Three months of hard work in a short summer
Your air conditioner in DeKalb County only gets June through August to do its job, and it runs hard through all of it. Summer afternoons average 82°F, and the unit cycles on and off for hours to hold that line. The compressor and the fan motor take that load in three months instead of having it spread across a longer season.
DeKalb County has also seen its share of rough weather, with 105 damaging wind events and 27 hail events over the past ten years, one hailstone reaching 2.75 inches. Hail that size can bend the thin fins on an outdoor coil, and wind can rock the unit on its pad or drive debris into it. A tune-up checks the coil and the cabinet for that kind of damage before the next hot afternoon puts the unit to work again.

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.
In DeKalb County, whether a contractor needs a local license depends on the city or township the house sits in. Some municipalities in Illinois register or license HVAC contractors on their own. Others have no such rule at all. There is no statewide test or state record to check either way, so what applies to this job comes down to the address.
For AC maintenance, the part that is regulated everywhere is the refrigerant. If the technician opens the refrigerant side of the system to check charge or pressures, federal law requires that person to hold EPA Section 608 certification. That holds no matter what city the house is in. The certification is separate from any local license and does not depend on where DeKalb County falls on that question.

- What does AC maintenance include?
- A technician checks the refrigerant charge, cleans the condenser coil outside, and tests the capacitor and contactor that start the compressor and fan. They also check the evaporator coil, clear the drain line, and look over the electrical connections for wear. In DeKalb it is worth having them check the condenser cabinet itself, since hail and wind can bend fins or knock debris inside it, and this area has seen 27 hail events and 105 damaging wind events over the past ten years.
- How often does an air conditioner need maintenance?
- Once a year is the standard, done before the season it works hardest. In DeKalb that means scheduling it before June, since the unit only runs June through August here. A single yearly check catches a worn capacitor or a low refrigerant charge before it has to work through an 82°F afternoon.
- Is AC maintenance worth it?
- Yes, because most breakdowns trace back to something a technician could have caught, like a failing capacitor or a dirty condenser coil losing its ability to shed heat. With only three months of real cooling load here, a unit that skips maintenance can go a long time looking fine before a small problem turns into a no-cool call during those months. A yearly check also means someone is looking at the unit after hail or wind events, which DeKalb gets its share of.
