A contractor called out to repair a central AC unit in Stark County has to establish what the system has been running against. 131 severe weather events were recorded in Stark County, Ohio between 2015 and 2024. At that rate, severe weather is part of the normal operating life of equipment here, not an occasional outlier, and it shows up in specific ways: contactors pit, capacitors weaken, and refrigerant lines take stress that builds over seasons. A repair quote that skips that history and prices only the obvious failed part can miss what drove the failure.
Ductwork and refrigerant lines in this county's older homes have outlasted the original equipment they served, and the central AC systems running in them now are rarely the first replacements. Half the homes in Stark County, Ohio were built in 1966 or earlier (2020-2024 ACS 5-year). A contractor opening a unit here has to confirm which generation of parts the system actually takes before a repair scope is real, because equipment swapped in over the decades does not follow a tidy progression, and a part that looks standard may not be. What the opened system requires is the repair's deciding variable.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house and holds the compressor and condenser coil, which are the parts under the most mechanical stress. When the system runs but the house stays warm, a contractor looks here first. The compressor in particular is a common point of failure.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower. The evaporator coil pulls heat out of your indoor air, and a refrigerant line set connects it to the outdoor unit. The blower pushes conditioned air through your vents, and a clogged or iced coil, a worn blower motor, or a refrigerant leak in the line set can each stop the system from doing its job.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific setup.

What HVAC Repair Looks Like in Stark 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.
