There are two very different designs in whole house fans. The oldest and cheapest are the big fans that Home Depot and others sell – the big 24, 30, 36, 42 and 48 inch fans selling for under $300 up to over $800. These mount in your hall ceiling, have louvres to hide them, and create more noise than more modern whole house fans.
There are 4 suppliers of more modern super quiet systems that mount high in your attic and are ducted down to your bedroom or hall ceiling.
Below are the best sources for attic mounted quiet and cool whole house fans. These are highlighted because they offer more modern designs. These are NOT the typical propellers sold by Home Depot for your hall ceiling. All of the systems shown below are designed for lower sound levels, better insulation and invisible operation.
AirScape offers several models. Their 1.7 features four 10 inch fans, pulls 1712 CFM on high speed. Airscape fans cost more per CFM because the unit includes a very effective motorized door.
Airscape includes a 2 speed wall switch, a 10 foot power cord, mounting hardware including gasket and screws, and white cube core grille.
Invisco is the first and only company to offer big fans mounted in your attic. You can get the same performance from Invisco as you can from Home Depot and Triangle. You will see CFMs including 3600, 4500, 6000, 10300, 14,500 and 18,200 all attic mounted and super quiet. Invisco has designed the first R60 damper system for colder climates. These are the first dampers to meet or exceed the 2012 IECC recommendation for new home attic insulation in zones 4, 5, 6 and 7. Until January 2012 zones 4 and 5 were R38. Then the rating was changed to R49.
Quiet Cool has many CFM ranges and the company has recently introduced their ES line of energy saving systems based on the use of ECM (Electronically Commutated Motors). The largest single fan they offer is 2850 CFM. To offer higher CFMs they put two, three, or four motors in the attic and duct them to central inlets.
Tamarack has the only ceiling mounted and motorized insulated doors in the industry. They are rated at R38 so they are useful in climate zones 1, 2 and 3. Most of Tamarack’s systems mount right in your ceiling.
