aC leak causing black spots: DIY clean or call inspector?« Back to Previous Page

The black spots and ongoing leak warrant a professional inspection, especially in a villa in Jumeirah. While a surface clean might remove visible spots, the leak has likely created moisture inside the wall cavity and AC ducting, an ideal environment for hidden mold growth in Dubai's humid climate. Bleach is ineffective on porous surfaces and doesn't address the root cause.

A certified inspector uses moisture meters and borescopes to assess moisture levels inside walls and air ducts, which is critical after a persistent leak. They also perform air and surface sampling, with analysis at an accredited microbiology lab, to identify the mold species and concentration. This data is essential to understand the health risk and plan an effective remediation, as some molds common in AC systems can cause more than just irritation.

For your situation, DIY is a temporary fix at best. The Dubai municipality's guidelines for healthy buildings emphasize addressing the source of moisture first. A proper inspection will map the full extent of the damage from the leak and provide a clear protocol for remediation, ensuring the problem is solved completely rather than just cosmetically cleaned.
