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.
The musty smell of mold comes from the microbial volatile organic compounds (MVOC) it produces. Some of these gases have a strong musty odor, which is released into the home when mold grows. Mold can be in the floors, walls, ceiling and in heating or ventilation systems.
