<human>: What's the difference between an attic fan and a whole house fan?
<bot>: The main difference between an attic fan and a whole-house fan is that an attic fan is designed to circulate air in an attic, while a whole-house fan circulates air throughout the entire home. An attic fan typically has a larger diameter than a whole-house fan, as it must be able to move more air. Additionally, an attic fan may have additional features such as adjustable speed settings, lighted switches, and remote controls for convenience.
