Can I clean black mold from AC leak or call pro?« Back to Previous Page

Stop using the AC and address the leak immediately. The black spots are likely mold, thriving on the constant moisture from the leak in your cool, damp room—a common issue in Dubai's humid climate.

For a small area (under one square meter), you can attempt cleaning with a detergent solution, not bleach. Bleach is ineffective on porous surfaces like drywall and can release harmful fumes. However, the wall behind the wardrobe is a serious concern. The mold has likely spread inside the wall cavity and possibly into the AC unit itself, which you cannot see or properly treat. DIY cleaning will only remove surface staining, not the root colony.

In this scenario, professional assessment is strongly advised. They will identify the exact mold species, locate the full extent of the hidden growth, and remediate it correctly, including fixing the AC leak source. For verifiable results, ensure the company provides before-and-after testing from an accredited microbiology lab.
