Could black mold from my AC be making us sick?« Back to Previous Page

Yes, the black mould from your AC leak is very likely the cause of the persistent respiratory symptoms. The constant moisture from the leak creates an ideal environment for mould growth, and the types commonly found in such situations are known to cause exactly the symptoms you describe—chronic stuffy nose, coughing, and throat irritation, especially during prolonged exposure while sleeping.

In Dubai's climate, where we rely on AC year-round, these enclosed systems can recirculate spores throughout the room. A fuzzy black patch indicates an active colony that needs immediate attention. Do not attempt to clean it yourself with bleach, as this can aerosolize the spores and worsen the problem.

The fastest, most effective course is a two-step professional process. First, contact a certified mould inspection company to conduct an air and surface sample test. This is crucial to identify the species and concentration, which dictates the remediation protocol. In parallel, you need a reputable remediation specialist to address the source: the AC unit must be repaired to stop the leak, and the affected wall will likely need to be opened, cleaned, and treated. Reputable firms in Dubai should provide before-and-after lab reports to verify the spore count has been returned to safe levels. For health verification, a follow-up test after remediation is recommended.
