Takes about a minute. No obligation.
A compressor starting and stopping through a full cooling season accumulates wear on its contactor, its capacitor, and the motor windings in ways that a short season would not. Homes in Hampton County, SC run cooling about five months a year, from May through September. By the time a system shows a fault, the contactor has likely cycled thousands of times and the capacitor has been holding starts under sustained summer heat. A contractor diagnosing a failed central AC unit here looks at those components first, because the load the season places on them is long enough that they give out before the refrigerant circuit or the ductwork does.
Ductwork and wiring tend to outlast the equipment they were originally built around, but the AC unit itself cycles through sooner. Half the homes in Hampton County, South Carolina were built in 1984 or earlier (2020-2024 ACS 5-year). What that means for repair work is specific: once a contractor opens a system, the question is whether the failed component is still manufactured. Discontinued parts send a job in a different direction entirely, toward adapted substitutes or a full replacement conversation. That is the variable this housing stock makes live on nearly every repair call.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad at grade, and it holds the compressor and the condenser coil. These are the parts a contractor reaches first when a system stops cooling. The compressor is the most likely source of a hard failure, while the condenser coil and its fan motor account for a large share of reduced performance calls.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower motor. The evaporator coil sits directly above the heat exchanger or in its own plenum, and it is where refrigerant problems, drain issues, and airflow restrictions most often show up. A contractor also checks the refrigerant lines that run between the two units and the service valves at each end.
The drawing shows a typical central AC layout, and a licensed contractor determines which components apply and need attention in your specific home.

What HVAC Repair Looks Like in Hampton 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.
