Cicero Housing Stock
Census figures put the median build year in Cicero at 1938, so a typical house here has about 88 years on it. Many houses that age were built with hot-water or steam heat, and plenty still run cast-iron boilers and radiators. Cicero has roughly 14,000 owner-occupied homes, or 54.6% of households.

Between 2020 and 2025, NOAA's Storm Events Database logged 27 hail days and 75 days with damaging thunderstorm winds in Cook County. 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.

Illinois Permits, Efficiency Rules and Rebates
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. Equipment replacements in Cicero generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Illinois license or registration number and a certificate of insurance with the quote. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- Ask your gas or oil company about rebates on condensing boilers.
- For a steam system, hire a contractor who works on steam regularly.
