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.
It ll reach down through the insulation it ll find all the little cracks and crevices in that ceiling space and it ll reach down into your house and it will start drawing off air conditioned air and actually drive up your cooling costs.
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.
Of course if the attic fan isn t working correctly and is running all year long that would be a significant problem.
