Chattanooga Housing Stock
Half the homes in Chattanooga were built before 1975 (Census ACS median), so the typical house is about 51 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. About 41,000 households here own their home, 53.1% of the occupied total. The median home value is $259,200, and median household income is $61,028. We use both figures to adjust labor and pricing for this page.
Between 2020 and 2025, NOAA's Storm Events Database logged 9 hail days and 44 days with damaging thunderstorm winds in Hamilton 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. Hamilton County also had 2 tornado days in that period.
