Joliet Housing Stock
Half the homes in Joliet were built before 1986 (Census ACS median), so the typical house is about 40 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. About 37,000 households here own their home, 73.1% of the occupied total. Homes here have a median value of $248,600 and households a median income of $88,026. Those two numbers drive the labor adjustment in our estimate.
Between 2020 and 2025, NOAA's Storm Events Database logged 16 hail days and 48 days with damaging thunderstorm winds in Will County. The largest hail reported was 1.75 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. Will County also had 11 tornado days in that period.
