Compressor wear, capacitor fatigue, and contactor pitting in Wayne County systems rarely trace back to a single bad event. 189 severe weather events were recorded in Wayne County, Michigan between 2015 and 2024. At that rate, severe weather is a standing condition for equipment here, and a contractor working a repair needs to check the parts that carry electrical and mechanical stress under load surges before drawing any conclusion about what failed and why. A quote built without that inspection can miss the real scope entirely.
Half the homes in Wayne County, Michigan were built in 1956 or earlier (2020-2024 ACS 5-year). A house built around that year was designed for a different kind of cooling, if any at all, and the ductwork it contains reflects that. When a central AC system in a house like that fails, the opened unit tells a contractor what broke. The ductwork tells them whether a straightforward repair holds or whether restricted airflow has been wearing the system down from outside the equipment itself. Parts availability is its own question once the system is open. But the duct condition is what a contractor has to account for before the repair bill makes sense.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and it holds the compressor and condenser coil. These are the pieces a contractor reaches first when a system stops cooling. The compressor is the heart of the refrigerant circuit, and the condenser coil is where heat gets shed to the outside air.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower that moves air across it. The refrigerant line set runs between the two cabinets, and the thermostat on the wall tells the whole system when to run. A fault in any of these can look like a failed compressor until a contractor traces it properly.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply and what condition they are in for your specific house.

What HVAC Repair Looks Like in Wayne 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.
Licensing and Legal Requirements in Wayne County, Michigan
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 Wayne County
Extreme weather puts real strain on cooling equipment. How hard a system works over its lifetime depends heavily on local conditions, which is why repair needs in Wayne County look different from those in quieter climates.
