Between 2020 and 2025, NOAA's Storm Events Database logged 9 hail days and 46 days with damaging thunderstorm winds in DuPage County. 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. DuPage County also had 12 tornado days in that period.

Symptoms Worth a Service Call

  • The thermostat calls for heat and nothing happens
  • A yellow or flickering flame instead of a steady blue one
  • Cold air coming out of the vents
  • The burners light, then shut off a few seconds later
  • The blower won't stop running

What Moves the Price

  • Which part failed: a flame sensor costs far less than a control board or blower motor
  • Whether the part is still under the manufacturer warranty
  • The furnace's age and brand, which affect parts availability
  • Night, weekend or holiday rates
  • The diagnostic or service call fee

We raised the national figures about 40% for Wheaton using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.

What the Quote Should Cover

  • Replacing the part that failed
  • A test run through a full heating cycle
  • A diagnostic check
  • A safety and combustion check

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. A repair usually goes ahead without a permit, but the tech handling refrigerant must hold EPA 608 certification. Ask the company for its Illinois license or registration number before the visit.

Before You Hire

  • Have the model and serial number from the furnace label handy. Parts get ordered faster.
  • Ask whether the diagnostic fee comes off the repair bill.
  • Check the filter, the thermostat batteries and the breaker first. Those three cause a surprising number of no-heat calls.
