A contractor quoting a central AC repair in Posey County has to separate what the weather has done to a system from what time and upkeep have done. 92 severe weather events were recorded in Posey County, Indiana between 2015 and 2024. At that rate, severe weather is a real part of operating life here, enough that a contractor checks wear on the components that carry the heaviest load during high-demand runs. But the record sits near the middle nationally, so a failed capacitor or a compressor that has given out is more likely telling a story about age and service history than about storm exposure. That is what shapes the diagnosis and, often, the repair bill.
Ductwork in a house this old has been patched, re-routed, and lived with through multiple equipment cycles, and what a contractor finds once the unit is open reflects that full history. Half the homes in Posey County, Indiana were built in 1976 or earlier (2020-2024 ACS 5-year). A system running in stock of this age is seldom the original install, which means the refrigerant type, the coil configuration, and the replacement parts a repair requires may belong to a line that a manufacturer has since discontinued. That is the variable that shapes the repair scope here: not what failed, but whether what failed can still be sourced.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and it is where heat gets released to the outside air. The compressor lives inside that cabinet and is the piece contractors look at early when a system runs but does not cool. A failed compressor or a refrigerant leak at the condenser often explains the most common cooling complaints.
Inside the house, the air handler or furnace cabinet holds the evaporator coil, which is where the cold side of the system does its work. A frozen coil, a clogged drain line, or a failing blower motor inside that cabinet are each capable of stopping airflow or causing the system to shut itself down. The thermostat on the wall is the last piece a contractor checks against, since a wiring fault or a failed sensor there can mimic a much larger problem.
The drawing shows a typical central AC layout, and a licensed contractor determines which components and conditions apply to your specific home.

What Happens When a Contractor Comes Out
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.
