Takes about a minute. No obligation.
A contractor called out for a central AC repair in Clayton County has to work out how hard the system has been running before they can say with confidence what failed. 51 severe weather events were recorded in Clayton County, Georgia between 2015 and 2024. At that rate, compressors and condenser coils in this county carry a real cumulative load, and a part that looks like it failed early may simply have been worked hard from the start. A contractor checks refrigerant pressure, coil condition, and electrical connections with that history in mind, because the repair scope follows from what the system has actually been asked to do.
Ductwork and wiring aside, what a repair job in this county actually hinges on is parts availability. Half the homes in Clayton County, Georgia were built in 1989 or earlier (2020-2024 ACS 5-year). Equipment cycles through a house over decades, and by the time a system is old enough to fail in a meaningful way, the components it takes are sometimes discontinued or available only through secondary suppliers at longer lead times and higher prices. A contractor opening a failed unit here checks whether the repair is even possible before pricing it.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit, which sits on a concrete pad outside the house, is where most repairs begin. It houses the compressor and the condenser coil, and when either one fails, the system stops shedding heat and the house stops cooling. The air handler inside, usually in a closet, attic, or utility room, holds the blower and the evaporator coil, and a fault there shows up as weak airflow or air that never gets cold.
The refrigerant lines run between those two units, and a leak anywhere along them starves the whole system. The thermostat on the wall and the capacitors and contactors inside the condenser cabinet are smaller parts, but they are the first things a contractor checks because they fail more often than the major components and are straightforward to test and swap.
The drawing shows a typical layout, and a licensed contractor determines what applies to this specific house and system.

What HVAC Repair Looks Like in Clayton County
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.
