Will cutting holes in the a/c ducting...?
My dad thinks that because we have spray foam insulation in our attic that it would be cost affective to cool our attic. He wants me to climb up in the attic with him and cut some holes in the ducting to cool our attic, which (he thinks) will in turn cool our house. Our attic dosn't have a thermostat. Can someone send me a link?

He is going to make a big mistake. The roof isn't insulated, just the ceiling. And attic should be vented. So all the cool air is going to go outside. I guarantee the unit isn't big enough to cool outside and the house. Also the cold air and hot air mixing could cause condensation and possible water damage.

Bad idea. If you want to cool the attic install attic gravity ventilators, the ball-looking things that spin in the breeze. Cutting holes in your AC ductwork will waste the cold air to your house and will be an insignificant source of cooling to the attic.

Really bad idea.
True, a hot attic effects the house but a cheaper, more efficient way is to install a gable fan. You probably have a louvered vent somewhere in your attic. They make fans that fit those to move air through your attic Home Depot and Lowes carries them.

NO!! For crying out loud do not cut holes up there. That will only slow the air at the vents in the house. Install some air vents in the roof, that will drop the temp. up there and will make a huge diff. in the house temp.

You will be wasting money and energy. If no one lives up there, why cool it. It will not offset cooling costs in the rooms below, and could cause moisture and mold.
