Many attics are hot, dry and feel much like a sauna throughout the hot summer days. Heat buildup in the attic makes it difficult to cool the home and may even cause damage to the roof materials. Simply installing an attic fan pushes out hot air to help save energy costs, reduces home deterioration and equalizes temperatures indoors. The fans are either gable mount or roof mount and powered by solar energy or electricity.
