Is my AC causing black mold and making me sick?« Back to Previous Page

The black speckled patches you describe are very likely mold, and your symptoms are a common reaction. Dubai's high humidity and constant AC use create ideal conditions for mold when condensation or leaks occur. The AC itself isn't causing the mold; the leak is providing the moisture that allows existing mold spores in the air to grow.

Your symptoms—stuffy head and sore throat that improve when you leave the room—strongly suggest the mold is the irritant. Mold releases microscopic spores and volatile organic compounds that can cause inflammation in the respiratory tract, especially during prolonged exposure like sleeping.

For a confirmed diagnosis, a professional inspection is needed. The term "black mold" is often used for Stachybotrys, which requires prolonged moisture to grow, but many other black-colored species like Cladosporium or Aspergillus are more common and can cause similar symptoms. Only lab analysis can identify the specific type.

Immediately address the AC leak—this is the source of the moisture. The wall behind the wardrobe will need remediation. Simply wiping visible mold is insufficient, as the colony's roots (hyphae) penetrate porous surfaces like drywall. In many cases, the affected section of wall must be carefully removed and replaced after the area is fully dried. A professional assessment will determine the extent of the damage and the required containment procedures to prevent spreading spores during cleanup.
