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

The black spots you're seeing are a classic indicator of mold growth, specifically Stachybotrys chartarum or another melanin-producing species, fueled by the AC condensate leak. This is a common issue in Dubai due to the high ambient humidity and year-round AC operation, which creates persistent condensation problems. The most effective approach is a two-part solution: address the moisture source, then remediate the biological contamination.

First, the AC leak must be professionally diagnosed and repaired. The primary causes are typically a blocked condensate drain line, a damaged drain pan, or insufficient insulation on the cold refrigerant lines causing excessive sweating. Simply wiping the mold is a temporary fix; without stopping the moisture, it will return rapidly.

For the mold itself, small, localized growth (less than 1 square meter) can be carefully cleaned by a homeowner wearing appropriate PPE (N95 mask, gloves). Use a detergent solution, not bleach, to scrub the affected wall surface. However, given the porous nature of drywall and the potential for hidden growth inside the closet and wall cavity, a professional inspection is strongly advised. We use moisture meters and borescopes to assess the full extent.

For a permanent solution and to ensure the environment is safe, especially given the potential health risks of black mold, I recommend a professional assessment. Our certified team at Saniservice can identify the exact cause of the AC leak, perform mold testing to identify the species, and execute a full remediation protocol that includes containment, air scrubbing, and antimicrobial treatment to ensure it does not recur.
