Berwyn has roughly 12,000 owner-occupied homes, or 61.1% of households. The median home value is $286,000, and median household income is $75,235.

Cook County also had 8 tornado days in that period.

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 whether the diagnostic fee comes off the repair bill.
  • Have the model and serial number from the furnace label handy. Parts get ordered faster.
  • If the furnace is past 15, ask the tech to price both a repair and a replacement.
