Main Differences Between a House Fan an Attic Fan
- A whole house fan ventilates air through the living space of a home.
- An attic fan ventilates the air through only the attic.
Which is Best?
Both attic and whole house fans have their place depending on location and the cooling/heating system that is installed.
Attic fans vent air from an attic space which cools it down from built up heat.
Once the attic is cooler in theory the home should also be cooler.
Whole house fans are located at the highest point in a home and have large fan blades that can quickly pull old stagnate air from the interior of a home.
Often the air is pulled from inside a home and into the attic which then blows it outside. Venting the air can also bypass the attic and simply be pushed outside.
A whole house fan can quickly cool down a home during the evening, night time, or any time the air outside is comfortable.
Since they can be setup to blow air into an attic they also do the job of an attic fan.
Whole house fans are also used in homes that need air flow and can move out stagnate stale air quickly.
For example, this helps in homes that have pets or smokers.
Both whole house fans and attic fans are cheap and easy to install.
They can benefit a home greatly depending on the scenario.
Using an attic fan can help reduce cooling costs in the summer venting hot air out of the attic.
Using a whole house fan can bring fresh air into a home quickly moving bad stagnate air outside.
This can be beneficial for many reasons from a hose with a lot of pets to a smoker looking for fresher air.
