Why does the air from my vents smell musty from the air conditioner?
A musty smell in an air conditioner occurs when the collection of water does not completely evaporate. The musty smell comes from mold that grows in damp areas.Mold OdorsMold odors form from microbial volatile organic compounds, or MVOCs, wherever water is allowed to gather on moisture-containing organic materials like wood, paper or cotton.Mold Formation in Air ConditionersAir conditioners have a drip pan to catch any water caused by condensation. If all of the water does not evaporate, the water sits stagnant in the pan.Activating the MoldAs the water sits in the pan with the unit off, there will be no musty smell.
