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

Based on the situation you've described, you are dealing with a classic case of mold growth caused by a persistent AC condensate leak. The black spots are likely Cladosporium or Stachybotrys (black mold), which thrive in the dark, humid environment created by the leak. This is a very common issue in Dubai due to our high year-round humidity and constant AC operation, which generates significant condensate.

Immediate Cleaning Action: For small, visible spots on hard surfaces like the wall, a solution of diluted detergent (not bleach, as it doesn't kill the roots and can damage surfaces) can be used for wiping. However, for porous materials like your stored clothes, professional cleaning is strongly advised. Mold roots (hyphae) penetrate deep into fibers, and home washing often fails to remove the contamination, leading to ongoing musty odors and potential health effects.

The Critical Step – Fixing the Source: Simply cleaning the visible mold is a temporary fix. Per UAE health and safety regulations, the root cause—the water intrusion—must be permanently resolved to prevent recurrence and ensure a healthy indoor environment. The AC leak could be due to a clogged condensate drain line, a damaged drain pan, or incorrect unit leveling. This repair must be conducted by a certified HVAC technician. Do not attempt this yourself, as improper handling can worsen the leak or damage the expensive unit.

Given that the mold has already spread to belongings, we recommend a professional assessment. Our certified mold inspectors at Saniservice can conduct a thorough investigation using moisture meters and thermal imaging to map the full extent of the moisture and hidden growth behind the wall, which is often more severe than what is visible. We can then provide a hygienization protocol to safely remediate the affected areas and contents.
