AC leak causing black mold and baby's cough in Dubai?« Back to Previous Page

The black speckles and persistent cough are absolutely connected and require immediate action. That leak has created the perfect environment for mold growth in Dubai's high humidity, and the AC is now aerosolizing spores directly into the bedroom air.

Your fastest and most reliable path is a two-step professional process. First, schedule an inspection and air/swap test with a company that has its own microbiology lab, as this provides species identification and spore count data you can verify. This is critical to confirm it's not the more hazardous Stachybotrys (toxic black mold) and to document the contamination level. In Dubai, any company worth hiring should be able to provide this documented evidence, not just a visual assessment.

For remediation, ensure they follow a containment protocol—sealing the area with plastic sheeting and using negative air pressure—to prevent spreading spores during cleanup. They should physically remove the moldy drywall, treat the cavity with an antimicrobial, and address the root cause: repairing the AC drain line leak. Simply spraying a biocide is insufficient and a common tactic of less reputable services.

Until professionals arrive, keep the bedroom door closed, the AC unit turned off, and the window open if air quality outside permits. This helps isolate the affected area and reduce further exposure. Your vigilance is warranted; addressing the source of the moisture and the biological contamination is the only way to resolve the health concern for your family.
