Can mold from AC in Dubai cause my cough?« Back to Previous Page

Yes, the mold growing under your AC due to the leak is a very likely cause of your cough and stuffy nose. This is a common scenario in Dubai's climate, where constant AC use creates condensation, and any leak provides the persistent moisture mold needs to thrive. The symptoms you describe—worse at night and improving when you leave the environment—are classic signs of mold exposure.

The black and greenish growth you found is indicative of common household molds like Cladosporium or Aspergillus. These types are frequently identified in such situations and are known irritants that can cause upper respiratory symptoms, congestion, and coughing in otherwise healthy individuals.

For your health and to prevent structural damage, this requires immediate action. First, stop the moisture source; a certified AC technician must repair the leak. Do not attempt to clean the mold yourself, as disturbing it can release a high concentration of spores into your bedroom air. The carpet and underlying padding are likely compromised and may need to be removed and replaced by a remediation professional to prevent regrowth.

I would strongly recommend a professional mold inspection. They can assess the full extent of the growth, which often spreads further than what is visible, and provide a protocol for safe removal. In serious cases, a lab test can identify the specific species, which is useful for confirming the health link. Addressing the root cause—the leak—is the most critical step to ensure the problem does not recur.
