A central AC failure in Hocking County is more likely a story about years of deferred maintenance or a worn compressor than about what the sky has thrown at it. 78 severe weather events were recorded in Hocking County, Ohio between 2015 and 2024. At that rate, severe weather is an occasional event here, and a contractor working through a repair quote will not find much evidence that storm load has driven the failure. What they will find are the usual culprits: refrigerant that has been low for seasons, a capacitor that finally gave out, or coils that have not been cleaned in years. The weather is not what needs explaining.
Ductwork and wiring in a house this old were already in place before most of the equipment now sitting in it was ever manufactured. Half the homes in Hocking County, Ohio were built in 1981 or earlier (2020-2024 ACS 5-year). When a central AC unit fails here and a contractor opens it up, the question that follows is whether the parts it takes are still made and still moving through supply chains. Compressor replacements, control boards, and refrigerant fittings for systems in housing this vintage can sit outside what distributors carry on the shelf, which changes how long the repair takes and what the contractor has to source.
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 heat pulled from your home gets released. The indoor air handler or furnace-mounted evaporator coil sits inside, most often in a basement or utility closet, and it is the side that absorbs heat from indoor air. Both are primary targets when a system blows warm air or stops running.
The refrigerant lines are copper tubes that run between the indoor and outdoor units, carrying the refrigerant that moves heat between the two sides. The thermostat on an interior wall controls the whole sequence, and a failed or miscalibrated thermostat can look exactly like a compressor or coil problem until a contractor rules it out.
The drawing shows a typical central AC layout, and a licensed contractor determines which components are relevant to your specific home and system.

What Happens When the 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.
