Wind and hail losses are the most frequently claimed homeowner’s insurance peril, causing approximately $1 billion in damages each year according to the Insurance Information Institute. HVAC systems, particularly condensing units and package units, have a high risk of hail damage.

When hail (or any other foreign object) strikes the coil, these fins can be bent and flattened, eventually reducing the ability for the coil to transfer heat efficiently.
