How to clean and prevent mold from AC leak?« Back to Previous Page

The black dots you're describing are highly indicative of mold growth, a common issue in Dubai's climate where high humidity and year-round AC use create ideal conditions for it. The AC condensate leak is the primary source of moisture, and this must be addressed immediately to prevent structural damage and potential health effects.

First, stop the moisture source. The AC unit's condensate drain line is likely clogged. This requires a professional HVAC technician to clear the blockage and ensure proper drainage. Do not attempt to clean the mold without resolving the leak, as it will simply return.

For cleaning small, localized growth (less than 1 sq. meter), wear an N95 mask and gloves. Carefully wipe the affected wall surface with a solution of detergent and warm water. Do not use bleach, as it does not kill mold roots and can release harmful fumes, especially in an enclosed space. After cleaning, ensure the area is thoroughly dried. Move the wardrobe away from the wall to improve air circulation.

Prevention is critical. Maintain indoor humidity levels below 60% using a dehumidifier. Ensure your AC unit is serviced quarterly to prevent future clogs and leaks. Improve ventilation in the room whenever possible.

However, mold behind furniture often indicates a larger problem than what is visible. Spores can spread through the AC system. For a proper assessment and safe, guaranteed remediation that complies with Dubai Municipality's public health standards, a professional inspection is strongly recommended. Our certified team at Saniservice uses thermal imaging to identify hidden moisture and advanced techniques like dry ice blasting to eradicate mold completely.
