Between 2020 and 2025, NOAA's Storm Events Database logged 14 hail days and 24 days with damaging thunderstorm winds in Merrimack County. The largest hail reported was 1.5 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. In Concord, 18.5% 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.
