AC leak causing mold and child's cough: how to test and clean?« Back to Previous Page

Based on your description of an AC leak, visible black spots, and a persistent child's cough, this is a situation that requires immediate professional attention. The conditions you've described are a textbook case for mold proliferation, particularly in Dubai's climate where high humidity and constant AC use create ideal conditions for growth when a moisture source like a leak is present.

The most effective approach is a two-step process: inspection and remediation. Do not attempt to clean this yourself, as disturbing the mold can aerosolize spores and exacerbate health issues, especially for children. A certified professional will conduct a comprehensive inspection, which includes using moisture meters to identify the full extent of water intrusion, thermal imaging cameras to see behind walls, and air and surface sampling to identify the species and concentration of mold present. This is critical as some species, like Stachybotrys chartarum (black mold), are more toxigenic.

For proper remediation, the process must follow strict containment protocols. This involves sealing the area with polyethylene sheeting, using negative air pressure machines with HEPA filtration to prevent cross-contamination, the safe removal of contaminated porous materials like carpet and drywall, and the specialized cleaning of all surfaces. The final step is a post-remediation verification test to ensure the spore count in the air has returned to safe, ambient levels before the containment is removed.

Given the health symptoms involved, I strongly recommend you contact a certified professional immediately.
