Category: Insulation - Topic: Passive Venting Attic Fans

While passive venting systems disperse heat, attic fans are more efficient at cooling down the entire house. When attic temperatures hit a pre-set high, the fan, usually installed in the hallway, will pull in cooler air from outside and push warm air out through attic vents. The electricity it takes to operate the fan costs substantially less than running central air. Solar attic fans- the newest invention in the heating and cooling industry- are installed on the roofs of most homes and use energy from the sun to power a whole house fan as efficiently as electrical units. They cut down on utility costs, are environmentally friendly and don't take up as much room in the home.
