Chicago Housing Stock
The median Chicago home dates to 1952, according to the Census ACS. That makes the typical house about 74 years old. Houses that old often still have duct runs sized for an old coal or oil furnace and 60- or 100-amp electrical panels. Both can add cost when new equipment goes in. About 522,000 households here own their home, 45.5% of the occupied total. The median home value is $315,200, and median household income is $75,134. We use both figures to adjust labor and pricing for this page.
NOAA storm reports for Cook County show 27 hail days and 75 days with damaging thunderstorm winds over the six years from 2020 to 2025. 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 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
- Maintenance plans often put members first in line for emergency calls.
- Keep space heaters away from curtains and bedding, and never heat the house with a gas oven.
- Ask what the emergency fee is before the truck is sent.
