Is our AC leak causing black mold and making us sick?« Back to Previous Page

Based on your detailed description, it is highly probable that you are dealing with a mold colony, potentially including Stachybotrys chartarum (often referred to as "black mold") or more common species like Cladosporium or Aspergillus niger, which also present as black speckling. The continuous AC leak has created a perfect environment for microbial growth: a constant moisture source combined with organic material (the carpet and its backing) and the warm, humid climate of Dubai that persists year-round.

The symptoms you and your wife are experiencing—a persistent nagging cough and headaches—are classic indicators of exposure to mold mycotoxins and microbial volatile organic compounds (mVOCs) released by active colonies. These can cause allergic reactions, respiratory irritation, and other health issues, particularly in individuals with pre-existing conditions like asthma or weakened immune systems.

This is a serious case that requires immediate professional attention. DIY cleaning is not recommended, as improper handling can aerosolize the spores and contaminate the entire apartment. In the UAE, remediation must adhere to strict standards like the Dubai Municipality code of practice, which mandates proper containment, removal, and disposal protocols to protect occupant health and prevent cross-contamination.

I strongly recommend you cease using the AC unit and arrange for a professional inspection and indoor air quality (IAQ) test. Our certified team at Saniservice can conduct a thorough assessment, including moisture mapping and air/o-surface sampling, to identify the species and extent of contamination. We will then provide a detailed protocol for safe, effective remediation and post-clearance testing to ensure your home is returned to a healthy state.
