Is black mold from AC leak dangerous, need professional?« Back to Previous Page

Black mold from an AC leak is a legitimate health concern, especially in Dubai's climate where constant AC use and high humidity create ideal conditions for growth. The scratchy throat you're experiencing is a common reaction to mold spores, which can also cause congestion, coughing, and worsened allergy symptoms.

For a small, visible patch, you can clean it yourself if you are healthy. Wear an N95 mask, gloves, and safety glasses. Scrub the area with a mixture of detergent and water, then disinfect with a diluted bleach solution. However, this only addresses the surface. The real issue is the moisture source—the leaking AC unit. Until that is repaired by a certified HVAC technician, the mold will return.

Given the leak has been ongoing for weeks, the mold growth behind the sofa is likely more extensive than what is visible. It can penetrate drywall and insulation. For anything beyond a very small, surface-level patch, a professional inspection is strongly recommended. They use moisture meters and thermal cameras to find hidden dampness and can take samples for lab analysis to identify the mold species, which determines the appropriate remediation protocol.

The fastest, safest way to resolve this is to call an HVAC technician to fix the leak immediately, followed by a mold assessment to determine the full extent of contamination and the required remediation steps.
