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

Is the third fllor an attic unit or usable living space? Where are
the present outlets and returns? If it is working well, the cold air
from the second floor should settle down to the first floor. Is this
a new problem or has it always been this way??? Too many questions,
too little information provided.
