An attic fan may significantly decrease the amount of heat that leaves your home through the roof. The excessive California heat can damage the shingles on your home if you do not have an attic fan, which can in turn decrease the lifespan of your home and potentially your home value as well. An attic fan circulates the air and removes hot air. This also can decrease moisture damage by creating airflow to dry humid areas in your attic.
An attic fan could also decrease your utility bills by supplementing your air conditioning’s cooling power. An attic fan helps keep your attic cool so your AC doesn’t have to work as hard, and consequently reduces your electric bill.
