I am remodeling and am at the phase to deal with the utility/mud room. The utility will have washer/dryer with a pocket door separating it from the mudroom. The utility room will be about 10' x 8', the mudroom area will be about 10' x 12'. Contractor says we have the capacity to run duct there. However, the cat box will be there so I would rather not return that air. If I just run supply with no return what sort of problems are there to consider?
Any options you guys can comment on will be appreciated. And no, getting rid of the cats is not an option : )
