Summer Heat Can’t Compete with Solar Attic Fans

As spring’s fluctuating temperatures give way to soaring summer digits and triple-digit energy prices, a solar attic fan can reduce the heat load in your home, business, barn, shed or other structure. Heat from the sun is absorbed into a roof and accumulates in a structure’s attic, reaching temperatures as high as 160 degrees during the summer. That heat then permeates into living spaces. Actively ventilating an attic or under roofing keeps temperatures down and reduces the amount of energy needed to cool the building. READ MORE

Solar Attic Fan Info has some great solar attic fan information. I had no idea what fan to buy and their solar attic fan sizer made the decision easy.

One major caution with attic fans, make sure your attic vents are clear before using them. If your vents are plugged, the fan will suck in the conditioned air from in the home out. Thus your AC will work more an harder to keep the house cool, and actually cost you more money than prior to the fan installation. If the vents are clear and outside air flows properly, the fan will work as designed. Not nearly enough installers know this, or check for it, so make sure you check this yourself to ensure proper use.
