What health problems does moldy AC air cause?« Back to Previous Page

The black spots and symptoms you describe are common in Dubai, where AC units are constantly battling humidity and condensation, creating ideal conditions for mold. The most frequent health issues from breathing moldy AC air are respiratory irritation and allergic reactions. This typically presents as persistent dry coughs, sinus congestion, headaches, sore throats, and worsened asthma or allergy symptoms, which aligns perfectly with what you and your husband are experiencing.

Given the persistent nature of your symptoms and the visible mold growth, a general practitioner is a good first step to address your immediate health concerns. Be sure to tell them about the mold in your bedroom. For the root cause, however, a general doctor cannot help. The leaking AC unit itself requires professional inspection and remediation by a certified indoor environmental professional. They can identify the source of the moisture, assess the extent of the mold contamination within the unit and ductwork, and perform the necessary cleaning to stop the problem.

In many cases, the mold is confined to the unit and its immediate surroundings, and a thorough cleaning resolves the issue. Do not attempt to clean it yourself with store-bought sprays, as this can aerosolize the spores and worsen your exposure. The goal is to stop the moisture leak and have the system professionally cleaned to measurably reduce the spore count in your air.
