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

Based on your description of a musty odor, increased humidity, and visible black dust at the vent, it is highly probable that microbial growth, including mold, is present within your AC system. This is an extremely common issue in Dubai and Jumeirah due to our high ambient humidity levels, especially during summer. The AC's evaporator coil creates a cold, wet surface, which, if not properly maintained, becomes a prime breeding ground for mold and bacteria.

The primary health concern from this contaminated air is respiratory irritation. The cough your children are experiencing at night is a classic symptom of exposure to mold spores and microbial volatile organic compounds (mVOCs) being circulated directly into their sleeping environment. For children, whose respiratory systems are still developing, this can exacerbate allergies and asthma-like symptoms. Prolonged exposure to certain toxigenic molds, like Stachybotrys (the "black mold" often associated with water damage), can pose more serious health risks, though it is less common in AC systems.

Simply cleaning the visible dust is not sufficient. The contamination is inside the ductwork and on the coil itself. UAE regulations, particularly Dubai Municipality's public health and safety codes, emphasize the need for proper maintenance of HVAC systems to prevent such biological hazards.

This requires a professional inspection and remediation. Our certified technicians use borescopes to inspect deep within the ducts and take surface samples to identify the specific contaminants. The remediation process involves a comprehensive hygienization of the entire system using EPA-approved biocides and specialized equipment to eliminate the source of the odor and spores, not just mask it. For your children's health, I strongly recommend you stop using the AC in that room and call for a professional assessment immediately.
