NOAA storm reports for Bexar County show 35 hail days and 24 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 5.5 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. Bexar County also had 2 tornado days in that period.
