Is AC mold causing my toddler's illness?« Back to Previous Page

Yes, AC mold can absolutely cause or worsen your toddler's respiratory symptoms like a persistent cough and runny nose. The damp wall behind a leaking unit is a prime breeding ground for mold spores, which then get circulated directly into the room's air.

Given the visible growth and your child's ongoing illness, this warrants immediate attention. Do not wait until the weekend. The combination of Dubai's high humidity and a constant moisture source from the AC leak creates a severe amplification risk. The first step is to stop using that AC unit to prevent further spore dispersal.

You need a professional inspection to assess the full extent. The visible wall growth is likely just the tip of the iceberg; mold often spreads inside the wall cavity and within the AC unit itself. A proper assessment will identify the species—while often called "black mold," many types are black and their health impacts vary. For a child, any significant exposure is a concern.

A reputable inspector will use moisture meters and thermal imaging to find hidden dampness and may recommend air or surface sampling to identify the mold type. Remediation must address the root cause—fixing the AC leak—followed by safe containment and removal of the contaminated materials. Until then, keep the toddler out of that room and consider using an air purifier with a HEPA filter in another living space.
