Is a whole house fan the same as an attic fan?
In respect to this, do attic fans make a difference?
Attic fans are particularly unknown. They are smaller, do not directly blow cool air, and are seen as accessories instead of necessities. They do, however, make a big difference in any home for a relatively low price compared to whole house fans, air conditioners, and even ceiling fans.
Likewise, is a whole house fan a good idea? When the conditions are right, cooling your home with a whole house fan consumes less energy than most air conditioning systems. It's efficient and effective. In most homes, you're better off not having a whole house fan at all and just running your air conditioner instead.
In this manner, does a whole house fan cool the attic?
In a nutshell, whole house fans are designed to run after sundown, using cool night air to ventilate and cool your entire living space. Attic fans are designed to run on hot sunny days to clear super-heated air from your attic. Both can be worthwhile, but they do different jobs.
When should you use an attic fan?
An attic fan can be used to cool down your living space any time the air outside is cooler than the air in your home. An attic fan pulls air in through open windows and doors while pushing hot air out of the home through attic vents.
