Is AC mold causing my husband's cough in Dubai?« Back to Previous Page

Yes, AC mold is a likely cause of your husband's persistent cough and stuffy nose, especially in Dubai's humid climate. The damp smell and black spots are strong indicators of microbial growth inside the unit. Constant AC use creates condensation, which, combined with dust, forms an ideal environment for mold. The system then circulates these spores directly into your bedroom air, often triggering respiratory irritation.

For a proper resolution, you need two distinct services. First, call a certified mold inspector to conduct air and surface sampling. This is crucial because the black spots may only be a fraction of the problem; the main contamination is often hidden deep within the ductwork or evaporator coil. They should provide a lab report identifying the mold species and spore count.

Once you have the diagnostic report, hire a separate remediation company to perform the cleaning. They must dismantle and clean the internal components, not just spray disinfectant. In Dubai, look for providers certified by the Dubai Municipality or those who follow international standards like IICRC. The cleaning process should include containment measures to prevent cross-contamination and a post-remediation verification test to confirm the mold levels have been measurably reduced.
