Three months to do the whole year's work
Your air conditioner in Lansing only runs June through August, with summer afternoons averaging 80°F. Outside of that stretch it sits idle, and idle time is when small problems settle in unnoticed. A capacitor weakens. A contactor's points pit. Refrigerant drops a little from a slow leak. None of that shows up until the first hot day, when the unit has to start working hard right away.
A tune-up before summer catches those things while they are still small. It also covers what the weather here does from the outside in. Ingham County has logged 10 hail events and 21 damaging wind events over the past ten years, with hail up to 2 inches. Wind can knock the outdoor unit out of alignment, and hail can bend the fins on the coil, so checking the cabinet and coil is part of the job too.

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 is the state agency that licenses HVAC contractors in Michigan. The license belongs to the contractor, not to any single job, so it covers this maintenance visit the same way it covers a full install.
If the technician opens the refrigerant side of the air conditioner to check the charge, federal law requires them to hold EPA Section 608 certification, the same as it would anywhere else in the country. That certification is separate from the state license. One says the contractor is licensed to do this work in Michigan. The other says the person on the job has been tested on handling refrigerant without releasing it into the air.

- What does AC maintenance include?
- A contractor checks refrigerant pressure, cleans the condenser coil, and tests the capacitor and contactor in the outdoor unit. Indoors, they check the evaporator coil and the condensate drain, since a clogged drain is one of the most common reasons an AC stops cooling. They also check the thermostat and confirm the system cycles on and off the way it should. The filter gets checked 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 is standard, done in spring before the cooling season starts. Lansing only needs cooling June through August, so scheduling it before June gives a contractor time to catch a worn part before summer heat puts real load on the system. A once a year visit is enough to catch most problems before they turn into a breakdown on a hot day.
- Is AC maintenance worth it?
- Yes, because most breakdowns trace back to something small that grew into a bigger failure, like a dirty coil making the compressor run harder than it should. A yearly check catches that early. It matters more here than in places with mild summers, since Lansing only needs cooling June through August, and a system that fails during those months has little time left to get fixed before the heat is gone. Regular maintenance keeps the system running the way it was built to for the summers it does have.
