How it Works
Our Whole House Fans utilize what already exists to create something offered nowhere else. Open two or three windows a few inches wide, turn on your QuietCool Whole House Fan, and experience fresh, cool air replacing your indoor air in 3-4 minutes. Your Whole House Fan will quietly pull air through the windows, into the attic, and out the attic vents giving you a cost effective way to keep your home cool and healthy.

Save up to 50-90% on A/C related costs and even more on preventative care that protects your attic, home, and A/C from costly damages with a QuietCool Whole House Fan.
