Macon County had 14 hail days and 23 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 2.5 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Macon County also had 7 tornado days in that period. In Decatur, 20.8% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk. Mention it when you call, since many companies put those calls first.

Illinois Licensing and Efficiency Rules
Illinois falls in the DOE's North region. New split central air conditioners must meet at least 13.4 SEER2, and heat pumps sold anywhere in the U.S. need 14.3 SEER2 and 7.5 HSPF2. Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Illinois the company should carry a state license or registration. Ask for both.
Before You Hire
- Ask what the emergency fee is before the truck is sent.
- If the CO alarm goes off, get everyone outside and call 911 or the gas company before you call an HVAC company.
- Maintenance plans often put members first in line for emergency calls.
