Can AC mold cause runny nose anf itchy eyes?« Back to Previous Page

Yes, AC mould is a common cause of runny nose and itchy eyes, especially in Dubai's climate. The constant humidity and dust create an ideal environment for mould and microbial growth inside AC systems, which then circulates spores and particulates throughout your home.

The damp, mildewy smell from your bedroom vent strongly indicates microbial presence, likely on the evaporator coils or in the ductwork. The dust blowing from the living unit suggests a significant accumulation of debris that standard filter changes cannot address. In an older Deira building, aged insulation within the ducts can also degrade and become a food source for mould.

For a proper cleaning, avoid companies that only offer a basic spray-and-wipe service. A comprehensive cleaning should include accessing and vacuuming the main duct trunks, mechanically brushing the evaporator coils, and sanitizing the drain pan. The most reliable providers will use truck-mounted vacuum units for powerful extraction and may offer before-and-after documentation, such as video inspections or surface swab results from an independent lab, to verify the reduction of contaminants.

Given the persistent symptoms in children, a professional inspection is advisable to assess the full extent of the issue. This will determine if cleaning is sufficient or if any components, like degraded duct liner, need replacement to prevent recurrence.
