A contractor quoting a repair on central AC in Warrick County has to account for what the equipment has already been through before they can say what failed and why. 108 severe weather events were recorded in Warrick County, Indiana between 2015 and 2024. At that rate, severe weather is a standing condition for every system in this county, and parts that manage heat exchange and electrical load under stress tend to show that history first. A refrigerant-side failure or a capacitor that has given out is worth looking at differently here than it would be somewhere the equipment runs mostly calm seasons.
Half the homes in Warrick County, Indiana were built in 1986 or earlier (2020-2024 ACS 5-year). The systems running in those houses now are not the original equipment. Central AC has been replaced and updated in cycles since, which means a technician opening a failed unit today is often working on a platform that sits somewhere in the middle of that history, with parts that may have been discontinued before the current owner moved in. That is where repair calls here tend to stall: not at the refrigerant line or the thermostat, but at the parts lookup for a system whose manufacturer has moved on.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad alongside the foundation, and it is where the system sheds the heat it has pulled from inside. When a central AC stops cooling, a contractor starts here. The condenser fan, the refrigerant coils wrapped around the unit, and the compressor at its core are all common points of failure.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower that moves air across it. The refrigerant lines connecting the two units run between them, and the thermostat on the wall tells the whole system when to run. A fault in any of these can produce the same symptom at the vent.
The drawing shows a representative layout of a central AC system, and a licensed contractor determines which components and conditions apply to your specific home.

What Happens Once 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.
Severe Weather Events in Warrick County
Extreme weather puts real stress on cooling equipment, and that stress compounds over time. Repair needs in Warrick County track closely with what the local climate demands from systems that run hard to hold a steady indoor temperature.
