Musty smell from AC vents — Benidorm, Valencian Community
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.
Why this is common in Benidorm
Summer occupancy near saturation makes AC failures in July–August true emergencies in Benidorm's packed towers, and salt-laden sea air corrodes outdoor condensers mounted high on exposed façades. F-Gas certified technicians are required for refrigerant work, and high-rise installation often demands rope-access or crane lifts that add cost and lead time.
