Four months of hard summer heat in Decatur
From June through September your air conditioner runs most days, working against afternoons that average 84°F. That kind of steady demand wears on the compressor and the capacitor that starts it, and a weak capacitor is a common reason a unit hums but won't kick on.
Decatur also gets its share of severe weather. Macon County has recorded 47 hail events and 109 damaging wind events over the past ten years, with hail as large as 2.5 inches. Hail that size can dent or bend the thin fins on your outdoor unit's coil, and high winds can knock the unit out of level or send debris into it. Either one can show up as an AC that runs but doesn't cool like it used to.

A new air conditioner would save little on running costs in Macon County, so the repair decision comes down to the unit's condition.
Estimates for a typical Macon 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.
Macon County does not run its own HVAC licensing program, and Illinois leaves the question to individual cities and towns. Whether a contractor needs a local license here depends on the city or township the house sits in, not on any statewide standard. There is no state record or state exam behind the work, only whatever the local building office requires, if anything.
For a repair like this, the protection that does apply comes from the federal government, not the state. Fixing an air conditioner means opening the refrigerant side of the system, and the technician doing that work has to hold EPA Section 608 certification, no matter what city the house is in. That certification is federal, separate from anything Decatur or another Macon County town might require on top of it.

- Why is my AC not blowing cold air?
- The most common reason is a dirty air filter choking off airflow across the coil, which can lead to it icing over. Check the filter first and replace it if it is gray with dust. If the filter is clean and you still get warm air, the system may be low on refrigerant from a leak, or the outdoor unit's compressor may not be running, and either one needs a contractor to look at it.
- Why is my AC leaking water?
- Warm, humid air runs across your AC's evaporator coil all summer, and the water that condenses off it is supposed to drain outside through a condensate line. When that line clogs with algae or dirt, the water backs up and drips inside instead, usually near the indoor unit. A clean filter helps prevent this, since a dirty one lets dust reach the coil and drain line. If the coil itself has iced over and is now melting, that points to restricted airflow or low refrigerant, and that repair needs a licensed contractor.
- Why won't my AC turn on?
- Start with the thermostat. Make sure it is set to cool and set below the room temperature, and check that its batteries are not dead. If the thermostat looks right, check your breaker panel, since a tripped breaker will shut the whole system down. With 109 damaging wind events recorded here over the past ten years, a breaker trip after a storm is worth ruling out before assuming something inside the unit has failed. If the breaker is fine and the system still will not start, a contractor will need to check the capacitor or the control board.
