A contractor quoting central AC repair in Ohio County starts with the unit itself: how old the components are, whether the system was installed correctly, and how consistently it has been serviced. 47 severe weather events were recorded in Ohio County, Indiana between 2015 and 2024. At that rate, severe weather is an occasional event here, not a constant operating pressure, so a compressor failure or a refrigerant problem points back to age and maintenance before it points anywhere else. A contractor who skips that internal assessment and attributes the failure to weather is leaving the actual cause on the table.
Half the homes in Ohio County, Indiana were built in 1978 or earlier (2020-2024 ACS 5-year). A system running in a house that old has likely been through at least one equipment swap, and what a contractor finds once the unit is open reflects whatever was available and affordable at the time of that swap. The meaningful question on a repair call here is whether the parts the system actually takes are still manufactured. If they are not, a repair that looks straightforward from the outside stalls at sourcing.
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 condenser coil. These are where a contractor starts. A failed compressor, a refrigerant leak at the coil, or a burned capacitor will each stop the system in its own way, and the symptoms often point to one of these before anything else.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower motor. The evaporator coil sits above the furnace in a closet or utility space and is a common source of ice buildup and refrigerant problems. The blower motor moves conditioned air through the house, and when it runs weak or not at all, the contractor checks it alongside the coil.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply to your specific house and equipment.

What HVAC Repair Looks Like in Ohio 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 Ohio County
Hard weather puts real hours on cooling equipment. A system that cycles hard through storm season runs differently than one that sits in mild air, and that gap shows up in how often repairs are needed and how soon parts wear.
