How to treat AC leak mold and who to fix it?« Back to Previous Page

The black spots are likely mold growth from the AC condensate leak, a common issue in Dubai's humidity. First, address the moisture source. Turn off the AC unit at the circuit breaker to stop the leak and prevent electrical hazards.

For small areas, a solution of white vinegar or a diluted bleach mixture (1 part bleach to 10 parts water) can be used to clean non-porous surfaces. Wear an N95 mask, gloves, and goggles. However, if the mold is on drywall or has spread behind the wall, cleaning the surface is only temporary; the damp material itself often needs professional removal to prevent spores from returning.

The AC repair requires a licensed HVAC technician. They will need to unclog the condensate drain line, check the drain pan, and ensure the unit is properly levelled. In Dubai, technicians should be certified by recognized bodies like DTCM or have DEWA approval for electrical work. Fixing the leak is the only way to stop the mold problem permanently.

Given the persistent dampness and hidden location behind a curtain, a professional mold inspection is advisable to assess the full extent. They can use moisture meters and borescopes to check inside the wall cavity. For villas, leaks can sometimes seep into partition walls, requiring more extensive remediation. A science-driven company with its own microbiology lab can identify the mold type and provide a targeted remediation protocol, which is crucial for families with allergies or respiratory sensitivities.
