How to permanently stop AC leak mold on carpet?« Back to Previous Page

The recurrence of black mold from an AC leak in a Mirdif villa is a serious concern that requires a comprehensive technical approach, not just a surface cleaning. The high humidity and constant AC operation in Dubai create a perfect environment for mold to thrive deep within carpet fibers and the underlying subfloor. Permanently stopping it requires addressing both the moisture source and the contaminated materials.

First, the AC leak must be professionally repaired by a certified HVAC technician. This is the non-negotiable first step; without stopping the water intrusion, any remediation will fail. The constant moisture from a leak, combined with our climate, will overwhelm even the best treatments.

For the mold itself, professional inspection and remediation are strongly recommended. DIY cleaning with bleach or vinegar is ineffective on porous materials like carpet and can aerosolize spores, spreading the contamination. UAE regulations and best practices (aligned with standards like IICRC S520) require containment, HEPA filtration, and specialized antimicrobial agents to properly treat and remove the affected materials. The carpet pad is almost certainly a reservoir of hidden mold and must be discarded. Depending on the saturation level, the carpet itself may also need to be removed and replaced. The concrete subfloor must then be professionally cleaned, dried, and treated with an antimicrobial coating to prevent regrowth.

For a permanent solution, I recommend a professional assessment. Our certified inspectors at Saniservice can identify the full extent of the contamination, pinpoint the exact cause of the AC leak, and execute a remediation protocol to ensure the mold does not return.
