The Importance of Attic Exhaust Fans for Temperature Regulation and AC Efficiency

Attic exhaust fan needed. Well this summer the heat build up in the two attics will help getting out, with help from my son we installed two exhaust fans that are thermostatically controlled, these are set to come on when the attic temps reach 90 degrees.

Last summer the temps were so hot that the AC ducts were dripping water, the ductwork insulation was no match for temperatures above 115 degrees.

Having metal roofing concerned me as this would be my first experience however really turned out to be fairly easy, the roof cap was screwed down and once it was raised the fan was able to slide down from the top as seen in the photos.

The second story was done different as we used a side vent which I will post later.
