I had a whole house fan growing up in NJ and it kicks total ass. I am surprised that we don't see more of these, but I suppose more people are opting for A/C instead. Depending on the humidity where you live you may not need A/C (Or want to pay for it). These fans can change everything and they are really cheap compared to the cooling they will bring.
Don't worry about when it is hot outside. The moving air will be cool and work either way. The thing is with these fans, is you really may not need to run them full time. If you have the fan on a timer that goes to say 1 hour, that would do the trick. You turn this sucker on and in a few minutes the whole house is vented. If you want to target a specific area, close some windows and doors at the top level and open them up downstairs. That is a nice effect.
