There are surprisingly few actual tests of solar attic fans posted on YouTube. So we ran our own test.
What we proved is that solar attic fans actually do drop the temperature in the attic. Does it actually reduce your energy bills? I haven’t done a comparison, but it’s almost impossible to since the summer of 2011 in Texas (Dallas) was much hotter than 2012. So it’s difficult to get an “apples to apples” comparison.
However, lowering attic temperatures and increasing ventilation is recommended by contracting and energy experts all over the United States.
But I thought you would find this video interesting and unique.
