Is black mold from AC causing our cough?« Back to Previous Page

Based on your description, it is highly probable that the black spots are microbial growth, potentially including Stachybotrys chartarum (often referred to as "black mold"), and that it is the direct cause of your persistent respiratory symptoms. The constant moisture from the leaking AC unit creates an ideal environment for mold proliferation, especially in Dubai's high-humidity climate where condensation within AC units is a common issue.

The mycotoxins and microbial volatile organic compounds (mVOCs) released by this mold colony are known irritants and can cause chronic inflammatory responses in the respiratory system, manifesting as the exact symptoms you describe: a persistent cough, nasal congestion, sore throat, and fatigue. These symptoms typically resolve only after the source of contamination is removed.

In the UAE, the Dubai Municipality has clear guidelines on indoor air quality and building health, emphasizing the importance of addressing such moisture issues promptly to prevent microbial amplification. A simple surface cleaning is insufficient and can aerosolize the spores, worsening the contamination.

For this scenario, I strongly recommend a professional inspection. Our certified mold inspectors at Saniservice use tools like borescopes to inspect inside your AC ductwork and moisture meters to map the extent of water damage in the wall cavity. This is followed by air and surface sampling to identify the specific species and spore concentration levels, which is crucial for determining the correct remediation protocol.

Do not attempt to handle this yourself. For a proper assessment and a comprehensive remediation plan to safeguard your family's health, please call our experts at 800-MOLDS (800-66537) or email hello@saniservice.com.
