Black mold above AC vent in Dubai: who to call first?« Back to Previous Page

Call building management first. In Dubai apartments, the responsibility for fixing the AC condensation drain line—which is almost certainly the source of the moisture—typically falls on the building owner. The black spots spreading from the vent are a classic sign of a clogged drain pan or pipe causing excess humidity and mold growth.

While you wait for management, wipe the visible area with a diluted white vinegar solution to prevent further spread, but avoid bleach as it can set the stain and doesn't address the root cause. Keep the room well-ventilated.

If building management is unresponsive or the issue returns after their repair, then engage a specialized mold inspection company. The Dubai climate means AC units run year-round, and a persistent leak will continue to cause problems. A professional can use a borescope to inspect the internal ductwork for hidden growth and perform air quality testing to confirm the mold type and spore count after the leak is fixed. This step is crucial to ensure the damp feeling and health risks are fully resolved.
