Yesterday I installed a “Whisper Aire” whole house fan. Is it quieter than other whole house fans that I have seen in operation? Absolutely. But it is by no means a whisper. I installed it right outside of my bedroom door, I had no choice. It was the only location that would work. Surprisingly, it isn’t any louder in my room on the lowest of its five speeds as it is on the highest.
So why am I so seemingly disgruntled? I spent hours in my attic rerouting an electrical line that was in the way, cutting a hole in the ceiling, adding framing to support the fan, etc etc. I’m still not done. I have to put in new insulation. On top of that, I ran the fan almost all night last night and the house didn’t get any cooler than it gets when I put a fan in the front door. I’m hoping that it is becaues I ran it on its lowest speed (about 1200 CFM of air). Tonight I will run it at full speed (2200 CFM of air) in hopes that I can get my home as cool as the outside world.
My local utilities company actually recommends that I install a 3600 CFM fan but that would have required cutting ceiling joists. Plus the fan I bought comes with an insulated door which is rather handy since it is almost impossible to get to the location that the fan is installed.
I will keep you all up to date (which wouldn’t likely be anyone).
I would like to know if it is saving you money/paying for itself.
