I live on the first floor of a row of 2-story apartments. Whenever anyone in my immediate area runs their air conditioner, water gushes down into my utility room and out a drain on the floor of the room. However, I see globs of something near the drain and some water still remaining on the floor that does not make it down the drain. I have had bad headaches, unusual fatigue and sinus problems lately that are not a problem when I leave home and am in another environment. Could this be a mold problem?
