I open the door that contains the furnace filter this grabs the cool air
from downstairs and pushes it upstairs, most days we don't even need to run
the air just the furnace blower.

When the AC is being used, my basement tends to get about 5 degrees
cooler than the first floor. The basement is used for laundry, storage
and my workshop, so it doesn't need to be that cold.

Here's my idea: Cut a hole in my return trunk, near the floor, to
recapture the cooler air and send it back upstairs. I'd install a
filter and design it so it could be easily sealed up in the winter.

So, if this isn't a ridiculously bad idea, how would I go about
determining the correct size for the opening?
