The main difference between an attic fan and a whole house fan is that an attic fan is designed to circulate air in a small space, such as an attic, while a whole house fan circulates air throughout the entire home. An attic fan typically has adjustable blades so it can be positioned at different heights depending on the size of the room or area being cooled, whereas a whole house fan generally has fixed blades for maximum coverage. Additionally, attic fans are usually powered by electricity, whereas whole house fans may use either electricity or solar power.
