A contractor called out to repair a central AC system in Van Buren County has to figure out what actually wore the equipment down. 59 severe weather events were recorded in Van Buren County, Michigan between 2015 and 2024. At that rate, severe weather is an occasional fact of life here, and it rarely accounts for what a compressor or capacitor does after years of ordinary summer use. Age and the quality of the original installation are what a contractor checks first, because those are the variables that explain most failures in this area.
Ductwork in housing this old carries a long record of patch repairs, seal failures, and accumulated debris that a contractor finds once they get inside a system. Half the homes in Van Buren County, Michigan were built in 1978 or earlier (2020-2024 ACS 5-year). What that means for a repair call is that the fault in the equipment and the condition of the duct system feeding it are rarely unrelated. A contactor who opens the unit and finds a coil caked with material drawn through compromised ductwork is diagnosing a different repair than one where the ducts are intact. Parts availability for equipment running in stock of this age is a separate question the contractor has to answer before any quote holds.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit is usually the first thing a homeowner notices, sitting on a pad beside the house. It holds the compressor and condenser coil, and when either one fails, the system stops shedding heat altogether. The air handler or furnace inside the house holds the evaporator coil and blower, and a fault there shows up as weak airflow or a system that runs but never cools.
The refrigerant lines run between the two units, and a leak anywhere along them starves both coils of the charge they need to do their work. The thermostat and the condensate drain round out what a contractor looks at: a bad thermostat can mimic almost any system fault, and a blocked drain will shut the system down before anything mechanical fails.
The drawing shows a typical layout, and a licensed contractor determines what applies to this particular house.

What HVAC Repair Looks Like in Van Buren 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.

Severe Weather Events in Van Buren County
Weather puts mechanical load on cooling equipment, and that load accumulates differently depending on where the equipment runs. For Van Buren County homeowners, local conditions shape how hard a central AC system works and how quickly that stress shows up as a repair need.
