A contractor called out to repair a central AC unit in Surry County starts with the components that absorb years of demand: capacitors, contactors, and the compressor itself. 202 severe weather events were recorded in Surry County, North Carolina between 2015 and 2024. At that rate, severe weather is part of the normal background this equipment runs against, and its effects accumulate rather than arriving all at once. A refrigerant leak or a failed contactor in a system this age is worth tracing to what the load has done to it before pricing a straight swap.
Ductwork in houses of this age carries a history that shows up the moment a contractor opens an access panel: sections resealed with materials that have since failed, runs added or closed off as rooms changed use, joints that no longer hold. Half the homes in Surry County, North Carolina were built in 1979 or earlier (2020-2024 ACS 5-year). When a system short-cycles or loses capacity, the opened equipment often tests fine, and the real restriction is in the duct path feeding it. A contractor working a repair here checks static pressure and duct continuity before concluding what the unit itself needs.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house and is usually the starting point when something goes wrong. It holds the compressor, which does the heaviest mechanical work in the system, and the condenser coil, which sheds heat to the outside air. Both are common sources of failure when a system stops cooling.
Inside, the air handler or furnace cabinet holds the evaporator coil and the blower. The evaporator coil pulls heat out of the indoor air, and the blower pushes that air through the house. The refrigerant lines connecting the two units and the thermostat on the wall are also part of what a contractor examines when tracing a problem.
The drawing shows a typical central AC layout, and a licensed contractor determines which components apply to your specific home and situation.

What Repair Work Looks Like in Surry 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.
