there seems to be white steamish / smokish stuff coming out of mostly my middle AC vent. Doesnt have a smell, only comes out about 2 inches from the vent then decipitates into the air. The air is still cold, and the smoke seems to be gone for a while then it comes back, and then repeats. weird. what could it be?

 

anyone? im wiggin out over here.

 

Probably just condensation. It's probably really humid and the cold, dry air is forming condensation as it blows from the vent.
