Is AC mold causing our health issues in Dubai?« Back to Previous Page

Based on your description, it is highly probable that the black spots are microbial growth, likely mold, and your husband's persistent respiratory symptoms are a direct result of exposure to these spores. In Dubai's high-humidity climate, AC units are a primary breeding ground for mold. A small leak creates constant moisture, and when combined with organic dust in the system and the warm, dark environment of the wall cavity, rapid colonization occurs. The airflow from the AC then aerosolizes these spores, distributing them throughout the room where they are inhaled.

Your first step should be to have a professional indoor environmental inspector conduct a thorough assessment. DIY test kits are unreliable and cannot determine the extent of contamination within the AC unit and wall cavity. A certified professional will use tools like moisture meters, borescopes, and air/surface sampling to identify the species and concentration of mold, which is critical for determining the correct remediation protocol. This is not a simple cleaning job; improper handling can exacerbate the problem by dispersing spores throughout your home.

Regarding health, yes, you should consult a physician. Inform them of the suspected mold exposure, as persistent cough and nasal congestion are classic symptoms of mold sensitivity. They can rule out other causes and provide appropriate treatment.

For the remediation, standard cleaning is insufficient. The process requires containment of the area, use of HEPA filtration devices to capture airborne spores, specialized antimicrobial treatments for the AC system and ductwork, and removal and replacement of any irreversibly contaminated porous materials like drywall. In the UAE, companies like Saniservice are trained in these specific protocols and use EPA-approved, Dubai Municipality-compliant products to ensure the problem is resolved at its source and future growth is inhibited.
