Question: what is the difference between a whole house fan and an attic fan?
Answer: An attic fan is installed in the attic and blows hot air out through a roof-level or gable vent. Outside air is pulled through roof and soffit 1 vents, keeping the attic cooler. ... Even though it is also in the attic, a whole house fan is installed in the ceiling of the home, usually in the ceiling of a central hallway.
