Attic fans worth it.

Are attic fans worth it. Good insulation reduces fan effectiveness. If you have good continuous soffit venting and a ridge vent then any type of attic fan may be totally unnecessary.

If the attic fan keeps the house cool enough so that the owners leave the ac off there is almost certainly an energy benefit. The problem with making a definitive statement on attic fans is that every house is different. However the utility of attic ventilation fans is actually quite a controversial topic.
