I have a forced-air vent in my closet (old house, poor Reno in the past) and I always keep my closet door open so that vent can heat/cool my bedroom effectively. If I close the closet door, it of course gets very warm/cool in there. The closet is small, about 2' x 5'.
I'm wondering - if I cut and install a vent in the door, will that create enough passive airflow for me to keep the closet door closed but allow that vent to heat/cool the bedroom? #diy source
