When not in use, your house fan leaks conditioned air into the attic. It works great for those few days before summer heat hits and you're not quite ready to turn the AC on. However those days seem to be few and far between. The house fan is great idea for those days if you actually use it, but most people we've surveyed (unscientific) rarely turn it on. Here is a quick easy way to seal off the fan so no air travels through the vents.

You can simply use window plastic stretched across if you don't plan to use the attic fan any time in the future. Another way is to purchase a kit from Batticdoor.com (http://www.batticdoor.com/louvercoverdetails.html) that is attached with velcro giving you the ability to remove anytime you need to utilize the attic fan. Installation is fairly simple, just follow these instructions.

1 . First get yourself a good ladder and measure the house fan. Take a clean washcloth and run around the perimeter to ensure good adhesion for the velcro.

2. Cut you velcro to just the right length and adhere to the edge of the house fan. Create a complete seal around the frame to ensure no air will be able to escape through.

3. Now cut your foam insulation to fit the house fan exactly right to the edge. Measure twice, cut once because you only have one piece!

4. Now stick the side B velcro to the backside of your foam insulator.

5. Install seal in place making sure to press firmly into place.

6. Wait for wife inspection...LOL
