AC mold issue: urgent professional help needed?« Back to Previous Page

That visible patch from a leaking AC unit is a definite concern, especially with rising humidity accelerating its growth. The leak means there is likely a significant amount of hidden moisture and mold inside your wall cavity and possibly the AC unit itself, which is the primary issue.

For a leak that has persisted for weeks, this is a case for a professional assessment. DIY bleach is not recommended; it only bleaches the surface mold you can see and does not address the root moisture problem or the colony growing within the wall. The high humidity will cause it to return quickly. Professionals use containment procedures and specialized antimicrobials to treat the entire affected area and identify the source of the moisture—in this case, the leaking AC, which will also need to be repaired.

In Dubai's climate, where AC systems run year-round, this type of condensation issue is common and requires a comprehensive solution. A proper inspection will determine the extent of the spread and the correct protocol for removal to prevent it from affecting your indoor air quality. Given the timeline, scheduling an assessment this week is advisable to prevent further spread.
