Three months to earn its keep
Your air conditioner in Lapeer County only gets June through August to do its job, three months a year, with summer afternoons averaging 80°F. That's a short stretch of hard running after a long stretch of sitting still.
A tune-up before the season checks the refrigerant charge, the electrical connections, and the coil, so the system isn't fighting itself once those 80°F afternoons show up. Lapeer County has also seen its share of hail and wind over the past ten years, 12 hail events and 65 damaging wind events since 2015, and a unit sitting outside takes that weather straight on. A look at the coil and the cabinet catches damage before it turns into a bigger repair.

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.
That license is held by the contractor, not issued job by job, so the same license covers the person who comes to your house whether it's a tune-up or a full replacement. Michigan's Board of Mechanical Rules is the body that licenses and tracks these contractors, which means there's a state record behind the name on the van.
Maintenance on an air conditioner usually means checking the coil, the refrigerant charge, and the electrical connections, and any part of that work that involves opening the refrigerant side requires the technician to hold EPA Section 608 certification, a federal rule that applies no matter what state you're in. In Michigan, that certification sits alongside the state license rather than replacing it, so a contractor working on your system is answerable to both.

- What does AC maintenance include?
- A technician checks the refrigerant charge, cleans the outdoor coil, and tests the capacitor and contactor in the condenser. They will also check the evaporator coil, change or check the filter, and confirm the thermostat is calling for cooling correctly. Cleaning the coils matters most, since a dirty coil makes the whole system work harder to cool the same air.
- How often does an air conditioner need maintenance?
- Once a year, before the weather turns warm. Here that means getting it looked at in spring, ahead of the June through August stretch when the system runs hardest against 80°F afternoons. Waiting until summer means finding a problem after it's already hot in the house.
- Is AC maintenance worth it?
- Yes, because most breakdowns start as small problems that get worse if nobody catches them. A weak capacitor or a dirty coil will not stop your system right away, but it makes the compressor work harder until something fails. With only three months of real cooling season here, a summer breakdown means going without air during the hottest weeks of the year.
