Is mold from AC leak urgent or treatable myself?« Back to Previous Page

This is an urgent situation that requires a professional inspection, not a DIY approach with bleach. The combination of a persistent AC leak, Dubai's high ambient humidity, and the appearance of black spots on both a wall and organic materials like leather indicates an active colony. Bleach only removes surface discoloration on non-porous materials and does not address the root moisture problem or the hyphae (roots) growing within the wall.

The leak is providing a constant moisture source, and the closet’s confined space creates a perfect microclimate for mold proliferation. Given the duration, it is highly likely there is growth within the wall cavity itself, which you cannot see or effectively treat. For health and property integrity, the priority is stopping the leak at its source—this is a job for an AC technician. Once the moisture source is fixed, a mold inspection is critical to determine the extent of contamination.

An inspection involves more than looking; it uses moisture meters and thermal imaging to find hidden dampness and often requires air or surface sampling to identify the species. This is important as some types common in AC systems can cause more significant irritation. In Dubai, resolving the underlying cause of moisture is the mandated first step before any remediation can be successful. Handling contaminated materials like your leather bags also requires specific techniques to avoid cross-contamination throughout your home. Your best course is to call an AC technician immediately to stop the leak, then a certified mold inspector to assess the damage.
