I mounted this attic fan to the underside of the turtle vent in my attic that was easy for me to access. A few very short screws later as not to make ...
I am never home. I have to many thinks to do, hobbies, work, family, a small business we run. we all know it as life. I have the oldest A/C system in the universe. It cost to much to run and it dosent cool the house. I can leave it on all day and I will come home and find it is 84 degrees inside 73 degrees outside. So the A/C is not worth it. We pulled out the fans out of the closet. 2 in each bedroom one in the sliding glass door one in the front door (pushing in or pulling out of the window) and 4 just moving air in the condo. just attempting to bring the cool night air in to our for lack of better words Sweat Lodge. It was time for a change after having to get up in the middle of the night to shower with cool water just to fall back asleep.
We have great isolation in our attic. R40 is no joke (yes, the access pannel is insolated with R40 as well). Yet as I pushed the access to the attic up I was met with a slap in the face of 100+ degree air. This was just insult to injury. It was only 80 somthing outside and I would have thought the new roof and 6 extra turtle vents would have helped but it didn't. We will get to that in part B of this solution.
Step 2: Measure Attic Access Opening
This is important to select the proper materials for this project. My measurements where 24" x 30". The side to side is the most important. I need at least 3 inches on each side for the fan assembly to rest.
Step 3: Choosing Proper Fan For Square Footage
The math is actually quite simple. its your square footage x ceiling height. My dimentions where 800sqft x 8 foot celings. A 800 square foot house with an 8 foot high ceilings has 6,400 cubic feet of space (800 sq/ft area * 8 ft = 6,400 cubic feet). A good rule of thumb is 3 to 4 times an hour.
