Hammond Housing Stock
Half the homes in Hammond were built before 1952 (Census ACS median), so the typical house is 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. Hammond has roughly 18,000 owner-occupied homes, or 62.5% of households. With a median household income of $53,950 and a median home value of $141,700, local labor rates come out below the national middle in our model.
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.
