How to treat and prevent AC mold in Dubai apartment?« Back to Previous Page

The black speckles are likely mold growth, a common issue in Dubai due to high humidity and AC condensation. Your first step is to stop the moisture source. Wipe the AC unit's drip pan and check that the condensate drain line is not clogged; a simple vinegar flush can often clear it.

For the mold on the wall, wear an N95 mask and gloves. Wipe the affected area with a solution of diluted detergent or a dedicated mold cleaner, then dry it thoroughly with a fan. Do not attempt to scrub it if the area is larger than one square meter, as this can aerosolize spores.

Preventing recurrence requires controlling humidity. Ensure your AC is set to a temperature that reduces condensation, typically between 22-24°C. Run the AC's dry mode if available, and use a dehumidifier in the bedroom. Improve air circulation by periodically moving the headboard away from the wall.

For a persistent leak or if the mold returns quickly, the internal AC coil may be contaminated and require professional deep cleaning. In many cases, a lab test is the only way to confirm the mold type and ensure the remediation was effective, particularly if occupants experience allergies or respiratory issues. The Dubai Municipality recommends regular AC maintenance to prevent such biological growth.
