Three months of hard running, then nothing
Your air conditioner in Moline works three months a year, June through August, with afternoons averaging 83°F. That is a short window to earn its keep, and it runs hard through all of it. Then it sits the rest of the year, and whatever wore loose in summer has months to turn into a real failure before the next hot stretch finds it.
Rock Island County has also logged 87 damaging wind events and 34 hail events over the past ten years, with hail up to 3 inches. That kind of weather can bend the fins on the outdoor coil or knock the unit out of alignment without leaving any sign you'd notice from the ground. A tune-up is when a contractor finds that damage, along with the parts worn from a summer of steady running, before next summer asks more of the unit than it can give.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.
In Illinois, HVAC licensing for homes is left to the cities and towns.
Illinois does not license HVAC contractors at the state level. Whether a contractor needs a local license to work on your air conditioner depends on whatever rule the county or the nearest city or town has set, not a credential the state tracks.
For maintenance on an air conditioner, the part federal law covers is the refrigerant. Any technician who opens that side of your system, even for a routine check, has to hold EPA Section 608 certification. That is a federal requirement, not a state or local license, and it applies the same way here as it does everywhere else in the country.

- What does AC maintenance include?
- A technician checks refrigerant levels, cleans the condenser coil, and tests the capacitor and contactor that start the compressor. They also check the airflow across the evaporator coil, inspect the condensate drain for clogs, and confirm the thermostat is calling for cooling correctly. A dirty coil can't shed heat the way it should, and a weak capacitor or a low charge is the kind of thing that leaves you without cooling on an 83 degree afternoon if it isn't caught first.
- How often does an air conditioner need maintenance?
- Once a year, ideally before the season's first hot stretch. Homes here only run the AC from June through August, so getting it checked before June means it's ready for those three months instead of failing partway through them. Waiting until a hot afternoon to find out something's wrong means going without cooling while it gets fixed.
- Is AC maintenance worth it?
- Yes, because most of what causes a summer breakdown is something a technician can catch ahead of time. A weak capacitor, a low refrigerant charge, or a dirty coil all show up during a check, and any of them can leave you without cooling on an 83 degree afternoon if they don't get caught. With 34 hail events and 87 damaging wind events recorded here over the past ten years, maintenance is also a chance to look over the outdoor unit for dents or bent fins from the last storm.
