How to fix AC leak and clean mold from carpet?« Back to Previous Page

The immediate fix is to stop the AC leak, which is likely a blocked condensate drain line—a very common issue in Dubai's climate where ACs run constantly. You'll need an HVAC technician to clear the blockage and ensure the drain pan is functioning. Until that's resolved, no amount of cleaning will prevent the mold from returning, as the damp carpet provides the perfect environment for growth.

For the existing mold on the carpet, surface wiping only removes the visible spores. The mold's root structure (mycelium) penetrates deep into the carpet fibers and backing. A professional-grade antimicrobial treatment is needed to reach and neutralize this embedded growth. For a small area, a thorough cleaning with a solution of white vinegar or a dedicated carpet-safe antimicrobial cleaner can help, but it must be followed by complete drying. Use a wet/dry vacuum to extract as much moisture as possible and a dehumidifier in the room to accelerate drying.

The long-term solution requires addressing both parts: the AC leak and the moisture in the building materials. If the carpet has been wet for more than 48-72 hours, there is a high probability that mold has spread to the underlay and possibly the subfloor beneath. This is a health risk and often requires removal of the affected carpet section and professional remediation of the floor to prevent spores from circulating in your AC system.

Given the persistent leak and visible growth, a professional inspection is strongly advised to assess the full extent of the moisture damage and provide a verifiable cleanup. In many Dubai apartments, this is a strata issue, so you should also notify your building management about the AC leak.
