Is AC mold a serious health risk needing urgent fix?« Back to Previous Page

Yes, AC mold is a health risk that needs to be addressed promptly, especially given your symptoms and the visible growth. The scratchy throat you're experiencing is a common reaction to mold spores being circulated from the leaking unit.

In Dubai's climate, a leaking AC unit creates a perfect environment for mold. The constant humidity and condensation provide the moisture mold needs to thrive. The black spots on your wall indicate that the problem has moved beyond the internal drip pan and is now affecting your building materials, which is a more serious contamination.

You should arrange for a professional inspection within the next week. Prolonged exposure, even to common molds like Cladosporium or Aspergillus, can exacerbate respiratory issues, worsen allergies, and lead to more persistent sinus congestion, particularly for children, the elderly, or anyone with asthma.

A proper inspection will identify the source of the leak for repair and assess the extent of the mold growth. For a situation with visible growth and health symptoms, surface cleaning is not enough. The wall area behind the unit will likely need targeted remediation to prevent spores from spreading, followed by verification that the space is truly clean. Resolving the leak and the mold together is the only way to ensure the problem doesn't return.
