Would an attic fan, of some sort, be feasible in this location?

The house has AC, and three floors, and it's insulated with the
loose stuff, at least anywhere where I can 'see' the rafters.

It's California. Northern. So, it's a pretty mild climate, but,
it's as hot as blazes in these attics, so, I was just wondering
if it's better to run the home heating system fans, or, put an
attic fan in to cool the house down, without running the A/C?

Trader's response is spot on. I use our whole house fan about 15 to 20
nights a year and AC the other more humid days. I do like it at other
times if I want to clear the air quickly from cooking or anything else.
You don't want to suck in 95 degree humid air if the house is 70
degrees from the night before. Use it wisely.
