A contractor quoting a central AC repair in Clark County has to sort out what the system has already been through before settling on a cause. 132 severe weather events were recorded in Clark County, Indiana between 2015 and 2024. At that rate, stress on the condenser coil and the capacitor is a real variable, and a contractor checks both before writing the failure off as ordinary wear. If those components show stress-related degradation rather than simple age, the repair scope shifts and so does what gets replaced.
Ductwork in a house this old was sized and routed for whatever system was original to it, and the AC running in it now is almost certainly not that system. Half the homes in Clark County, Indiana were built in 1982 or earlier (2020-2024 ACS 5-year). What that means for a repair is specific: once a contractor opens the unit, the question is whether the parts it calls for are still in production or have to be sourced as old stock. A failed capacitor or contactor is rarely the problem. A compressor or evaporator coil on a system that predates current refrigerant standards can push a repair into territory where the part exists but the lead time or the cost changes the whole job.
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 holds the compressor and the condenser coil. The compressor is where most repair calls begin. When the system runs but cools poorly, or makes a hard start noise, or trips the breaker, the condenser is where a contractor looks first.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower. The evaporator coil is a common source of refrigerant leaks and ice buildup. The blower moves conditioned air into the duct system, and the contractor will also check the expansion valve and the refrigerant lines that run between the two cabinets.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific system and what work each one needs.

What HVAC Repair Looks Like in Clark 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.
Severe Weather Events in Clark County
Every storm that moves through Clark County puts real hours on the cooling equipment that runs before, during, and after it. That kind of accumulated stress is why weather history belongs alongside any conversation about AC repair.
