Musty smell from AC vents — Alicante, 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.
Waarom dit veel voorkomt in Alicante
Alicante's extreme summer heat (regularly 38–42°C) makes air conditioning essential rather than optional, and HVAC systems work at maximum capacity for 3–4 months of the year. High UV exposure accelerates deterioration of outdoor condenser units and their mounts. Many older properties rely on individual split units rather than centralized systems, increasing maintenance complexity.
