Takes about a minute. No obligation.
The compressor in a Kershaw County home starts and stops hundreds of times each cooling season, and that cycling is where the mechanical load concentrates. Homes in Kershaw County, SC run cooling about five months a year, from May through September. A contractor diagnosing a repair here looks at the compressor, the contactor, and the condenser fan before anything else, because those are the parts that absorbed the work. Refrigerant charge, capacitor condition, and contactor pitting are the places wear shows up in a system that has been running hard season after season.
Half the homes in Kershaw County, South Carolina were built in 1993 or earlier (2020-2024 ACS 5-year). Central AC systems running in houses that old have passed through multiple service cycles, and what a contractor finds when the unit is opened is often a compressor or refrigerant type that parts suppliers no longer stock as a matter of course. That changes the repair from a straightforward fix into a sourcing question. If the part exists, the job proceeds; if the line has been discontinued, the contractor has to say so before any other decision gets made.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad alongside the foundation, and it holds the compressor and condenser coil. These are where a contractor starts when the system stops cooling. A failed compressor, a refrigerant leak at the coil, or a seized fan motor in that cabinet are among the first things they rule out.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower motor. The evaporator coil is a common fault point when airflow feels weak or the system ices over. A refrigerant line set connects the two cabinets, and the thermostat on the wall tells the whole system when to run, so both get checked when the symptom points that way.
The drawing shows a general layout of these components, and a licensed contractor determines what applies to your specific house and system.

What the Repair Work 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.
