Can you put a rheostat on a whole house fan?
After hearing people in my area raving about whole house fans I had a 36" 6900CFM one installed in my house which is the largest I could fit in my hallway, it was purchased at Home Depot. I didn't install it nor wire it. Turning it on low, sounds as loud as a Harley Davidson idling in my house and I later found out the size of my house needed only a 1000 CFM. We can't sleep with it on, and our 2 cats get the *#$! scared out of them and run around in a panic the entire time, which usually means running over us trying to sleep.
It's a fixed pulley on a motor using a belt to drive the fan blades. The switch has a High/Low/Off. I don't know if this applies but I intercept the wires going to the motor and put in I think it's called a dual pole single throw. I did that because in winter I cover it with insulation and had a friend ask, "What's this" and flicked the switch. After that disaster I put in that switch so it can't be turned on accidentally when I have insulation over it. Does it sound like a system I can replace the High/Low/Off switch with a special fan rheostat? Thanks
