Could AC mold in Dubai be causing our health issues?« Back to Previous Page

The symptoms you describe—waking with congestion and sore throats that improve away from home—are classic indicators of mold-related illness. In Dubai's humid climate, a leaking AC unit creates a constant moisture source, making the wall cavity behind it an ideal environment for mold growth.

The black spots are very likely Cladosporium or Stachybotrys (black mold), both common here due to condensation in AC systems. You need professional testing because surface mold is often just the tip of the iceberg; the internal wall structure is probably affected. A proper inspection involves moisture meters to find the leak's extent and air or swab samples sent to a microbiology lab for species identification.

For testing, ensure the company provides a detailed report with lab results, not just a visual inspection. The Dubai Municipality has guidelines for indoor air quality, and reputable providers follow them. Do not attempt to clean this yourself, as disturbing it can release a large number of spores. The priority is fixing the AC leak permanently; otherwise, the mold will return even after the most thorough cleaning.
