A contractor called out for a central AC repair in Yancey County has to work out what actually wore the system down, and severe weather belongs low on that list. 35 severe weather events were recorded in Yancey County, North Carolina between 2015 and 2024. At that rate, most systems here go long stretches without being pushed hard by outside conditions. Refrigerant lines degrade, capacitors fail, coils corrode from age and neglect. A contractor will look at how the system has been maintained and how old its components are before attributing anything to the weather.
Ductwork in housing this old has seen more than one system come and go, which means the refrigerant type, the electrical configuration, and the replacement parts a contractor needs have all shifted at least once since the house was built. Half the homes in Yancey County, North Carolina were built in 1988 or earlier (2020-2024 ACS 5-year). When a central AC unit is opened for repair, the question is whether the components it takes are still in production or whether a contractor is sourcing from a shrinking pool of compatible parts. That answer drives both what the repair costs and whether a repair makes sense at all.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and it is where heat gets released. The indoor air handler or furnace sits inside, often in a closet, attic, or utility room, and moves conditioned air through the house. When one of those two units is the problem, the repair starts there.
The refrigerant line set runs between the two units, and a contractor checks it for leaks or pressure loss when the system is cooling poorly. The evaporator coil sits inside the air handler and is a frequent source of trouble, whether from ice buildup, dirt, or refrigerant issues. The thermostat, mounted on an interior wall, is also an early stop because a wiring fault or failed sensor there can mimic a much larger mechanical problem.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which parts need attention in your particular house.

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.
