AC mold causing illness: clean unit or remove mold first?« Back to Previous Page

Start with a professional AC inspection and cleaning. In Dubai's climate, the AC unit is often the primary source of mold growth due to constant condensation. The black specks around the vent are likely just the visible deposit from mold actively growing inside the ductwork or on the cooling coils.

Cleaning the unit and ducts first is critical because it stops the ongoing spread of spores. Simply wiping the visible mold off the wall will provide temporary relief, but the problem will recur within weeks as the AC continues to blast contaminated air. A thorough cleaning should address the evaporator coils, drip pan, and interior duct surfaces.

Given the described health symptoms—stuffy nose and headaches—a post-remediation verification test is strongly advised. This involves air or surface sampling to confirm the spore count in your living space has returned to a normal level, ensuring the cleaning was effective and the health risk has been mitigated.

For a multi-unit apartment in Jumeirah, coordinate with your building management regarding the central chiller system, but the internal fan coil unit (FCU) within your apartment is your responsibility to maintain. The combination of high humidity and cold surfaces creates a perfect environment for mold, making this a common issue that requires a systematic approach to resolve permanently.
