Skokie Housing Stock
Half the homes in Skokie were built before 1959 (Census ACS median), so the typical house is about 67 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 18,000 households here own their home, 74.1% of the occupied total. With a median household income of $93,550 and a median home value of $368,600, local labor rates come out above the national middle in our model.
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. In Skokie, 20.4% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk. Mention it when you call, since many companies put those calls first.
