AC leak causing mold: who to call first?« Back to Previous Page

Call an AC technician first, as they are licensed to address the source of the moisture. The leak must be repaired to stop water intrusion; otherwise, any cleaning will be temporary. In Dubai’s climate, an AC unit leaking cold water onto warm carpet creates a perfect, constant environment for mold growth.

For the visible black spots, a small affected area (under one square meter) can sometimes be managed by carefully cleaning with a detergent solution. However, this only addresses surface growth and the underlying carpet and padding are likely already colonized, requiring professional drying and antimicrobial treatment to prevent recurrence.

If the dampness has persisted for weeks, the mold growth is likely more extensive than what is visible. The high humidity will have allowed spores to spread. For a proper resolution, a professional inspection after the AC repair is recommended to assess the full extent and confirm the species, as some types common in AC systems can cause significant irritation. This ensures the remediation protocol is science-driven and not just cosmetic.
