Gary Housing Stock
Census figures put the median build year in Gary at 1957, so a typical house here has about 69 years on it. 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. Owners live in 47.4% of occupied homes, roughly 13,000 households. The median home value is $85,300, and median household income is $37,380. We use both figures to adjust labor and pricing for this page.
Between 2020 and 2025, NOAA's Storm Events Database logged 12 hail days and 37 days with damaging thunderstorm winds in Lake 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. Lake County also had 8 tornado days in that period. In Gary, 18.6% 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.
