you CERTAIN one doesnt gpo down somewhere to feed the furnace?

What kinda of heat do you have? If its forced air theres a return
somewhere/

They can use a wall cavaity for getting the air back to the basement


Positive. The gas furnace return vents are in the floor of the hallway and
the basement main room.

I know it sounds weird, but I mapped it today and they do not go anywhere.
