A contractor sent out to repair a central AC unit in Wilson County has to figure out what actually broke it. 109 severe weather events were recorded in Wilson County, North Carolina between 2015 and 2024. That puts this county in the middle of the national range for severe weather, which means the load is real but not so heavy that it explains every failed component on its own. Compressors, capacitors and contactors do wear under that kind of seasonal stress, but age and how well the system was maintained usually share the blame. A contractor who skips that accounting and blames the weather is leaving the homeowner with a repaired unit and the same underlying problem.
Ductwork and refrigerant lines that have been in place since before many of today's AC manufacturers redesigned their parts catalogs present a specific problem on a repair call: availability. Half the homes in Wilson County, North Carolina were built in 1986 or earlier (2020-2024 ACS 5-year). Equipment that went into houses of that era has since been through multiple refrigerant transitions and parts redesigns, and a contractor opening a failed system here has to establish whether the components it needs are still made, or whether what looks like a straightforward repair has become a sourcing problem. That answer drives the quote more than the diagnosis does.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along a side or rear wall, and it is where the system sheds heat. The indoor air handler or furnace blower lives in a closet, attic, or mechanical room and pushes conditioned air through the house. When either one fails, a contractor starts there.
The evaporator coil mounts directly above the air handler and is where the system pulls heat out of indoor air. The refrigerant line set runs between the two units, and the thermostat on the wall tells the whole system when to run. A fault in any of these can look, at first, like a fault in something else entirely.
The drawing shows the general layout of a central AC system, and a licensed contractor determines what applies to the specific equipment and configuration in your house.

What the repair visit looks like in Wilson 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.

Severe Weather Events in Wilson County
Weather puts a load on cooling equipment that no spec sheet accounts for. How hard a system has to work, and how often it runs at the edge of its capacity, shapes what breaks and when, which makes local weather history a practical part of the repair picture.
