How can I fix AC mold and stop it permanently?« Back to Previous Page

The black speckles are likely mold growth due to moisture from the AC leak, amplified by Dubai's high humidity. For a small area, clean it with a solution of white vinegar or a dedicated mold remover, scrubbing gently. Always wear an N95 mask and gloves to avoid inhaling spores.

Stopping it permanently requires fixing the source. The AC leak must be repaired; this is non-negotiable. The wall cavity behind may also be wet and contaminated, which DIY cleaning can't address. After the repair, a dehumidifier in that room can help maintain humidity below 50%, making it harder for mold to regrow.

For a recurring issue like this, especially with a known water source, a professional inspection is strongly advised. They use moisture meters to find hidden dampness inside walls and can confirm if the AC coil itself is contaminated, which requires specialized cleaning. In the UAE, proper remediation follows standards like the IICRC S520, which focuses on source removal, not just surface cleaning. A company with its own microbiology lab can also test to identify the mold type, which informs the correct remediation protocol.
