If the attic exhaust fan motor ever wears out, the fan motor can usually be replaced without a complete installation of a new unit.

Savings in air conditioning costs far outweigh the cost of electricity for running the fan. The elimination of moisture and excessive heat extends the life of asphalt roof products.
