Is black mold from AC dangerous and who to call?« Back to Previous Page

Based on your description, that black, slimy growth is almost certainly a mold colony, likely including Stachybotrys chartarum (often called "black mold") or other species like Cladosporium or Aspergillus, all of which thrive in the constant moisture of a leaking AC drip pan. The symptoms you and your husband are experiencing—stuffy noses and sore throats that resolve when you leave the environment—are classic indicators of mold exposure and poor indoor air quality being circulated by the AC unit.

Yes, this is considered dangerous, especially over prolonged exposure. Certain molds produce mycotoxins and microbial volatile organic compounds (mVOCs) that can cause these allergic reactions and, in some cases, more severe respiratory issues. In the UAE's climate, AC systems are a primary vector for mold proliferation if not maintained, as the high humidity provides an ideal breeding ground.

You should not attempt to clean this yourself. Disturbing the colony without proper containment can aerosolize spores throughout your entire home. This requires professional mold remediation.

You need to call a certified mold inspection and remediation company. They will conduct a thorough assessment, including air and surface sampling to identify the spore types and concentration levels, in line with UAE standards like the Dubai Municipality's public health guidelines. The process involves isolating the area, using HEPA filtration, applying EPA-approved biocides to disinfect, and finally addressing the root cause—fixing the AC leak and ensuring the drip pan and drainage lines are cleared and functioning.
