Is AC mold causing my family's persistent cough?« Back to Previous Page

Yes, the mould in your AC system is very likely contributing to your family's persistent cough. The black patch you see and the damp smell are strong indicators of microbial growth inside the ductwork, a common issue in Dubai due to high humidity and year-round AC use that creates constant condensation. When the unit operates, it aerosolizes mould spores and fragments, circulating them directly into your breathing air, which can cause significant respiratory irritation, congestion, and worsened allergy symptoms, especially in children.

For a villa in Jumeirah, you need a professional inspection and remediation service that specializes in duct cleaning and disinfection, not just a standard AC maintenance company. The entire system, including the hidden ductwork, evaporator coil, and drip pan, must be addressed. Look for a provider that uses industry standards like NADCA for cleaning and offers before-and-after testing to verify the results. They should be able to show you documented evidence from their own or a third-party microbiology lab confirming the species present and the reduction in spore count post-cleaning. This verifiable data is what separates a proper remediation from a superficial cleaning that just spreads the problem.

Until the service is completed, you can help reduce exposure by regularly replacing your AC's air filter with a high-efficiency one and using a portable HEPA air purifier in the main living areas and bedrooms.
