How to dry and treat AC leak to prevent mold?« Back to Previous Page

The AC leak you've described is a classic scenario for mold growth in Dubai's climate. The constant high humidity, especially during summer, combined with condensation from the AC unit, creates a perfect microenvironment for mold spores to colonize organic materials like carpet backing and padding.

Your immediate priority is to dry the area completely. First, address the source: turn off the AC unit to stop further water intrusion. Soak up all standing water with absorbent towels. For the saturated carpet and pad, it is often necessary to lift the carpet from the tack strips to expose the underlying pad and the concrete slab. These layers hold moisture long after the surface feels dry. Use high-velocity air movers (fans) and a dehumidifier, not just a regular fan, for a minimum of 24-48 hours to achieve proper drying. Merely drying the surface is insufficient and will lead to hidden mold growth.

Once the structure is thoroughly dry, the area must be treated. The damp, earthy smell you detect is likely Microbial Volatile Organic Compounds (MVOCs), a strong indicator that microbial activity has already begun. Scrubbing with a detergent solution may remove surface staining but will not address the root issue. A certified antimicrobial treatment is required to neutralize any incipient mold growth and prevent its recurrence.

Given the propensity for hidden damage behind walls and under floors from such leaks, a professional inspection is highly recommended. We use moisture meters and thermal imaging cameras to assess the full extent of water migration, which is almost always greater than what is visible. For a comprehensive assessment and CDC-grade remediation protocols, please contact our specialists at Saniservice.
