Is AC mold dangerous and who should clean it?« Back to Previous Page

The damp smell and black growth you found are strong indicators of microbial contamination, and your symptoms are a common reaction. The specific risk depends on the mold species, but any growth inside an AC unit can disperse spores and microbial fragments into the air you breathe all night, causing the irritation, congestion, and sore throat you described.

For a case like this in a Dubai bedroom, you should notify your building management first. They are responsible for the central cooling system and main ducts. However, their standard cleaning often only addresses the external vents and may not resolve an internal contamination issue. The high humidity and constant condensation here create a perfect environment for this problem.

You should consider a specialized indoor environmental professional. They can conduct an inspection with a borescope to assess the extent of growth inside the ductwork and, if necessary, take samples for lab analysis to identify the species. For proper remediation, look for a provider that uses containment procedures to prevent cross-contamination and can provide verifiable before-and-after testing to confirm the unit and duct are truly clean.
