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.
A musty smell in a home is a result of inadequate cleaning, poor or stagnant air circulation, high humidity and possible moisture problems. If you've ever noticed an odd smell coming from old furniture, clothing or books, or in a poorly ventilated area such as the attic or basement, you have a problem with mold, mildew or fungi.
