A contractor diagnosing a failed central AC unit in Morrow County has to decide what actually wore the system down. 43 severe weather events were recorded in Morrow County, Ohio between 2015 and 2024. At that rate, severe weather is something equipment here encounters periodically, not a relentless seasonal load. A compressor that quits in a county with that kind of record is more likely showing the effects of deferred maintenance or original installation quality than storm-related stress. That distinction sends a contractor toward the refrigerant circuit, the electrical contacts, and the service history before anything else.
Ductwork and refrigerant lines in a house this age have usually outlasted more than one cooling system, and the unit running today is often a retrofit on infrastructure that was never matched to it at the factory. Half the homes in Morrow County, Ohio were built in 1980 or earlier (2020-2024 ACS 5-year). What that means for a repair is that when a contractor pulls a failed component, the question is whether a replacement part is still in production for a system that was itself installed years after the house was finished. If the part is discontinued, the scope of the job changes before the diagnostic sheet is done.
The Parts of a Central AC a Contractor Checks During Repair
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and it holds the compressor and condenser coil. These are the parts a contractor reaches first when something stops working, because the compressor drives the whole system and the condenser coil sheds heat to the outside air. A fault in either one shuts down cooling fast.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower. The evaporator coil pulls heat out of the indoor air, and the blower pushes that air through the house. The refrigerant line set connects the two cabinets, and the thermostat tells the whole system when to run, making it another piece a contractor checks when the complaint is short-cycling or no response.
The drawing shows the typical layout of these components, and a licensed contractor determines what applies to this particular house and system.

What HVAC Repair Looks Like in Morrow 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.
