I’d rate the installation as moderately difficult only because the whole house fan I purchased had a blade diameter of 30 inches. You must have JavaScript enabled in your browser to utilize the functionality of this website. The Cool Attic 36" Belt Drive 2-Speed Whole House Fan is designed for houses with attics over 3,200 sq. Dual, self-aligning ball bearing mechanisms and a precision-balanced 4-blade aluminum fan assembly contribute to quiet, reliable performance and longevity. A whole house fan is (usually) mounted in the ceiling of an upstairs hallway with the output blowing into the attic. The ShutterCover Trim to Fit manufacturer contacted me with some information about his product and I decided that it is worth to mention it on my website. Installing the whole house fan ShutterCover appears to be an easy task to perform and a valuable item to put on your house maintenance schedule list. Despite the fact that whole house fans use significantly smaller amounts of energy than air conditioners, the entire assembly provides very little insulating value.
During the warmer months, whenever air conditioning is running, or even without the system operating, the whole house fan shutters become very hot.
Touch the whole house fan shutter surface (assuming that there is no insulating cover installed in your attic) during the summer and during the winter. Look at it this way – what’s going to happen when you open your window during the winter, or while operating an AC on a hot day? An unprotected whole house fan shutter is the same as that – an open window into the attic.
It is made of ?-inch thick, Low-E reflective foil insulation.  This type of insulation adds significant energy savings by stopping up to 97% of radiant heat transfer. To fulfill your aesthetic expectations, one side of the Shuttercover™ has a white coating that blends in perfectly with the surrounding ceiling.


The square piece of insulation can be easily trimmed to fit any whole house fan shutter size up to 48 inches by 48 inches. A trimmed-to-fit Shuttercover™ section attaches to the whole house fan shutters frame with a self-adhesive Velcro tape. However, I’d still highly recommend to examine your attic periodically, or have someone do it for you. Without some type of a cover installed over the whole house fan, this area will always have a “micro-climate” – hotter or cooler than the rest of the house, affecting the thermostat directly and resulting in a false activation of the system.
This was our alternative solution to an air conditioning unit that costs quite a bit to install ($3,000) and over the long run will use a lot less electricity each month. This meant I had to cut a ceiling rafter and re-frame the opening (ceiling rafters are separated by 24 inches on center).
Bottom line is, air that is being pulled from the house must also be pushed out through the attic vents, such as soffit, gable or ridge vents.
I put mine at the top of my stairs in the center of my house such that it’s about the same distance from each window. The reason being, the direct drive motors have to spin faster (rpm) than a belt and pulley system. I was worried that it would create a horrible cold air draft in the winter, but that doesn’t seem to be the case. I still highly recommend this solution, but it sometimes requires a lot of effort, and for many home owners, it might not be even possible to implement. During the cold months, while you are heating your home, the whole house fan shutters allow the heated air to escape into the attic, which sometimes results in condensation and attic black mold growth.
For every proud whole house fan homeowner, they are just increasing the energy usage and cost. Here in Colorado Springs, it really doesn’t get all that hot and simply exchanging the inside air with outside air can make the house feel a whole lot cooler.


We run it mostly in the evening or at night when the air outside is cooler than the inside. It offers an efficient way to reduce cooling costs by pulling fresh air in from the outside, expelling the warm air up into the attic, and pushing it out through your attic exhaust vents. Granted, it won’t be as cool as an air conditioning unit, but it will make a big difference.
If you purchase a fan with a diameter less than 24 inches, chances are it will fit snugly between the rafters and you won’t have to cut one.
Calculate the square inch opening for the whole house fan, and make sure you have at least that much area in attic vents as well. But even if it’s slightly warmer outside than inside, the moving air makes the house a whole lot more comfortable. I also installed louvers that open when the fan turns on and automatically close when the fan turns off. Some people will lay the larger fans atop the rafters, but this isn’t advisable as it can cause a buffeting sound. There was a small amount of adjusting that needed to be performed on the spring to help the louvers open when the fan turns on.
If you don’t adjust it right, the louvers might not close when the fan turns off, or they may not open all the way when the fan turns on.
