How to test for toxic mold from AC leak in Dubai?« Back to Previous Page

Stop using the AC in that room immediately and address the water leak first; the moisture source must be eliminated. The black spots and respiratory symptoms are strong indicators of a mould issue, which is common here due to our high humidity and constant AC use creating condensation.

For proper testing, do not use DIY store-bought kits—they are notoriously unreliable. You need a professional inspection that includes air and surface sampling. The inspector should take samples from the affected wall, the carpet under the leak, and the indoor air, then send them to an accredited microbiology lab for analysis. This is the only way to accurately identify the mould species (like Stachybotrys, often called "toxic black mould") and its concentration, which determines the health risk and required remediation scope.

In Dubai, look for a company that follows international standards like the IICRC S520 and can provide a detailed lab report. The Dubai Municipality has guidelines for indoor air quality, and a proper assessment will benchmark against these. The initial inspection and testing should clearly define the contaminated areas and the specific protocol needed to fix it safely.
