We have recently purchased an older home, built in 1931. Traditional whole house fans were popular in the 1950s, before A/C was common, mostly in the South and Midwest. Louvers open when the fan is running and close to seal the hole when it is not. While there are many different types and styles of these fans available in the marketplace, if you are looking to purchase a whole house fan – consider investing in a system that is whisper quiet, easy to install and requires no maintenance. If I open the attic access panel, the louvers open fully and its noticeably quieter. ... it won't >> open the louvers I think, which are just sucked open. fuse (or worse?). Whole-house fans usually have automatic louvers. The fan is as far as possible from the bedrooms. Like a box unit or a ceiling fan, a whole house fan cools down your house. Most whole house fans tend to be 24 or 30 inches. Usually the heavier the fan and louvers, the less of a problem this will be. They also rattle a bit. Access panel opening is ~7.5sf. I have a 36" whole house fan in the eave with a screened louver in front of the fan and a draft operated register in the ceiling in the center of the house. The fan works great if we prop the louvers open. Now the problem is we don't know how to accurately measure. In order to achieve cooling in these hot, humid climates (imagine a night that stays hot and sticky all night long) the air must move fast enough to create evaporative cooling on the skin (like a fan blowing right on you on a hot day). This type of fan is installed in the ceiling, and louvers open when the fan is turned on. There is a belt-driven whole house fan in the attic that we would like to get working again. It moves cool air in and moves hot air out at the same time. Open windows if the shutter rattles. So that tells me the #'s are about right and that I need at least 7-8sf of add'l vent space. We do not know when the fan was installed or who made it - however, it is a very large whole house fan - 42" blades with 46" frame. When we measure the shutter cover in place now we get odd measurements. Newer whole-house fans are available that have a flow range between 1,000 and 3,000 cfm. Make sure there is at least 30 inches of clearance above the blades of the fan, or air will be forced back through the shutter. Re: Whole house fan - possible to add variable speed? Whole house fans pull the air into your house and through any available open windows. We were told to replace the shutter. Do not put the fan in the bedroom. The traditional whole-house fan is fairly large and noisier than small fans, but can move between 4,000 and 7,000 cfm of air. More air helps the shutters open all the way. Re: Whole house fan - possible to add variable speed? They then push it out through your attic forcefully. I installed one of these fans in a house near Chicago, and frankly, the overall insulation of the house was poor enough that there would be no point to insulate just one 2x2 foot bit of the ceiling. It makes too much noise and you won't be able to sleep. However, it is also a superior, powerful air circulation method. As far as performance, I notice the fan's louvers (in the living space) open about halfway when the fan is on. The louvers on the whole house fan won't stay open. Using a whole house fan is a cost effective and efficient way to cool your home. Whole house fans may also be installed in walls or on rooftops for homes without an attic. Also if a whole house fan gets too slow, it won't open the louvers I think, which are just sucked open. There are also insulated caps that can be slipped over the louvers for added insulation in the winter. The motor is not the problem.
