This fan is a good fan but does not move the amount of air I want to move.  I usually put a fan at one end of the house then open my bedroom window and have the fan pull in cool air at night.  this somewhat does the  job but really not enough.  I might be asking for too much for its size etc.  I like the fact that it is reversable and it is adjustable to fit wide or narrow windows.  If you are using it for one room this is a good fan but not great for the whole house (I have a small house 1500 sq ft).  I'd give it a try and see if it works for you.
