A whole house fan pulls cooler air from the outside, and pushes hot air out of your attic, allowing you to run your air conditioner less often. QuietCool's line of whole house fans allow you to do this more efficiently and quietly than other manufacturer's whole house fans. 

The QuietCool Classic CL-2250 whole house fan has a primary benefit of running very quietly.  The sound level from this fan is only 44 decibels on high.  One reason it is so quiet is the included acoustical insulated flex duct.

This whole house fan can also be easily installed, in most cases in about an hour.  The QC CL-2250 mounts in the attic, by hanging from the rafters.  Included in the box is a template to cut the opening for the grill and the grill can be mounted horizontally or vertically To see how easy installation is, download the Installation Manual. The QC CL-2250 also has a built-in ceiling grade damper to prevent drafts from entering the living space.

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.
