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.
Another sign of hidden mold is a moldy smell. If the smell is worse in certain rooms then the mold is probably growing near that area. If the mold smell gets worse when the air conditioning or heating is on then there could be a mold problem in the HVAC, or in your air conditioner or heater.
