Hi,

I would like to purchase a window fan for one of two windows (24" x 24"
or 35" w x 21" h) but have been surprised by the poor quality of fans I
see in stores. Can anyone recommend a model with perhaps three speeds
and of build that will last more than a few years?

We will use the fan to help cool a small 1100 sq ft house off in the
summer after the sun has gone down (we are in southern California).

Steve
