A contractor quoting a central AC repair in Catawba County starts by establishing what the system has already been through, because that history shapes which components show stress and which ones failed on their own. 117 severe weather events were recorded in Catawba County, North Carolina between 2015 and 2024. At that rate, severe weather is a standing condition in this area, not an occasional one, and a worn capacitor or a laboring compressor here carries a different story than the same part failing somewhere the seasons run quiet. A contractor who skips that load history and goes straight to the part misses what drove the failure.
Ductwork and refrigerant lines in a house of this vintage were put in for a system that has long since been replaced, meaning a contractor opening the equipment today is working on at least the second or third generation of hardware in that same shell. Half the homes in Catawba County, North Carolina were built in 1985 or earlier (2020-2024 ACS 5-year). When a compressor or control board fails in a system that old, the repair pivots on parts availability. Some components for equipment of that age are still made; others are not, and a contractor has to determine which before a repair is even priceable.
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 is where heat from inside the home gets released to the outside air. The compressor lives inside that cabinet and is the first thing a contractor looks at when the system is running but not cooling.
The air handler or furnace sits indoors, in a closet, attic, or utility room, and it holds the evaporator coil where indoor air gets cooled before moving through the house. The refrigerant lines run between those two units, and the thermostat on the wall controls when the whole system runs. A fault in any of those connections shows up as a cooling problem.
The drawing shows a typical layout, and a licensed contractor determines which components apply and what service is needed in your specific home.

What the repair visit 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.
