Could AC mold be causing our headaches and stuffy nose?« Back to Previous Page

Yes, the black patches are very likely mold and your symptoms are a common reaction. The persistent dampness from your AC leak creates an ideal breeding ground, especially in Dubai's high humidity which accelerates growth even indoors. The musty smell and airborne spores from that growth are known irritants, frequently causing the exact sinus congestion and headaches you describe.

For a situation this advanced—with visible growth and persistent symptoms—a professional inspection is strongly advised. They will identify the mold species and the full extent of the problem, which often spreads behind walls. In Dubai, remediation must address the source (fixing the AC condensate leak permanently) and safely remove the contaminated materials.

Until it's resolved, improve ventilation in the room as much as possible and consider using a dehumidifier. Avoid disturbing the patches, as this can release more spores. Confirming the type through a lab test can provide clarity on the health risks specific to your home.
