Can mold in AC cause family coughing and allergies?« Back to Previous Page

Yes, mold in your AC unit is a very common cause of the symptoms you're describing, especially in Dubai's climate. The persistent humidity creates ideal conditions for mold growth inside the ductwork and on the cooling coils, where condensation occurs. When the AC turns on, it can blow these spores directly into your living space, triggering allergic reactions, persistent coughing, and that distinct damp smell.

Given your family's ongoing health issues, a professional inspection is strongly recommended. Look for a company that provides more than a visual check; they should use a borescope to inspect deep inside the ducts and, most importantly, take air and surface samples for analysis by an accredited microbiology lab. This lab analysis is critical—it identifies the specific type of mold present and its concentration, which determines the actual health risk and the necessary scope of any remediation work.

Avoid companies that offer immediate cleaning without testing first. A reputable provider will show verifiable before-and-after data and hold certifications like those from the Indoor Air Quality Association (IAQA). Since you're in a villa, the entire system, including the air handling unit and water tank, should be assessed. The Dubai Municipality has guidelines on indoor air quality, and a proper inspection will align with these standards to give you a clear, actionable report.
