Could mold in our AC be causing a cough?« Back to Previous Page

It's highly possible the mold in your AC is contributing to your husband's persistent cough. The damp smell and visible black spots indicate active microbial growth, and the continuous circulation of contaminated air is a common irritant to the respiratory tract. In Dubai's humid climate, AC units are a prime breeding ground for mold due to constant condensation, and this type of exposure often manifests as allergy-like symptoms, including a dry, stubborn cough that doesn't resolve.

Your first step should be a professional indoor air quality inspection. Do not attempt to clean the visible mold yourself, as disturbing it can release a high concentration of spores into your air and worsen the situation. A certified inspector will use specialized equipment, like borescopes, to assess the entire AC ductwork and evaporator coil—the most common source of the problem that you cannot see. They should also take air and surface samples for analysis at an accredited microbiology lab. This lab culture is critical; it identifies the specific type of mold present and confirms whether it's the source of the contamination, which guides the proper remediation method.

In the UAE, look for providers who follow standards like the IICRC S520 for mold remediation. The report from the lab will give you a definitive answer on the health risk and the necessary steps to resolve it, ensuring the cleaning process itself is scientifically validated and not just a superficial treatment.
