A Central AC unit in Cuyahoga County has not been sitting out mild summers. 283 severe weather events were recorded in Cuyahoga County, Ohio between 2015 and 2024. At that rate, severe weather is a standing feature of what equipment here runs against, season after season, and the compressor and electrical components carry the weight of it. A contractor quoting a repair in this county expects to find wear that reflects a sustained load, not a single bad event, and that shapes which parts get inspected first and what gets replaced.
Ductwork in a house from this era gets repaired, relined, and rerouted over decades, and the central AC system running through it carries its own accumulation of prior fixes. Half the homes in Cuyahoga County, Ohio were built in 1957 or earlier (2020-2024 ACS 5-year). That history means a contractor opening a unit here finds components sourced across different service generations, and the part that failed may belong to a production run that ended years ago. Availability, not labor, is often what sets the final scope of a repair job.
The Parts of a Central AC a Contractor Checks During Repair
The outdoor condenser unit sits beside the house and holds the compressor and condenser coil, both of which are common starting points when a system stops cooling. The indoor air handler or furnace-mounted evaporator coil sits inside, usually in a basement or utility closet, and is where refrigerant absorbs heat from the air moving through your home.
The copper refrigerant lines run between those two units, and a fault anywhere along them shows up as poor cooling or ice buildup on the coil. The expansion valve and the capacitors that start and run the compressor and fan motors are smaller components that a contractor will test early, since they fail in ways that mimic larger problems.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply to your specific house and situation.

What the Repair Visit Looks Like
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.
What Cuyahoga County and Ohio Require for This Work
An Ohio home construction services contract must include a copy of the supplier's certificate of insurance showing general liability coverage of not less than two hundred fifty thousand dollars.
In Ohio a home construction service means the construction of a residential building, including the repair, improvement, remodel or renovation of an existing structure, and does not include construction on a structure containing four or more dwelling units except for work on an individual dwelling unit within it.
A home construction service supplier in Ohio is defined as a person who contracts with an owner to provide home construction services for compensation and who maintains a general liability insurance policy of not less than two hundred fifty thousand dollars.
The Ohio construction industry licensing board issues state licenses to individuals as heating, ventilating and air conditioning contractors, refrigeration contractors, electrical contractors, plumbing contractors and hydronics contractors.
An Ohio board of county commissioners may accept a valid and unexpired Chapter 4740 license held by a heating, ventilating and air conditioning contractor toward its own licensing requirements for work on one-, two-, or three-family dwelling houses.
An Ohio board of county commissioners may adopt rules licensing heating, ventilating and air conditioning contractors who are not required to hold a state license under Chapter 4740.
In Ohio municipal law a specialty contractor includes heating, ventilating and air conditioning contractors, refrigeration contractors, electrical contractors, plumbing contractors and hydronics contractors.

Violating Ohio's contractor licensing prohibition is a minor misdemeanor on a first violation and a misdemeanor of the fourth degree on subsequent violations.
Under Ohio law no person may act as or claim to be a type of contractor that Chapter 4740 licenses unless that person holds a license issued under that chapter.

Severe Weather Events in Cuyahoga County
Weather puts real load on cooling equipment, and that load accumulates over time. How hard a system has worked shapes what kind of repair it needs and how soon.
