AC mold smell: turn it off or keep running?« Back to Previous Page

Based on my professional experience in mold inspection and remediation here in Dubai, I strongly advise you to shut off the AC unit serving the affected bedroom immediately. Do not continue running it.

The black, fuzzy growth you described is a significant concern. When the AC is operational, it actively draws air over the evaporator coil and through the ductwork. If mold is present in the vent or within the unit itself, the system will act as a blower, disseminating mold spores throughout your living space. This not only contaminates other areas but also poses a health risk through inhalation, potentially causing allergic reactions, respiratory irritation, and other issues. The constant AC usage and recent high humidity you mentioned are classic contributors to this problem, as the combination of condensation within the units and Dubai's humid climate creates an ideal environment for mold proliferation.

While the unit is off, refrain from attempting to clean it yourself. Disturbing the mold without proper containment and equipment can exacerbate the spore release. Your next step is a professional assessment. UAE regulations and standards require thorough inspection and remediation by certified professionals to ensure the problem is resolved at its source—which could be a clogged drain pan, contaminated ductwork, or an undersized unit causing excessive condensation.
