Takes about a minute. No obligation.
A contractor diagnosing a central AC system here has to settle one thing before pricing any repair: whether the compressor, capacitor, or contactor failed from accumulated load or from something unrelated to the weather this area sees. 161 severe weather events were recorded in Effingham County, Georgia between 2015 and 2024. At that rate, severe weather is a standing condition of operating here, not an occasional variable, and the components that carry electrical and thermal stress show it. A contractor who skips that check quotes the wrong fix.
Half the homes in Effingham County, Georgia were built in 2001 or earlier (2020-2024 ACS 5-year). For a house built around that time, the framing, ductwork, and electrical were put in for equipment of the same era, so the building itself rarely explains why a system is failing. What a contractor finds once the unit is open is where the diagnosis lives: the condition of the compressor, whether refrigerant has been leaking, what the capacitors or contactors show under inspection. A house that young does not steer a repair quote the way an older one can. The equipment does.
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 houses the compressor and condenser coil. These are where the system does its hardest work, and a contractor will look here early. A failed compressor, a refrigerant leak at the coil, or a seized fan motor all show up as the same symptom to a homeowner: the system runs but the house stays warm.
Inside the house, the air handler holds the evaporator coil and the blower that pulls air across it. It sits in a closet, attic, or utility room and feeds the duct system from there. The metering device and refrigerant lines connect the two units, and a contractor checks both sides of that circuit when tracking down a pressure or airflow problem.
The drawing shows a typical layout, and a licensed contractor determines what applies to this particular house and system.

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 Effingham County
Georgia's coastal plain climate puts real stress on air conditioning equipment, and Effingham County gets its share of the weather that drives that stress. How hard a system has worked through storms and heat loads shapes what a repair technician finds when one finally fails.
