Takes about a minute. No obligation.
The compressor in a central AC unit starts and stops repeatedly across a long summer, and each cycle stresses the contactor, the capacitor, and the refrigerant seals. Homes in Newberry County, SC run cooling about five months a year, from May through September. By the time a system shows a fault, the compressor has already logged the kind of accumulated load that tells a contractor where to look: worn contactors, a failing capacitor, or seals that have been working hard since May. A unit that was undersized at installation has no slow season to recover in, and a contractor quoting a repair here prices that history into the scope before anything else.
Ductwork in a house carries wear from every system that has ever run through it, and in much of Newberry County that history is long. Half the homes in Newberry County, South Carolina were built in 1981 or earlier (2020-2024 ACS 5-year). When a central AC system fails in stock like this, what the opened unit reveals often includes parts that manufacturers have discontinued or supply on limited runs. A contractor has to confirm availability before quoting a repair, because a part that exists in a catalog and a part that ships in a reasonable window are two different things.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house and holds the compressor and condenser coil, the two pieces a contractor reaches for first when a system stops cooling. The compressor is the heart of the refrigerant circuit, and a failed one is often what turns a repair call into a bigger job. The condenser coil sheds heat to the outside air, and a damaged or dirty coil shows up fast in how the system performs.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower, which together pull warm air across refrigerant and push conditioned air into the ducts. The refrigerant lines connecting the two units and the expansion valve that meters refrigerant flow are also points a contractor inspects when the coil and compressor check out fine. The thermostat, mounted on a wall, controls the whole sequence and is a frequent first stop before any other component gets opened up.
The drawing shows a typical layout, and a licensed contractor determines which components and access points apply to your specific house.

What HVAC Repair Looks Like in Newberry 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.
