Mold around AC vent: DIY cleaning or professional help?« Back to Previous Page

Black spots around AC vents are a common issue in Dubai's humid climate, often indicating active mold growth. The condensation from constant AC use creates a perfect damp environment for mold, especially in villas where ductwork can be extensive.

For a small, surface-level patch, a thorough DIY cleaning with a solution like diluted bleach or a dedicated mold cleaner can be effective. However, since the smell returns quickly after wiping, it suggests the mold is not just on the surface but has penetrated the porous drywall or is growing deeper within the ductwork. Vinegar and surface cleaning won't reach this.

In this case, with children experiencing persistent respiratory symptoms, professional assessment is strongly advised. The type of mold matters; some species common in AC systems, like Aspergillus, are known to cause and exacerbate coughing and allergies. A proper inspection will identify the extent of the contamination inside the ducts and the specific species present, which is crucial for understanding the health risk.

For a complete solution, a reputable remediation company will contain the area, safely remove contaminated porous materials like drywall, and perform antimicrobial treatment on the ducts. They should also diagnose and address the underlying moisture source, which is often excessive condensation due to AC temperature settings or insufficient insulation. Finally, post-remediation verification testing is the only way to confirm the environment has been returned to a healthy state.
