Musty smell from AC vents — Warsaw, Masovian
A musty or mildew smell blowing from AC vents usually signals mold or bacteria growing inside the HVAC system — on the evaporator coil, in the drain pan, within ductwork, or on a clogged air filter. Beyond being unpleasant, airborne mold spores can aggravate allergies, asthma, and respiratory conditions. An HVAC technician can inspect the system, clean the evaporator coil and drain pan, treat ductwork, and identify root causes like poor drainage or inadequate dehumidification.
