Leander Housing Stock
The median Leander home dates to 2012, according to the Census ACS. That makes the typical house about 14 years old. Newer homes are built tighter, so oversized equipment is a common problem. It short-cycles, wastes energy and leaves rooms clammy. About 18,000 households here own their home, 75.6% of the occupied total. With a median household income of $140,180 and a median home value of $470,700, local labor rates come out above the national middle in our model.
NOAA storm reports for Williamson County show 29 hail days and 14 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 4 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. Williamson County also had 3 tornado days in that period.
