How to safely remove mold from AC leak near kids?« Back to Previous Page

The AC in our villa's master bedroom has been leaking a bit for the last couple of weeks, and now I’m seeing these black spots appearing in the corner of the ceiling where my two young kids sleep. I’ve been wiping it away but it keeps coming back, and my youngest has developed a really bad cough that won’t go away. What’s the most effective and safe way to get rid of this for good, and should I be calling a professional company or is this something I can handle myself with the right cleaner?

Based on your description, this is a serious situation that requires immediate professional attention. The recurring black spots are almost certainly active mold growth, fueled by the constant moisture from the AC leak. The fact that your youngest has developed a persistent cough is a major red flag, as this is a classic symptom of mold spore exposure, especially in children whose respiratory systems are more vulnerable.

Do not attempt to clean this yourself with standard household cleaners. Wiping it away simply disperses millions of microscopic spores into the air, which your family then breathes in. This can significantly worsen the air quality and health symptoms. In the UAE's climate, the high humidity provides the perfect condition for this mold to regrow rapidly, making DIY methods completely ineffective for a permanent solution.

The correct protocol involves several critical steps. First, the AC leak must be identified and repaired by a certified HVAC technician to eliminate the moisture source. Second, a professional mold inspection and air quality test is essential to identify the exact species of mold (some are more toxic than others) and the full extent of the contamination, which often spreads inside the ceiling void. Finally, certified remediation experts must perform the containment and removal using industrial-grade HEPA filtration and antimicrobial agents to ensure it is eradicated safely and permanently, in line with Dubai Municipality's strict health and safety guidelines.

For the safety of your children, I strongly advise you to stop disturbing the area and contact a professional environmental company immediately for an inspection.
