Before a contractor can quote a repair on a central AC system here, they have to separate what the climate has done from what time and installation quality have done. 82 severe weather events were recorded in Lincoln County, North Carolina between 2015 and 2024. At that rate, severe weather is a real part of the operating picture, but it is not heavy enough to be the default explanation for a failing compressor or a seized contactor. A contractor working a repair in this county will check refrigerant charge, capacitor condition, and the age of the unit itself, because those factors are more likely to explain what failed than the weather record alone.
Ductwork that has cycled through summer after summer of humidity and heat accumulates problems that show up on a repair call, not on an installation checklist. Half the homes in Lincoln County, North Carolina were built in 1994 or earlier (2020-2024 ACS 5-year). A system failing today may be sitting in duct runs that have separated at joints, grown mold at the plenum, or lost enough insulation to defeat whatever the new refrigerant charge delivers. When a contractor opens the unit and traces the problem back, the repair scope sometimes expands from the component that failed to the path the conditioned air has to travel.
The Parts of a Central AC a Contractor Checks During Repair
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and houses the compressor and condenser coil. These are the pieces a contractor reaches first when a system stops cooling. A failed compressor, a refrigerant leak at the coil, or a seized condenser fan motor are the kinds of faults that show up here.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower. A frozen evaporator coil, a failing blower motor, or a clogged drain line each produce symptoms the rest of the system cannot compensate for. The thermostat and the copper refrigerant lines connecting both cabinets round out what a contractor traces when tracking down a fault.
The drawing shows a typical layout, and a licensed contractor determines which components apply and what work is needed in your specific home.

What happens when the contractor comes out
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.
