The Comfort Stream is the only whole house comfort ventilator that we sell.  It offers a unique, distributed approach to hybrid, natural cooling.  It is the only whole house comfort ventilator that is designed to be vented directly to the outside.  We are proud that Comfort Stream is Certified by HVI and included on California's Title 20, Appliance Efficiency List.  (Ask other manufacturers when their fans will be Certified and Listed.)  Please check out the details and call us if you have questions.

Comfort Stream Whole House/Utility Fan
Comfort Stream whole house fans
Our product - Our price! $1,449.00

Enhancing natural cooling can be a lot more pleasant than sitting in unnaturally chilled, air conditioned air unless it is unbearably hot and humid outside.  The Comfort Stream™ can be used as a whole house fan, home comfort ventilator, or utility fan, venting four rooms to the outside.  When it is used as a whole house fan or whole house comfort ventilator, it amplifies a natural cooling effect, working as "hybrid cooling system™" when it is cooler outside than it is inside.  Unlike the majority of whole house comfort ventilators, the Comfort Stream was engineered to vent directly to the outside.  And the inlets to the Comfort Stream can be located in each of four rooms, working effectively whether the room door is open or closed.  Because the fan is mounted remotely, the powerful flow of air drawn through the grille has been measured at the Environmental Systems Laboratory at Texas A&M University to be a mere 1.9 sones, just a bit louder than a quiet refrigerator, about the same level as a computer fan.  The Comfort Stream is powerful enough to change all the air in a 2500 square foot house in just 12 minutes.  How quickly it cools the house will depend on how cool it is outside.
