How to stop AC water leak and black mold?« Back to Previous Page

The issue you're describing is a classic symptom of a condensate drain line problem combined with the high ambient humidity of the Dubai climate. The black spots are almost certainly mold growth, fueled by the constant moisture from the leak and the ideal breeding conditions created by our year-round air conditioning use.

The first and most critical step is to address the root cause: the water leak. This is typically due to a blocked condensate drain pan or drain line. The pan can be cleared, but this often requires a certified HVAC technician. Simply wiping the mold away is ineffective, as the microscopic spores remain and will regrow as long as the moisture is present.

For a permanent solution, a professional inspection is strongly recommended. The mold growth inside the AC unit and the ceiling cavity could be more extensive than what is visible. In the UAE, remediation must adhere to strict standards to prevent cross-contamination and ensure complete spore removal. Our certified team at Saniservice uses specialized equipment like moisture meters and borescopes to assess the full extent of the damage behind the walls.

The remediation process involves containing the area, HEPA vacuuming the visible growth, and applying professional-grade antimicrobial agents to hygienize the surface and prevent regrowth. Crucially, the AC system itself must be inspected and cleaned to eliminate the source of contamination.

To stop the damage and ensure your indoor air quality is safe, please contact our specialists for a comprehensive assessment. Call us at 800-MOLDS (800-66537) or email hello@saniservice.com.
