The compressor and the condenser fan carry the full weight of a Lawrence County summer. Homes in Lawrence County, AR run cooling about four months a year, from June through September. By late September, those components have been starting and stopping through weeks of sustained heat, and that cycling is where wear actually accumulates. A contactor burned from repeated starts, a capacitor that can no longer hold a charge, a condenser coil running dirty from a full season of outdoor air: these are what a contractor finds first when the system finally quits.
Ductwork in a house this old has typically been worked on by more than one contractor over the decades, and what it actually contains behind the registers is rarely what any one of them specified. Half the homes in Lawrence County, Arkansas were built in 1978 or earlier (2020-2024 ACS 5-year). That history matters at the repair stage: when a technician opens a unit, the refrigerant type, the capacitor spec, and the contactor configuration may belong to a system installed well after the house was framed, and sourcing parts for mid-life equipment in a county where much of the stock predates it means the supply chain is thinner than the unit's age alone would suggest.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along a wall, and it holds the compressor and condenser coil. These are the pieces a contractor reaches first when the system stops cooling, because the compressor is what drives the whole refrigeration cycle and the condenser coil is where heat gets shed to the outside air.
Inside the house, the air handler holds the evaporator coil and the blower. The air handler sits in a utility closet, basement, or attic and pushes conditioned air into the duct system. A refrigerant line set runs between the two units, and a thermostat on the wall controls when the system runs.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific house and equipment.

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.
