Attic Fan Direction

However the utility of attic ventilation fans is actually quite a controversial topic.

Attic fan direction.

Whole house fans are used to blow hot air out of the attic by sucking cool air through the house up though the whole house fan and out though the gable vents in the attic. Quietcool attic fans work almost everywhere almost anytime. These fans are usually wired to run in one direction. Attic ventilation fans whether hard wired or powered by their own solar panels seem like a low cost and effective way to help keep your house cool.

The fan is warranted for five years draws a mere 3 2 amps and is capable of handling an attic area up to 1500 sq. With an attic fan you can cool the attic to the same temperature as it is outside greatly reducing the house from heating as quickly. The downside of attic ventilation fans. Most houses only have one gable fan at one end and a vent the same size as the fan at the other end and of course the soffit vents.

Good insulation reduces fan effectiveness. If the vent fan is only pulling out of the garage and not the attic space then it wouldnt help the attic much which is what you want to cool. During the summer an attic can be 40 to 50 hotter than the outside temperature which in turn heats up the house very quickly.
