Black AC dust causing sickness: need professional cleaning in Dubai?« Back to Previous Page

The black dust from your AC vent is a major red flag, especially with your ongoing respiratory symptoms. In Dubai's high humidity, this is almost certainly a mold colony growing inside the ductwork or on the cooling coils. Wiping the vent disturbs it, releasing more spores and making the problem worse.

This is a job for a professional remediation company, not a standard AC cleaning service. The process must address the hidden source. Proper protocol involves isolating the AC system with containment barriers, using HEPA vacuuming to remove all settled dust, and then steam cleaning or antimicrobial coating of the internal ducts and coils to address the biofilm. Simply spraying a disinfectant is ineffective.

Cost is variable and depends entirely on the infestation's severity and your AC system's size (e.g., single split unit vs. central ducted system). For a proper remediation that includes post-clearance testing to verify the environment is safe, you should request a detailed, on-site assessment and quote. Always choose a provider that conducts a pre- and post-remediation mold spore count to provide verifiable, lab-documented proof that the problem is resolved.
