NOAA storm reports for Pinellas County show 2 hail days and 18 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 1 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost. Pinellas County also had 12 tornado days in that period. In Largo, 26.8% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk.
