How to remove mold from AC vent in Dubai« Back to Previous Page

That location suggests condensation from your AC unit is the source. The cold air from the vent hits the warmer wall, creating moisture that mould feeds on. This is a very common issue in Dubai due to our high humidity and constant AC use.

For a small area (under one square meter), you can attempt cleaning yourself. Use a mould-specific cleaner from a hardware store, not just bleach. Bleach only removes surface colour and doesn't address the roots in porous materials like drywall. Wear an N95 mask, gloves, and safety glasses. Scrub the area, let the solution sit, then wipe dry. However, this is often a temporary fix if the moisture source isn't corrected.

The critical step is identifying and stopping the moisture. The problem is likely inadequate insulation around the AC duct or a faulty seal, allowing cold air to leak and condense. Simply cleaning the mould without fixing this will cause it to return quickly.

Given the location on the ceiling and the damp feeling, a professional assessment is strongly recommended. They can identify the exact condensation point, often with a thermal camera, and properly remediate the affected wall cavity if the mould has penetrated behind the surface. In many cases, the wall may need to be opened, insulation improved, and the AC duct resealed to prevent recurrence.

For verifiable results, choose a provider that documents the moisture source and offers post-remediation testing to confirm the mould spore count has returned to normal levels, not just a visual clean.
