AC leak causing black mold: DIY fix or call professional?« Back to Previous Page

Based on your description of a recurring AC leak in Jumeirah and the reappearance of black spots after a DIY attempt, this is a clear case that requires immediate professional intervention, not a stronger cleaning product.

The black spots are almost certainly active mold growth, fueled by the constant moisture from the AC leak. The Dubai climate, with its high humidity and year-round reliance on AC systems, creates a perfect environment for rapid mold proliferation. The condensation from AC units is a primary cause of hidden mold issues here. Your attempt with vinegar is a common mistake; vinegar is not an EPA-approved fungicide and often only bleaches the surface hyphae, causing the colony to regroup and return stronger, as you've experienced.

This is not a simple surface contamination. The leak indicates a problem within the AC system or its drainage, and the mold has likely infiltrated the wall cavity behind the wardrobe. DIY methods cannot address the root cause—the moisture source—nor safely handle the potentially hazardous spores that will be disturbed during cleanup.

According to UAE health and safety guidelines, significant mold infestations, especially those caused by building system failures, should be handled by certified professionals to ensure complete remediation and prevent health risks. We strongly recommend you cease DIY efforts and call for a professional inspection and assessment.

Our certified team at Saniservice uses thermal imaging to trace the exact moisture path, assesses the AC unit, and performs controlled remediation following IICRC standards. We will identify the species of mold, contain the area, remove contaminated materials safely, and apply industrial-grade antimicrobial solutions to ensure it does not return.
