Are AC leaks and black mold causing my headaches?« Back to Previous Page

Yes, AC leaks and the resulting mold growth are a very likely cause of your persistent headaches and congestion. The constant dampness from a leak creates an ideal environment for mold, particularly in Dubai's climate where high humidity prevents it from drying naturally. The black spots behind the wardrobe are a clear indicator of a moisture problem.

The symptoms you describe—morning headaches, stuffy nose—are classic reactions to mold exposure, often caused by the release of microbial volatile organic compounds (mVOCs) and spores into the air you breathe while sleeping.

Your first step is to address the source of the moisture immediately. Have a certified HVAC technician repair the AC leak; this is non-negotiable. For the visible mold, avoid disturbing it yourself as this can aerosolize spores. A professional inspection is strongly recommended to assess the extent of growth, especially within the wall cavity, which is common with AC condensate leaks. They can take surface and air samples for lab analysis to identify the mold species, which determines the appropriate remediation protocol. Proper remediation involves containment, removal of contaminated porous materials like drywall, and HEPA filtration cleaning, not just surface wiping.

Until it's resolved, improve ventilation in the room and consider using a dehumidifier to help lower humidity levels.
