my house is one level, on a concrete slab, open floor plan (big open room, few doors), forced air heating/cooling (i believe). house inspector said i needed to have cold air returns. my furnace is located in a utility room with a completely slatted door.
could someone explain why i would have to have returns? (to me all the cold air gets sucked back up through where the air filter is).
thanks
