I worked with coolmygarage.com and I was telling them about the room above my garage was hard to get cool and it is my daughter’s room. They explained that the heat from the attic as well as the garage was causing the problem, and they recommended the SWGF-14 garage Fan. I had it installed and over the next few days I really noticed that my daughter’s room was about 8 degrees cooler. And the garage was about 20 degrees cooler. I would recommend coolmygarage.com and their products to anyone with a problem such as mine.
