We have a furnace that's about 2 years old now. It's in the basement which is a damp, musty place (old stone foundation that's leaking badly courtesy of the torrential downpours we've gotten this season).
As with many homes using forced air heating, ours has an air return. It is directly connected to the furnace -- the air return is a 3 foot square monster, in the floor, immediately above the furnace. For some reason though, this thing is insistent on pulling in air from the basement. To say the least, this is not fun -- it brings that musty odor and mold spores into the living area.
We're working on a solution for the basement water problems ($$$$) but I'd REALLY like to find a way to keep this thing from pulling air from down there in the interim. Suggestions?
