Is black mold from AC leak causing our coughing?« Back to Previous Page

The black mold from your AC leak is very likely causing the persistent coughing, fatigue, and congestion in your family. In Dubai's humid climate, AC condensation leaks behind furniture are a primary cause of indoor mold growth, creating the damp, stagnant conditions it needs to thrive.

While the term "black mold" is often associated with the species Stachybotrys, which can produce mycotoxins, many common black-colored molds like Cladosporium or Aspergillus can also cause significant respiratory irritation, allergic reactions, and the exact symptoms you describe. The constant AC use circulates these spores throughout your bedroom.

Do not attempt to handle this yourself. Disturbing a large patch can release a massive, concentrated cloud of spores, potentially worsening your family's exposure and symptoms. For a remediation of this scale, professional containment, HEPA filtration, and removal of affected materials is the only safe, effective solution. The Dubai Municipality has specific guidelines for proper mold remediation to prevent cross-contamination.

The immediate step is to address the source. A blocked or leaking condensation drain line from the AC unit is the probable cause, a very common issue here. A certified HVAC technician should inspect and clear the line to stop the moisture. For the mold itself, a professional inspection with lab analysis can identify the species to better understand the health risk and confirm the remediation was successful. Given the symptoms and the size of the growth, this is a prudent course of action.
