Installing a QC CL-4700 inline whole house fan allows you to efficiently cool your home and attic. A whole house fan works is by pulling cooler air from the outside, and pushing the hot air trapped in your attic out,  allowing you to run your air conditioner run less often, which will help save you money.

The primary benefit of the QuietCool fans is that they run very efficiently. Installing this fan is very easy, you do not have to cut your joists, it mounts between 16 or 24 inch on center joists.  This whole house fan also runs very quietly.

This whole house fan is also easy to run.  You may use an optional remote control or a hard wired switch. This whole house fan plugs into a wall receptacle which makes installation even easier.

How to Find Out How Much Net Free Venting Area You Have in Your Home:
1. Measure All the Vents You Find In Your Home
If you were to measure (length x width) of each vent in your homes attic/roof, you would have a ball park idea of how much roof and attic venting your home has.

2. Measure In Inches, Then Convert to Square Feet
Take The Total Area Of Your Vents In Inches And Convert To Sq. Ft By Dividing By 144

3. If Your Vents Are Screened Take Your Total Area and Cut It In Half!
Since most vents are screened, which can obstruct 1/2 of the air flowing out of the once you have your gross total area of venting, multiply that number by .5 to get your Net Free Area Of Venting.

Example: If we take one 12″ x 12″ gable end vent and multiply the length (12″) by the width (12″) we would have a total of 144 square inches of venting. To convert to sq. ft. we would divide by 144 (since there are 144 sq. inches in one square foot). When we divide 144/144 we see that equals 1 sq. ft. But since our vent is screened, we would take our 1 sq. ft and cut it in half. That leave us with .5 sq. ft of net free venting.
