How to inspect for dangerous mold from AC leak?« Back to Previous Page

The AC in our master bedroom has been leaking a little for a couple of months and now I've found a patch of black spots in the corner behind the wardrobe. I've been waking up with a stuffy nose and a headache that just won't go away. What's the best way to get a proper mold inspection done to see if this is the cause and if it's a dangerous type?

That black spot pattern from a persistent AC leak is a classic sign of a mold colony, and your symptoms are commonly associated with mold exposure. In Dubai's climate, where high humidity and constant AC use create ideal conditions for growth, a professional inspection is strongly recommended to assess the type and extent.

Do not disturb the area. Touching or trying to clean it yourself can release a large number of spores into the air. The best approach is a science-driven inspection that starts with a visual assessment of the leak source and the affected building materials. A credible inspector will then use tools like a moisture meter to map the full damp area behind the wall and an air quality monitor to check spore counts in your bedroom air.

The most definitive step is surface sampling of the black spots. The sample must be analyzed by an accredited microbiology lab to identify the species (e.g., Cladosporium, Aspergillus, Stachybotrys). This is critical because it determines the potential health risk and the required remediation protocol. General building knowledge isn't enough; you need data.

Look for a provider that offers this full diagnostic process and, crucially, explains how they will provide you with a detailed report of the lab findings. This evidence-based result is what allows you to make an informed decision on the necessary next steps to resolve both the leak and the contamination.
