Cook County had 27 hail days and 75 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 2.75 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. Cook County also had 8 tornado days in that period. In Tinley Park, 20.1% 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.

Symptoms Worth a Service Call

  • The breaker trips when the AC kicks on
  • Water pooling around the indoor unit
  • The outdoor unit hums, but the fan doesn't spin
  • The system cycles on and off every few minutes
  • Ice on the refrigerant lines or the indoor coil

What Moves the Price

  • Whether the equipment sits in a tight attic or on a roof
  • The part: a capacitor costs a fraction of a fan motor, and a compressor costs far more than both
  • Refrigerant type and how many pounds it takes
  • Nights, weekends and holidays
  • The service call or diagnostic fee

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

  • If the compressor is gone on an older unit, get a replacement quote before you pay for the repair.
  • Ask for the per-pound refrigerant price before any work starts.
  • Swap the air filter and check the breaker before you call anyone.
