How to stop AC leak and clean mold in closet?« Back to Previous Page

The AC in my apartment in Jumeirah seems to be leaking a bit of water into the closet where the unit is housed, and I just pulled out some winter clothes to find a few of them covered in black, dusty spots. It's been so humid lately that I'm worried the moisture is just sitting in there. What's the best way to clean this up and what can I do to the AC unit itself to stop the leak and prevent the mold from coming back?

The black, dusty spots you've described are highly indicative of mold growth, a common issue in Dubai exacerbated by our high humidity and continuous AC operation. The AC condensate drain line is likely clogged, causing the unit to leak water and create a persistent damp environment perfect for mold proliferation.

For immediate action, address the contaminated clothing by taking them to a professional dry cleaner and informing them of the mold issue. Do not attempt to wash them in your apartment, as this can spread spores. For the closet itself, surface mold on non-porous materials can be cleaned with a solution of detergent and water, but it is a temporary measure.

The root cause is the AC malfunction. You must have a certified HVAC technician service the unit to clear the clogged condensate drain line, ensure the drain pan is not cracked, and verify the unit is properly insulated to prevent condensation. This is not a simple DIY fix and is critical to preventing recurrence.

However, visible mold on surfaces often indicates a more widespread problem. Spores become airborne and can colonize other areas. I strongly recommend a professional mold inspection. Our certified inspectors use moisture meters and thermal imaging cameras to identify the full extent of moisture intrusion and hidden mold growth, which is essential for an effective remediation plan. In the UAE, remediation must adhere to strict guidelines to ensure occupant safety and prevent cross-contamination.

Given the health risks associated with black mold and the technical expertise required to resolve the AC issue permanently, contacting a professional team is the safest and most effective course of action.
