The compressor in a central AC unit starts and stops every time the house calls for cooling, and in George County that cycle runs through a long, heat-heavy stretch of the calendar. Homes in George County, MS run cooling about five months a year, from May through September. A contactor that has opened and closed through that many cycles shows it: pitted contacts, sluggish engagement, and eventually a compressor that fails to start. The condenser fan motor carries similar hours. A contractor pulling the panel on a unit here looks at those parts first, because that is where the load lands.
Ductwork in a house this old was sized and routed for whatever system first went into it, not for whatever has been swapped in since. Half the homes in George County, Mississippi were built in 1989 or earlier (2020-2024 ACS 5-year). That means a repair call can turn on whether the flex duct still seals the way it needs to, or whether the air handler compartment the original builder framed will accommodate the part a contractor actually orders. A compressor swap or a coil replacement on a unit running in older construction is straightforward when the surrounding infrastructure holds. When it does not, the scope of the repair changes.
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 gets shed to the outside air. The compressor lives inside that cabinet and is often the first thing a contractor tests when the system stops cooling. A failed compressor, a refrigerant leak at the service valves, or a burned condenser fan motor each shows up here.
Inside the house, the air handler or furnace cabinet holds the evaporator coil, the blower motor, and the filter. The evaporator coil is a common fault point when the system freezes over or loses cooling capacity. The refrigerant lines running between the two units and the thermostat on the wall round out what a contractor works through on a diagnostic call.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply and what condition they are in for your specific home.
