A solar attic fan works by replacing the hot air inside with the cold air outside. Little by little, the residing area can get cooler, ensuring reduced electrical energy consumption. In cold times, there are inclinations for moisture to build-up as well when the hot air inside your home meets with the cold temperature underside of the roof. Moisture breeds molds, which can damage your home. The solar attic fan solves this trouble by way of replacing the hot air inside for the cold air inside. This way, you will have a drier roof and attic.
