Kane County also had 11 tornado days in that period.

Symptoms Worth a Service Call

  • Ice on the refrigerant lines or the indoor coil
  • The system cycles on and off every few minutes
  • The outdoor unit hums, but the fan doesn't spin
  • The AC runs, but the air coming out is warm

What Moves the Price

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

  • Swap the air filter and check the breaker before you call anyone.
  • 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.
