The compressor on a central AC unit in this area earns its wear honestly. Homes in Horry County, SC run cooling about five months a year, from May through September. Every start and stop of that compressor loads the contactor, stresses the capacitor, and builds heat in the windings. By the time a homeowner calls for a repair, those components have absorbed a full season of work, and a contractor checking a struggling system here goes straight to them rather than to the refrigerant charge or the filter.
Ductwork in a house old enough to have been sealed and insulated under earlier standards puts a different kind of pressure on repair work than most homeowners expect. Half the homes in Horry County, South Carolina were built in 1999 or earlier (2020-2024 ACS 5-year). A unit that short-cycles, ices up, or loses capacity may have a real component fault, but a contractor who opens the equipment and stops there is only reading half the job. The ductwork's condition shapes how hard the system has been working, and that load history is what determines whether a replaced part holds or fails again in the same season.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and it holds the compressor and condenser coil. These are the pieces a contractor goes to first when a system is blowing warm air or not running at all. A failed compressor or a coil clogged with debris are among the most common reasons a central AC stops doing its job.
Inside the house, the air handler or furnace holds the evaporator coil and the blower. The evaporator coil is a frequent source of trouble: it can freeze over or develop a refrigerant leak, both of which show up as weak cooling or ice on the unit. The blower moves conditioned air through the house, and a failing motor there will cut airflow even when the rest of the system is working.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components are actually involved in your specific situation.

What the repair visit looks like
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 Horry County
Storm activity puts a measurable load on cooling equipment. Capacitors, contactors, and refrigerant lines all take the hit when power surges and heat spikes follow rough weather, which is why local storm history is part of understanding what drives repair demand in this area.
