The kind that vent the hot air out of the attic? (As opposed to the large kind installed in ceilings to draw air thru windows into the house).
We have a HUGE attic, really tall. Our roof is metal and dark green (mistake). We live in East Texas and the temps in my attic are probably around 130 or 140 or so, with the outside temps reaching nearly 100 every day. With those extremes, I don't know if an attic fan would do anything or not. Maybe more than one?
We've got to do something! Our electric bill the past couple of months has been nearly equivalent to out two car payments!!! Our AC literally runs all day without cutting off because the temps in our (new) house reach 80. We have a couple of west facing windows and several south facing ones as well, but the west facing seem to cause the most warming. We keep the blinds shut, ceiling fans on, and an extra fan on in the worst room. We have insulation blown into the attic and double pane windows. We're hot at night (like to sleep pretty cool), and our electric bill is outrageous! Just thought about adding the attic fans to our list of things we are doing to help -- IF, they work. TIA!
Off to scour the house cooling thread to see if I missed an idea!
