A contractor called out to repair a central AC system in Cherokee County has to work out what actually wore the equipment down. 68 severe weather events were recorded in Cherokee County, North Carolina between 2015 and 2024. At that rate, severe weather is an occasional event here, and a system in trouble is almost certainly in trouble for other reasons. Capacitors fail from age. Refrigerant lines develop leaks from years of vibration and poor original installation. The load this climate puts on a system is real but not the kind that explains most of what a contractor finds opened up on a repair call.
Ductwork and refrigerant lines sized for equipment that no longer exists still run through a large share of homes here. Half the homes in Cherokee County, North Carolina were built in 1994 or earlier (2020-2024 ACS 5-year). When a system in a house that age needs a repair, what the opened unit reveals is often a configuration that ran on components now discontinued or available only through specialty suppliers, and that supply question shapes the scope of the job before labor or time enter the picture. A contractor pulling a failed part number and finding it orphaned has to bring that answer back to the homeowner 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 at ground level, and it carries the compressor and condenser coil. These are the pieces a contractor reaches first when a system stops cooling. A failed compressor or a damaged coil is often where the diagnosis lands.
Inside the house, the air handler holds the evaporator coil and the blower that moves air across it. The refrigerant lines run between the two units, and the thermostat on the wall tells the whole system when to run. A fault in any of these can stop cooling, change airflow, or cause the system to run without doing useful work.
The drawing shows a typical layout, and a licensed contractor will determine which components apply to your specific system and what repair each one needs.

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.
