Is black mold from AC leak a health risk?« Back to Previous Page

The AC in our bedroom has been leaking for a while, and now we’ve just found a huge patch of black and green mold behind the wardrobe. It’s been getting worse since the humidity spiked last month. My husband has started waking up with a stuffy nose and itchy eyes every morning. Should we be worried and what’s the first step we should take to deal with this safely?

Yes, black mold resulting from an AC leak is a significant health risk and should be addressed immediately. In the UAE's climate, where high humidity and year-round AC use are the norm, such leaks create the perfect environment for rapid mold growth, particularly toxic species like Stachybotrys chartarum (black mold) and Aspergillus.

The symptoms your husband is experiencing—waking up with a stuffy nose and itchy eyes—are classic indicators of mold exposure. These are allergic reactions to the mold spores being circulated by the AC system. Prolonged exposure can escalate to more severe respiratory issues, chronic sinusitis, and persistent headaches, especially in individuals with compromised immune systems or pre-existing conditions like asthma.

The first and most critical step is to cease using that AC unit to prevent further spore dissemination. Do not attempt to disturb or clean the mold yourself, as this will aerosolize the spores and drastically increase the concentration in your breathing air, potentially making the health effects much worse.

This situation requires a professional assessment. In Dubai, proper mold remediation is not just about cleaning; it involves identifying the moisture source, containing the area to prevent cross-contamination, removing the contaminated materials (like the drywall behind the wardrobe), and performing a thorough hygienization of the space using industrial-grade HEPA filtration and antimicrobial agents. Our certified inspectors at Saniservice are equipped to conduct comprehensive air and surface sampling to identify the mold species and the full extent of the infestation, which is often not visible to the naked eye.

For immediate and safe remediation, we strongly recommend you call our experts at 800-MOLDS (800-66537) or email hello@saniservice.com to schedule an inspection.
