AC leak causing mold and child's stuffy nose?« Back to Previous Page

The black spots are likely mould, and the persistent AC leak is the moisture source it needs to grow. Your child's morning congestion is a common reaction to sleeping in a room with elevated mould spore levels, as it irritates the respiratory tract.

Do not attempt to clean it yourself with bleach or other household cleaners. Disturbing the mould without proper containment can aerosolize a high concentration of spores, potentially worsening the air quality and your child's symptoms. The priority is stopping the moisture source.

A professional HVAC technician should inspect and repair the AC unit leak first. In Dubai's climate, continuous condensation from a faulty unit creates a perpetual damp environment. Until that leak is fixed, any cleaning is temporary.

After the repair, the mould remediation can be addressed. For a small, contained area, a specialist can often clean it using EPA-approved biocides and HEPA vacuuming. However, given its location on a wall (a porous surface) and its connection to a child's health, a professional inspection is strongly advised to assess the extent. They can perform surface and air quality testing to identify the mould type and confirm spore counts have returned to a normal baseline after remediation, which is the only way to verify the problem is truly resolved.
