Three months of real heat, then nine months off
Your air conditioner in Allegan County works hard for a short stretch. June through August, with afternoons averaging 81°F, it runs about as much as it will all year, then sits idle the rest of the time. That kind of stop and start is hard on a system. The parts that get exercised hardest, the compressor and the fan motor, sit through fall, winter, and spring without turning over, then get asked to start up on the first hot day.
A tune-up before that first hot stretch catches what nine months of sitting can hide, like a capacitor that has weakened or a contactor with pitted contacts. It also means the system is not starting its busiest season already behind.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.
Michigan requires HVAC contractors to hold a state license.
The Board of Mechanical Rules licenses the contractor, not the visit. That means the state tested this contractor and keeps a record of them, and that record follows the business, not the specific job on your air conditioner.
For a maintenance visit, the part of the job the state license does not reach is anything involving refrigerant, and that is covered separately. Any technician who opens the refrigerant side of your air conditioner, to check charge or recover refrigerant, has to hold EPA Section 608 certification. That is a federal requirement, the same in Michigan as anywhere else in the country.

- What does AC maintenance include?
- A technician checks refrigerant charge, cleans the condenser coil, and tests the capacitor and contactor in the outdoor unit. Inside, they check the evaporator coil and the condensate drain, since a clogged drain can shut the system down or cause water damage. They also check the thermostat calls for cooling correctly and inspect electrical connections for wear. Cleaning or replacing the filter matters too, since a dirty filter restricts airflow across the coil and makes the whole system work harder.
- How often does an air conditioner need maintenance?
- Once a year, before the season it has to work hardest. Here that means getting it checked before June, since cooling season runs June through August and afternoons average 81°F. A yearly check catches a weak capacitor or a low refrigerant charge before it fails on a hot afternoon instead of during it.
- Is AC maintenance worth it?
- Yes, because most breakdowns trace back to something a technician would have caught, like a failing capacitor or a coil coated in dirt that makes the compressor work harder than it should. A unit that is checked yearly is also less likely to quit during the stretch it actually gets used, which here is just three months. Regular maintenance also gives a contractor the chance to spot corrosion or loose wiring, the kind of wear that wind and storms can accelerate on an outdoor unit sitting exposed year round.
