How to professionally clean mold in AC duct in Dubai?« Back to Previous Page

Black mold in AC ducts requires professional remediation due to the risk of spores spreading. In Dubai's high humidity, this is a common issue that DIY cleaning cannot fully resolve, as it often addresses only visible growth and not the root moisture problem.

Your first step is to document the issue. Take clear, date-stamped photos and videos of the mold growth inside the duct. This visual evidence is crucial for communicating with your landlord. Under typical Dubai tenancy contracts, landlords are responsible for maintaining the central AC system, including the ducts, as it is a fixed installation.

Formally notify your landlord in writing (email is best), attaching the evidence and politely requesting immediate professional remediation due to health concerns. If they are unresponsive, you can reference Dubai Municipality's public health and housing standards, which require landlords to provide habitable premises free of health hazards like mold.

For the cleaning itself, look for a provider specializing in duct cleaning and mold remediation, not a general handyman. A proper process involves containment of the work area with negative air pressure to prevent cross-contamination, HEPA vacuuming of all surfaces, and antimicrobial treatment. The most critical part is a diagnostic inspection to identify the source of the moisture—often a clogged condensate drain line or inadequate insulation—and correct it to prevent immediate recurrence. After cleaning, request a post-remediation verification, which can be a visual inspection or air quality test, to confirm the issue is resolved.
