My parents have one, but it is unbelievably loud. If we had one I would be worried about not hearing our young son wake up if it was on. I wonder if newer models of attic fans are quieter? Theirs was from the mid-80s after all.

Kevin --

We just run ours for 15-20 minutes before we all go to bed -- not throughout the night -- and you could do the same. It would certainly save over having your AC do all the work.

They are loud (they have to be powerful enough to suck air all through the house and out again), but I do believe the newer models are quieter than older ones (ours is 20 years old, so it's probably as loud as the one you're talking about.)

These are only actually good for cooler regions. Where I live in Texas it's still 80 degrees at can only escape the need for AC for a few months out of the year.

Attic fan: Good for some regions, bad for others.

I remember my grandparents had one in their house when I was growing up and swore by it. I've considered this in the year that I've lived in our new house, but I was wondering what the costs were, as well as what it looks like. I would assume it should go in a central hallway, so you don't want something ugly looking, as that could come back to haunt you later.

FMF, you're in Michigan aren't you? How does having an attic fan work with the winters there? I'd imagine that you wouldn't want a huge heat leak in your attic during the colder months.

If you're attic is insulated properly it shouldn't be heated in the winter.

Richard --

Yes, I'm in Michigan. The fan has slats that cover it from the inside of the house. Inside the attic, it is insulated around the fan so that any air flow from the attic to the home is minimized. Walking under it in the winter I've never felt any sort of cold or draft.

We live in a 110 year old two story Victorian. We installed ours in at the top of the foyer stairs when we bought the house 12 years ago. It's right outside our bedroom door.

It is loud, but it works well. We live in Iowa and we've only had the A/C (window unit that cools the downstairs) on twice this summer.

It sits in a frame box that is insulated around the edges. In the winter I cover it with about a foot of fiberglass insulation.

I think it cost about $300 12 years ago to purchase and have installed.
