Did I just dodge an expensive bullet?

2. Thanks for your reply.

I retired to the Midwest for affordability, and the climate here at 850' above sea level gives us the same gardening zone as southern Maine - 5B. I don't usually need even the whole house attic fan until mid-June or so, sometimes almost July. But every August it gets brutally hot and I'm forced to use the AC 24/7 for several weeks at least. I'd still be considering a powered attic ventilator IF and when I might be able to afford something with a convenient off switch for AC season.

But if I can't turn it off and must turn on the AC, it sounds as if the powered attic ventilator might actually cost me MORE $ then. That's the only time I'm concerned about and is the main focus of my question.

Rest assured I use every passive means possible before resorting to energy use. Not only did I have larger openings made at the soffits, the new heavy duty metal roof I had installed has a vent ridge too; or ridge vent, I'm not quite sure... Except I am certain that even a solar powered attic ventilator with a shut off for AC times will have to wait quite awhile longer before I can pony up the dough.
