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

The issue you're describing is a classic and serious problem in Dubai's climate. The black speckles are highly likely to be mold growth, potentially Stachybotrys chartarum (black mold) or more commonly Cladosporium, fueled by the constant moisture from your AC leak. This is not a simple cleaning task; it's an environmental contamination issue.

The AC leak is the primary cause that must be addressed first. The most common reasons in UAE systems are a clogged condensate drain line due to dust and microbial growth, a damaged or disconnected drain pan, or insufficient insulation on the cold refrigerant lines causing excessive condensation. A licensed HVAC technician must inspect, unblock, flush the drain line with a biocide, and repair the fault. Simply wiping the drain pan is a temporary fix.

For the mold, do not attempt to clean it with bleach or store-bought products. These are ineffective on porous materials like drywall and can push spores deeper. The damp carpet and affected wall section are likely compromised. UAE regulations, particularly from Dubai Municipality, emphasize proper containment and removal to prevent cross-contamination.

The only permanent solution is source removal. This involves isolating the area, using HEPA filtration to capture airborne spores, safely removing and disposing of the contaminated carpet and drywall, and then thoroughly treating the subfloor and wall cavity with professional-grade antimicrobial solutions.

Given the persistent leak and visible growth, a professional inspection is non-negotiable. We use moisture meters and thermal imaging cameras to assess the full extent of the water damage hidden within the walls.
