Is AC vent dust causing my kids' cough?« Back to Previous Page

The grey dust is likely fine sand and construction debris common in Dubai, but the black specks could be mould growth due to our high humidity and constant AC use. This combination is a very common irritant, especially for children, and is likely contributing to their cough.

You should get it professionally inspected and cleaned as soon as possible, not just for the weekend. Mould spores and fine dust are continuously circulated by the AC, prolonging exposure. In a villa like yours in Jumeirah Park, the entire system—including the hidden ductwork and evaporator coil—needs assessment, as visible vent dust is often just the surface layer.

Look for a provider that does more than just wipe the vents. A proper cleaning should include antimicrobial treatment of the evaporator coil and, crucially, inspection with a borescope to check for contamination deep in the ducts. Any reputable company will show you before-and-after evidence of the cleaning, such as photos or lab results, to verify the job's effectiveness.
