AC leak causing black spots and sore throat: urgent?« Back to Previous Page

Based on your description, this is a situation that warrants immediate professional attention. The black speckles are highly likely to be microbial growth, commonly referred to as mold, which is actively feeding on the organic material in your wall and the moisture from the AC condensate leak.

The combination of a persistent water source from the leaking AC unit and Dubai's high ambient humidity creates a perfect breeding ground for mold. The fact that you are already experiencing a scratchy throat is a significant indicator that the spores have become airborne and are affecting your indoor air quality. This can exacerbate allergies and lead to more serious respiratory issues over time.

Attempting a DIY remediation with bleach is strongly discouraged. Bleach is ineffective on porous surfaces like drywall, as it only treats the surface mold and leaves the root structure intact. It also introduces excessive moisture and can release harmful chlorine fumes, especially in an enclosed space. More importantly, the root cause—the AC leak—must be professionally diagnosed and repaired to prevent immediate recurrence.

In the UAE, proper mold remediation follows strict protocols for containment, air filtration, and removal of contaminated materials to prevent cross-contamination to other areas of the villa.

I recommend you cease using that AC unit immediately and arrange for a professional inspection. Our certified team at Saniservice can conduct a thorough assessment to identify the extent of the growth, the species of mold present, and the precise source of the moisture. We will then provide a detailed protocol for safe remediation and permanent solution.
