Is AC leak causing black mold and my husband's cough?« Back to Previous Page

Yes, the AC leak is almost certainly causing the black mold, and your husband's persistent cough and headaches are very likely connected. The continuous moisture from the leak creates the perfect environment for mold growth in Dubai's high humidity, even indoors. The black patch you see is the colony, but it releases microscopic spores into your air that can cause those exact respiratory symptoms and headaches.

In Dubai, this requires a professional approach to be safe and effective. Simply wiping the visible mold away is insufficient and can aerosolize more spores. The proper remediation process involves containing the area, using HEPA filtration to clean the air, safely removing the contaminated materials (like a section of drywall), and addressing the root cause—the AC leak. The unit's drain line is most commonly blocked and needs a thorough clean.

For your health and to ensure the job is done correctly, I recommend a certified mold inspection. They can identify the species and the full extent of the growth, which often spreads behind walls. Look for a provider that offers before-and-after testing from an accredited lab to verify the air quality is safe post-remediation. This is the standard for ensuring the problem is resolved and not just concealed.
