AC leak causing black mold; clean or call professional?« Back to Previous Page

Black speckles from a persistent AC leak in JVC are highly likely to be mold, given Dubai's high humidity and the constant condensation from air conditioning. Bleach is not a recommended solution; it only removes surface discoloration on porous materials like drywall but does not kill the root structure, which will allow it to return. The moisture from the leak has likely penetrated the wall, creating an environment for hidden growth.

For a leak that has been ongoing for months, a professional inspection is strongly advised. The inspector will use a moisture meter to determine the extent of water damage within the wall cavity and may recommend an air or surface sample sent to a microbiology lab to identify the spore types and concentration. This data is critical for determining the correct remediation protocol, as some species require more stringent containment procedures.

Under Dubai Municipality guidelines, significant mold contamination, especially when it involves building materials, should be addressed by certified professionals to prevent cross-contamination and ensure it is removed safely. The first and most critical step is to stop the source by having your AC unit repaired to prevent the problem from immediately recurring after any cleaning is done.
