How To Reduce Heat In Attic

Anyone who's ever done work or contracted to do work in an attic or confined crawl space knows how difficult that work can be.  One wrong misstep and you're falling through the ceiling or bruising your head on an exposed truss beam.  But the real threat is the heat.  In our Florida summer months, outdoor temperatures can easily reach the mid or high 90's every day, which means attic temperatures swell to 110-120 degrees F.

The last time I did work in my attic, I attempted to wing it. I said to myself "If I'm quick enough, I can get up there and get out before the heat gets me too badly." To say I was wrong would be a vast understatement. As soon as I pulled myself into the crawlspace I began pouring sweat and it was difficult to even breathe. It was like the mother of all saunas, and I needed a solution. How do you reduce heat in the attic?

Turning to professional equipment, I learned about Vortex Axial Fans. These fans are ducted up into the crawl space, right up through the access point. I made sure to use a piece of wire to attach the end of the duct onto a truss beam so I wouldn't risk disturbing the insulation. After that I turned the fan on and it immediately began sucking out the hot attic air. I let the fan do it's thing for about 45 minutes to an hour, and once I got back up into the attic, there was a noticeable difference in temperature. Not only had the stifling heat been reduced, but the humidity in the air was much less noticeable. The attic felt dryer, the air more breathable, and while things weren't exactly comfortable up there it really helped me stay up there as long as I needed to get the job done properly.
