How to permanently fix AC leak and black mold?« Back to Previous Page

The black speckles you're seeing are almost certainly mold growth, a common issue in Dubai due to our high humidity levels and the constant use of AC systems. The recurring growth indicates a persistent moisture problem that cannot be solved by surface cleaning alone.

The most effective permanent solution requires a two-pronged approach: addressing the moisture source and professionally remediating the mold. First, the AC unit leak must be fixed. This is often caused by a blocked condensate drain line, a common issue in our dusty environment, or a malfunction in the condensate pump. A licensed HVAC technician should inspect, unclog, or repair the unit to stop the water intrusion at its source. The wet carpet and underlying padding must be thoroughly dried using industrial-grade air movers and dehumidifiers to prevent structural moisture and further microbial growth.

Regarding the mold, wiping it away only removes the visible spores. The fungal roots (hyphae) penetrate porous materials like wood and drywall, which is why it returns. For a permanent fix, the affected skirting board must be professionally assessed. It may require targeted sanding, application of EPA-approved antimicrobial agents, or complete replacement if the infestation is deep. In the UAE, remediation must adhere to strict guidelines to ensure spores are not spread to other parts of the property.

Given the health risks associated with black mold (Stachybotrys chartarum) and the technical nature of both AC repair and mold remediation, I strongly recommend a professional inspection. Our certified team at Saniservice can conduct a comprehensive assessment to identify the exact mold species and moisture points, then execute a complete remediation and hygienization protocol.
