I live in Colorado, and my swamp/evaporative cooler was poorly placed
in the basement of the house. Rather than using a combination of fans
and open/closed windows to get the cool air upstairs, I'm thinking of
ducting the cool air into the heating ducts, which are accessible and
close to where the swamp cooler air comes in.

Anyone have experience that would encourage or disuade me from this?
Suggestions or tips much appreciated!
