Hi,

We need to install a radon mitigation system. We have a few options for where to place the fan and pipe outside. Option 1 is on the side of the house which is visible from the street. Option 2, and my preference, is on the back wall of the house where it will only be visible if you are in the back yard. My concern though is that the fan would be near the windows of the first floor master BR. Are these fans loud enough to be heard through the windows? I wouldn't want to hear this thing all night.

Thx, Don
