A central AC unit that stops cooling in Kent County is almost always failing for reasons a contractor can point to on the equipment itself. 90 severe weather events were recorded in Kent County, Michigan between 2015 and 2024. At that rate, severe weather is part of life here but stays occasional enough that it rarely accounts for a compressor giving out or a coil failing. A contractor working a repair will look at how old the system is, whether refrigerant has been leaking slowly, and how consistently the unit has been serviced. Those are the things that predict failure in this county.
Opened equipment in a house this age tends to carry its own history: compressors, capacitors, and control boards from service calls spread across years, not a factory-original system. Half the homes in Kent County, Michigan were built in 1977 or earlier (2020-2024 ACS 5-year). That pattern means the repair scope turns on what a contractor finds inside the unit and whether the parts it takes are still in production. A board or a motor for a system that has been through several service generations may not be a catalog pull. The age of the building is backdrop; the age and lineage of what is running in it is where the job gets priced.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad against an exterior wall, and it is where heat gets released to the outside air. The compressor lives inside that cabinet and is often where a contractor starts when the system is not cooling. A failed capacitor, a seized compressor, or a refrigerant leak will all trace back to that unit.
Inside the house, the air handler or furnace cabinet holds the evaporator coil, which is the indoor half of the refrigerant circuit, and the blower that moves air across it and through the ducts. The refrigerant lines run between the two units, and the thermostat on the wall is what tells the whole system when to run. A contractor checks each of these when tracing why the system is short-cycling, not cooling evenly, or not running at all.
The drawing shows a typical central AC layout, and a licensed contractor determines what applies to this specific house and system.

What HVAC Repair Looks Like in Kent 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.
What Kent County, Michigan Requires for This Work
Michigan issues the mechanical contractor’s licence by classification: HVAC equipment, ductwork, refrigeration, hydronic heating and cooling, and limited or unlimited heating and refrigeration service are each a separate classification a contractor has to hold.
Michigan requires a mechanical contractor’s licence: nobody may install, alter or service the regulated mechanical work unless they, or an employee, hold a licence from the department that has not been revoked or suspended.
Severe Weather Events in Kent County, Michigan
Extreme weather puts real strain on central AC systems. How hard a unit works, how often it cycles, and how long its components hold up are all shaped by the conditions outside, which is why local weather history is part of understanding repair demand in this area.
