Louisville Housing Stock
Half the homes in Louisville were built before 1970 (Census ACS median), so the typical house is about 56 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 159,000 households here own their home, 60.6% of the occupied total. The median home value is $221,500, and median household income is $64,731. We use both figures to adjust labor and pricing for this page.
Between 2020 and 2025, NOAA's Storm Events Database logged 10 hail days and 45 days with damaging thunderstorm winds in Jefferson 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. Jefferson County also had 8 tornado days in that period.
