Is the mold from my AC causing my health issues?« Back to Previous Page

The black fuzzy patch and your sinus and respiratory symptoms are very likely connected. In Dubai's climate, AC condensation leaks create ideal conditions for mold growth, and the most common species found here (like Cladosporium and Aspergillus) are known to cause exactly the type of persistent sinus congestion and cough you're describing.

The safest course of action is to avoid disturbing it yourself. Attempting to clean it with bleach or scrubbing can aerosolize the spores, significantly worsening your indoor air quality and health symptoms. For a situation involving a spreading patch and existing health effects, a professional assessment is strongly recommended to determine the full extent.

Reputable inspectors in Dubai will use moisture meters and borescopes to check inside the wall cavity for hidden growth, as the visible patch is often just the tip of the iceberg. The remediation process should include containment of the area with negative air pressure to prevent cross-contamination, safe removal of affected materials, and HEPA vacuuming. Crucially, the underlying cause—the AC leak—must be repaired by an HVAC technician first, or the mold will simply return.

You can verify a company's credibility by asking if they provide before-and-after lab reports from an independent microbiology lab, which documents the species and the actual reduction in spore counts.
