Takes about a minute. No obligation.
The compressor in a central AC unit starts and stops repeatedly across a long cooling season, and that cycling is where the wear lands. Homes in Oconee County, SC run cooling about four months a year, from June through September. Contactors burn, capacitors weaken, and condenser fan motors collect the load of those repeated starts. A contractor diagnosing a fault here pulls the electrical components first, because that is where the hours show up. Refrigerant loss and coil fouling follow, but the parts that cycle with every call for cooling are the ones that give out.
Ductwork sized and sealed for equipment that no longer exists is what a contractor opens up to in a large share of Oconee County houses. Half the homes in Oconee County, South Carolina were built in 1990 or earlier (2020-2024 ACS 5-year). That matters for repair work specifically because the components a technician pulls out of a unit running in stock like this are often from product lines that manufacturers have since discontinued, which changes the repair from a parts swap into a sourcing problem. Whether a replacement part still exists, and in what form, is what determines the actual scope and direction of the job.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along an exterior wall, and it is where heat pulled from inside the home gets released. The indoor air handler or furnace cabinet lives in a utility closet, attic, or basement and moves conditioned air through the house. When the system stops cooling or runs but does nothing useful, one of these two units is where a contractor starts.
The refrigerant lines run between those two units and carry the working fluid that makes the whole process possible. The expansion valve, the metering device that sits where the refrigerant enters the indoor side, and the capacitors and contactors inside the outdoor unit are the smaller components a contractor opens panels to reach. A failed capacitor or a blocked metering device can stop a system just as completely as a failed compressor.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply and what they find in your specific home.

What HVAC Repair Looks Like in Oconee 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 Oconee County
Storm activity puts real strain on cooling equipment: power surges, sudden shutdowns, and prolonged heavy loads all shorten the life of components. How hard weather hits here shapes how hard the equipment works, which makes repair demand in Oconee County a local story, not a general one.
