Could black mold from AC leak cause our constant cough?« Back to Previous Page

Yes, the black mold from your AC leak is very likely causing those persistent cold-like symptoms and headaches. In Dubai's humid climate, mold thrives on the constant condensation from AC units, and the mycotoxins and spores released by certain black molds (like Stachybotrys) are known respiratory irritants.

Given the size of the infestation you've described and that you've been sleeping next to it, professional remediation is strongly advised. The first step is to stop the moisture source—have an AC technician repair the leak immediately. Do not attempt to clean large patches yourself, as improper scrubbing can aerosolize a high concentration of spores throughout your apartment, significantly worsening the air quality and your symptoms.

For a case of this severity, the Dubai Municipality's guidelines and best practices call for containment of the affected area, professional HEPA-filtered air scrubbing, and safe removal of contaminated porous materials like drywall or insulation. Once remediated, a post-clearance test from an independent microbiology lab is the only way to verify the spore count in the air has returned to a safe, background level. This documented proof is crucial for your family's health and for your landlord, as it may be needed to address any tenancy issues related to the property's condition.
