AC mold causing stuffy nose: urgent professional cleaning needed?« Back to Previous Page

That leak and the black patch indicate active mold growth, which is likely the cause of your stuffy nose. In Dubai's climate, this is urgent; the constant high humidity and condensation from AC units create a self-sustaining environment for mold to spread quickly behind walls and under carpets.

For a small, visible patch (under one square foot), you can attempt to clean it yourself, but avoid bleach. It's mostly water and can actually feed mold deeper in porous materials. Instead, use a dedicated EPA-approved fungicide or a solution of distilled white vinegar and water. Scrub the area, let it dry completely, and fix the AC leak immediately.

However, because the leak has been ongoing for weeks and the mold is on a baseboard (a porous material), there is a high probability of hidden growth inside the wall cavity or under the carpet padding. This is where DIY fails. A professional inspection with a borescope can assess the extent of the damage without destructive tearing. They can also perform air quality testing to identify spore types and concentrations, which is crucial if symptoms persist.

Given your reaction, it's advisable to get a professional assessment. The Dubai Municipality has clear guidelines on indoor air quality, and improper remediation can exacerbate spore release. A certified company will contain the area, remove contaminated porous materials like damaged drywall or carpet, and use HEPA filtration to clean the air, ensuring the problem is resolved at its source.
