A contractor called out to repair a central AC system in Lee County has to work out what actually wore the equipment down before they can price the job or recommend parts. 71 severe weather events were recorded in Lee County, North Carolina between 2015 and 2024. At that rate, severe weather is an occasional event here rather than a standing operating condition, which means a failed capacitor, a struggling compressor, or a refrigerant leak almost certainly has a different explanation. Deferred maintenance and plain age account for most of what contractors find when they open these systems up.
Ductwork installed for one era of equipment and later adapted for another tends to hide what it is doing wrong until a contractor opens the system and looks. Half the homes in Lee County, North Carolina were built in 1988 or earlier (2020-2024 ACS 5-year). A unit running in a house of that vintage has usually been through at least one round of parts and patches, and the components a technician pulls out on a repair call are often from product lines that manufacturers have discontinued or supply only on long lead times. That changes how a repair gets priced and whether a part can be sourced 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 is released. The indoor air handler or furnace, tucked in a closet, attic, or basement, moves air across the evaporator coil. When cooling stops or weakens, those two assemblies are where a contractor starts.
The evaporator coil lives inside the air handler and is one of the first things a contractor pulls up when the system is icing over or not cooling at all. The refrigerant lines run between the indoor and outdoor units, and the capacitors and contactor inside the condenser cabinet are small electrical parts that fail often enough that a contractor checks them early.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which parts apply to the specific setup in your house.

What Happens When the Contractor Arrives
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.
