Is AC mold causing my husband's cough?« Back to Previous Page

Based on your description, it is highly probable that the AC unit's persistent leak has created an ideal environment for mold growth, most likely the common Stachybotrys chartarum or another toxigenic species, and this is a significant contributor to your husband's respiratory symptoms. The constant moisture from the leak, combined with Dubai's high ambient humidity and the cellulose in drywall, provides the perfect conditions for rapid microbial amplification.

The symptoms you describe—persistent cough and nasal congestion—are classic indicators of exposure to mold spores and microbial volatile organic compounds (mVOCs). These contaminants become aerosolized and are circulated every time the AC unit operates, leading to prolonged exposure, especially during sleep. This is a serious indoor air quality issue that requires immediate attention.

In the UAE, the Dubai Municipality has clear guidelines on indoor air quality and building health. A situation involving a water leak and visible microbial growth is considered a contamination event that necessitates professional assessment and remediation. DIY cleaning is strongly discouraged, as improper handling can aerosolize spores and spread the contamination further throughout the property, exacerbating the health risks and the scale of the problem.

The urgency is high. We recommend you cease using that AC unit immediately and call for a professional inspection. At Saniservice, our certified mold inspectors conduct a comprehensive assessment using moisture meters, thermal imaging, and air/surface sampling to identify the full extent of the contamination, both visible and hidden within the wall cavity. Our remediation protocol follows IICRC S520 standards, involving containment, HEPA filtration, antimicrobial treatment, and proper disposal to ensure the problem is resolved at its source.
