The duct might not go to any where useful. How about rig a
"fan on" switch for your existing furnace, to better
circulate the air?

Hi,

My central AC unit is on the 3rd floor and we get no relief
on the first
floor. The only intake is in the ceiling of the second floor
and the
HVAC specialist tells me that that's the problem. His
proposed solution
is a second AC system for the first floor.

I'm thinking: why not take one of the outlet ducts and
convert them to
an intake? Crazy enough to work?

Thanks,

Sam
