A contractor quoting a repair on a central AC system here has to work out what the equipment has already been through before they can say which component failed and why. 76 severe weather events were recorded in Tattnall County, Georgia between 2015 and 2024. At that rate, severe weather is a recurring part of normal operating life for any system in this county, not an occasional exception, and it leaves a record in the hardware. Capacitors, contactors, and the compressor itself carry that load over years. A failure that looks straightforward on the outside often opens up into wear that accumulated long before anything stopped working.
Ductwork in a house built for an earlier era of cooling gets adapted over time, and the equipment that runs through it gets replaced more than once. Half the homes in Tattnall County, Georgia were built in 1987 or earlier (2020-2024 ACS 5-year). What a contractor finds once a central AC unit is opened in stock like this is rarely a straightforward catalog match: the system running today may be a third-generation replacement, drawing parts from a lineage the original house never anticipated. If those parts are scarce or discontinued, the repair scope shifts before the quote does.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits on a pad outside the house and holds the compressor and condenser coil, which are the pieces that shed heat from the refrigerant. When the system runs but cools poorly, or makes noise, or trips the breaker, the compressor and that coil are where a contractor starts.
Inside the house, the air handler holds the evaporator coil and the blower. The evaporator coil pulls heat out of indoor air, and the blower pushes that air through the house. The expansion valve, refrigerant lines, and the thermostat round out what a contractor traces when the outdoor unit checks out but something is still wrong.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply to your particular house.

What HVAC Repair Looks Like in Tattnall 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.
