Three months of hard running, then months of sitting idle
Your air conditioner works for its living from June through August, and Grand Rapids summer afternoons average 81°F. That is not extreme heat, but it means the compressor runs for hours at a stretch on the hot days, and it does that for three months straight before it sits unused the rest of the year.
Kent County has also seen 56 damaging wind events and 11 hail events over the past ten years, one hailstone as large as 1.75 inches. Wind can rock the outdoor unit on its pad or bend the cabinet enough to let water and debris in. Hail dents the fins on the outdoor coil, and bent fins block airflow across it. A tune-up checks the coil and the fins for that kind of damage, and checks that the unit still sits level after a storm has moved it, before the next hot stretch asks the system to run flat out.

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.
Michigan issues that license through the Board of Mechanical Rules. It belongs to the contractor as a business, not to any single job, so the same license covers every service call they run, this one included.
For a maintenance visit, that license is what puts the contractor in your home at all. If the technician opens the refrigerant side of your air conditioner, checking the charge or the coil, they also need EPA Section 608 certification, which is federal and applies the same way in every state. On this job you have Michigan's license on the contractor and the federal certification on whoever handles the refrigerant itself.

- What does AC maintenance include?
- A technician checks refrigerant pressure, cleans the outdoor coil, and tests the capacitor and contactor that start the compressor. They also check the fan motor, inspect the wiring for wear, and confirm the thermostat is calling for cooling correctly. Outside, hail and wind can bend fins or knock debris into the unit, so the coil and cabinet get a look for that kind of damage too. Inside, the filter gets checked and the drain line gets cleared so condensation has somewhere to go.
- How often does an air conditioner need maintenance?
- Once a year, ideally before the weather turns warm. Grand Rapids only asks the system to run June through August, but that check still matters every year because a capacitor or a dirty coil does not wait for the busy months to fail. Doing it each spring means any problem shows up before an 81°F afternoon puts real load on the system.
- Is AC maintenance worth it?
- Yes. A yearly check catches a weak capacitor or a dirty coil before it causes a breakdown on the first hot day. It also keeps the system running the way it was designed to, since a dirty coil or low refrigerant makes the compressor work harder for the same amount of cooling. A contractor can walk through what your specific unit needs and price the visit from there.
