AC leak causing mold anf toddler illness in Dubai??« Back to Previous Page

Yes, an AC leak causing visible mold and toddler illness is a common and serious concern in Dubai's climate. The high humidity and constant AC use create ideal conditions for mold growth behind walls and in ductwork when moisture is present. The black spots behind your curtain are likely just the visible portion of a larger colony growing from the sustained moisture of the leak.

Your toddler's persistent respiratory symptoms are a significant red flag, as children are far more vulnerable to mold exposure. In many similar cases, symptoms like a chronic cough and runny nose do resolve after proper remediation, but the timeline depends on the extent of the contamination and the child's sensitivity. Improvement is often seen within a few weeks after the source is completely removed and the air quality is restored.

This requires immediate professional attention. Do not attempt to clean it yourself with bleach, as this can aerosolize spores and worsen the problem. A proper inspection should include a moisture meter check of the wall and potentially air or surface sampling to identify the mold species. The remediation process must address the root cause—fixing the AC leak—before containing, removing, and properly disposing of the contaminated materials. For a case involving a child's health, I would strongly recommend a company that provides before-and-after lab testing to verify the spore count has returned to a safe level.
