Four months of real heat, then long stretches of nothing
Champaign gets four months of cooling, June through September, with summer afternoons averaging 84°F. That is not a long season, but it runs hard while it lasts. The compressor and the fan motor carry that load for weeks at a stretch, then sit idle the rest of the year.
The storms here add their own wear. Champaign County has logged 70 hail events and 223 damaging wind events over the past ten years, with hail up to 3 inches recorded. Hail dents the thin fins on the outdoor coil, and wind drives debris into the unit or knocks it out of level. A homeowner usually notices it as weaker airflow, a system that runs longer than it used to, or the whole unit going quiet when it should be working.

A new air conditioner would save little on running costs in Champaign County, so the repair decision comes down to the unit's condition.
Estimates for a typical Champaign County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Illinois fuel prices and NOAA climate normals. Your home will differ.
Repair makes sense when a part like a capacitor or contactor has failed.
Replacement makes sense when the compressor has failed or the system uses R-22 refrigerant, which is no longer made.
In Illinois, HVAC licensing for homes is left to the cities and towns.
Whether a contractor in Champaign County needs a local license depends on the town. Some cities set their own licensing and testing for HVAC contractors, others don't touch it at all, and the address decides which rule applies. There's no statewide list or state exam behind any of it. Illinois leaves this entirely to city hall.
What does apply everywhere, city rule or not, is federal. Any technician who opens the refrigerant side of your air conditioner to repair it has to hold EPA Section 608 certification. That's not optional and it doesn't vary by town. It covers the part of the repair where refrigerant is handled, which is the part with real consequences if it's done wrong.

- Why is my AC not blowing cold air?
- Usually it means the coil is frozen or the refrigerant is low. A dirty filter blocks airflow across the coil, and once it ices over the air coming out turns warm even though the fan still runs. Low refrigerant means a leak somewhere in the line, and that's not something to top off yourself. Either way, a contractor needs to look at it, since running it in this state can damage the compressor.
- Why is my AC leaking water?
- Most likely the condensate drain line is clogged. Your AC pulls moisture out of the air as it cools, and that water is supposed to run out through a drain line to the outside. Algae and dirt build up in that line over time and block it, so the water backs up and drips inside instead. A frozen coil that's now thawing can cause the same thing, so if you noticed weak airflow before the leak started, mention that too.
- Why won't my AC turn on?
- Check the thermostat first. If the display is blank, it may need new batteries, or a breaker may have tripped. If the thermostat looks fine but nothing outside is running, the capacitor that starts the compressor may have failed, which is common after summers with a lot of heat and heavy use. That part is a straightforward fix for a contractor but not something to test yourself, since it holds a charge even when the power is off.
