What is that terrible musty/mold smell coming from my air vents? There have been numerous complaints of a bad musty/mold smell coming from the air conditioning vents. This usually occurs after the A/C has been running or after the truck has been sitting.

Musty odors can be caused by a number of things in your home, but, generally speaking, mold and mildew are the main culprits.The bad smell is caused by mold and mildew building up and releasing foul gasses.olds and mildew cause that familiar old smell because they release a gas that gets into fabric, carpet, curtains and furniture.
