A central AC system in Buncombe County has been running against something most homeowners do not factor into a repair call: a genuine, recurring pattern of severe weather. 88 severe weather events were recorded in Buncombe County, North Carolina between 2015 and 2024. At that rate, the stress on cooling components adds up over the life of a system, and a contractor working a repair here checks for wear patterns consistent with repeated load spikes before concluding that age or neglect is the whole story. A capacitor or compressor that looks simply old may have been pushed harder than the install year alone would suggest.
Ductwork and electrical wiring put in for an older house do not get replaced when a newer AC system goes in. Half the homes in Buncombe County, North Carolina were built in 1991 or earlier (2020-2024 ACS 5-year). A contractor who opens a failed central AC unit here is working with components that have been pulling against infrastructure laid down before them, and the wear pattern inside the unit reflects that history. Corroded contacts, stressed capacitors, a compressor laboring against static pressure it was not spec'd for: these are the conditions that set the repair bill, and they show up only once the system is open.
The Parts of a Central AC a Contractor Checks During Repair
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and it sheds the heat pulled from your home. Inside, the air handler or furnace cabinet holds the evaporator coil, which is where the refrigerant does its work. When either of these is the problem, the symptoms show up fast: warm air, ice on the coil, or the system short-cycling.
Refrigerant lines run between the two units, and the system also depends on a set of smaller components: the capacitor and contactor in the outdoor cabinet, the blower motor in the air handler, and the thermostat on the wall. A contractor checks these alongside the main equipment because a failed capacitor or a weak blower motor can produce the same complaints as a refrigerant problem.
The drawing shows a typical central AC layout, and a licensed contractor determines which components apply and what condition they are in for your specific house.

What HVAC Repair Looks Like in Buncombe 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.
