Humble Beginnings


One day in 1999, our founder and inventor — an electrical contractor by trade — was installing a traditional whole house fan into a customer’s home when the customer exclaimed, “I wish someone would invent a quiet whole house fan!”

where it all began


Just like every great American invention that begins in a garage, our founder tinkered and tweaked his prototype QuietCool Whole House Fan until he had a workable, sellable product. The QC‑1500 became the first QuietCool Whole House Fan to come to the market in 2004.
