Is black mold from AC dangerous to breathe?« Back to Previous Page

The AC in my apartment seems to be blowing out a faint, damp smell, and I've just discovered what looks like black spots along the edges of the ceiling in our master bedroom closet. We noticed it starting maybe a week or two after that heavy dew last month, but it's getting more noticeable. With the humidity creeping up again, how urgent is it that I get this professionally treated, and could it be affecting the air we're breathing?
