A contractor quoting a central AC repair in Fayette County starts with the system itself: how old the equipment is, how well it was installed, and whether it has been serviced. 43 severe weather events were recorded in Fayette County, Indiana between 2015 and 2024. At that rate, severe weather is something equipment here encounters now and then, not a relentless load that grinds components down season after season. A refrigerant leak or a failing capacitor almost always traces back to age or a maintenance gap, and a contractor who blames storm exposure without checking those first is skipping the work.
Ductwork in housing this old has had time to pull apart at joints, accumulate blockages, and lose whatever original sealing it had. Half the homes in Fayette County, Indiana were built in 1962 or earlier (2020-2024 ACS 5-year). When a contractor pulls a panel and the refrigerant charge looks right but the system still underperforms, the ducts are where they look next. Gaps and collapsed sections raise static pressure, which strains the air handler and shortens the run time of parts that could otherwise last. A repair call that comes in about cooling becomes a duct inspection before it becomes anything else.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along a wall, and it houses the compressor and condenser coil. These are the parts a contractor reaches first when the system stops cooling. A failed compressor, a refrigerant leak at the coil, or a seized condenser fan motor will each show up here.
Inside, the air handler or furnace cabinet holds the evaporator coil and the blower that moves air across it. The refrigerant line set runs between the two cabinets, and the expansion valve sits where that line meets the indoor coil. A frozen evaporator coil, a blocked blower wheel, or a leak along the line set are all common points of failure a contractor traces back through this path.
The drawing shows a typical layout, and a licensed contractor assesses which components apply and what condition they are in for your specific house.

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.
