I was reading a website once dealing with heatpumps and energy type stuff to
do with house environment conditioning and I came across something which
matched my needs and I do not know what this type of unit is called, and I'd
like to research them now that I had to cut a hole in my top floor ceiling
to drive away some squirrels.

It was a fan with a tight round shroud which is enclosed within a
rectangular box frame which you install in the ceiling drywall on the top
floor of a house where the heat gets too great in the summer. You open the
inside winter flap and turn on the fan and it creates a vacuum which forces
the air up into the attic and out through the vents in the roof.

I have already installed a ceiling fan in the area I want to install it in
and it did nothing, so I need to try the big guns. Now the squirrels have
left, anybody got any idea what I'm talking about. A name is a good start,
as would be any info source. I also have to be concerned about whether or
not I have sufficient vents on the roof to accommodate such a pump.

Like wholehousefan.com; ah, thank you, Before you go too far, do you think
I'd need extra exhaust vents on the roof. Its on a recent top floor
addition not original to the house. I am unlikely to patch the hole in the
drywall now, but am equally unlikely to solve the answer to this question
myself, but I don't know if this could be a(nother) disaster.

Whole house fans move a _lot_ of air. The manufacturers' web sites or
technical support help line will provide the specifics.

ya, and these are expensive. Ducting, motorization, remote control. I hope
I can get one from the BORG for a fraction and do the opening, closing,
housings myself - for just the 2 upper floor (small) bedrooms, where I'll
put it right at the top of 9 stairs- I think I have 2 roof vents up there.
any pointers?
