AC leak causing black mold and illness: urgent action needed?« Back to Previous Page

The black spots are very likely Stachybotrys chartarum (toxic black mold) or Aspergillus niger, both common in Dubai due to high humidity and AC condensation. Your symptoms—persistent stuffy nose and headaches—are consistent with mold exposure and indicate it's affecting your indoor air quality.

You need to act on both issues simultaneously. Inform your landlord in writing about the AC leak and visible mold growth immediately. Under Dubai rental regulations, the landlord is typically responsible for fixing the AC unit and the damage it causes. However, do not wait for them to act on the mold itself.

For any visible mold spread, especially with health symptoms, a professional inspection is urgent. DIY cleaning is not advised here, as disturbing the mold can release more spores into the air you breathe. A proper assessment involves identifying the moisture source (the leak), containing the area, and safely removing the contaminated materials.

The priority is to stop the moisture source. A remediation company can handle the wall, but if the AC isn't fixed, the mold will return. A reputable provider will use lab analysis to confirm the mold type and provide post-remediation verification to ensure it's been resolved, which is crucial for your health and for documenting the issue with your landlord.
