AC leak causing black mold and scratchy throat: emergency?« Back to Previous Page

The black speckles are likely Stachybotrys chartarum or another mould species, which is a serious concern given your symptoms and the AC leak. The UAE's high humidity and constant AC use create perfect conditions for this. You should address this immediately, not wait for the weekend.

Persistent moisture from an AC leak behind furniture is a primary cause of toxic mould growth. Your scratchy throat is a common physiological response to mould spores, especially in the confined space of a bedroom. Continuing to sleep in that room exposes you to increasing spore levels.

For a case like this, a professional inspection is strongly advised. DIY cleaning on porous surfaces like drywall is often ineffective and can disturb spores, worsening airborne contamination. A certified inspector can identify the exact mould species through lab analysis and determine the extent of the growth behind the wardrobe, which is likely more widespread than what's visible.

The immediate step is to stop the moisture source. Turn off the AC unit and have an AC technician repair the leak. This is non-negotiable; without fixing the leak, any cleaning or remediation will be pointless as the mould will return. Increase ventilation in the room by opening windows if outdoor humidity is low. Until a professional assesses it, limit time spent in the room, especially while sleeping.

Look for a provider that offers independent inspection and testing, not just remediation, to avoid a conflict of interest. They should provide a detailed report with lab results outlining the species and the recommended scope of work.
