look at the panel before the quote means anything.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a pad beside the house and holds the compressor and condenser coil, the hardware that does the heaviest work in the system. Inside, the air handler or furnace-mounted evaporator coil lives in a utility space, basement, or closet, where it connects to the home's existing ductwork. Together these two pieces are what a homeowner is buying.
A refrigerant line set runs between the indoor and outdoor units, and a condensate drain line carries moisture away from the evaporator coil to a floor drain or outside. The thermostat goes on a main living-area wall and gives the homeowner control over the whole system.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this 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.

Severe Weather History in Logan County
Extreme heat, cold snaps, and storm pressure cycles all put hours on HVAC equipment faster than mild weather does. What the climate does in Logan County shapes how hard a new central AC system has to work and how it should be sized and installed.
