Should I call an AC cleaner or mold specialist?« Back to Previous Page

Call a specialist for this case. What you describe – a persistent damp smell with visible black growth inside the vent – suggests a contamination issue that goes beyond a standard AC clean. In Dubai's climate, continuous AC operation creates constant condensation, providing the perfect environment for mold to thrive inside the ductwork itself.

A general AC cleaner will likely just clean the visible surfaces, not diagnose the source of moisture or identify the mold type. A specialist will conduct an inspection, often using a boroscope to see deep inside the ducts, and should take a sample for lab analysis to confirm if it's the notorious Stachybotrys (true "black mold") or another common but still problematic species. This diagnosis is critical for determining the correct remediation protocol.

For a villa unit, the process typically involves containment of the area, HEPA vacuuming of the entire duct system, and antimicrobial treatment. The cost is driven by the extent of the contamination and the complexity of your HVAC system; a multi-zone villa will be more involved than a single unit. Always request a detailed assessment and a scope of work that includes post-remediation verification to ensure the issue is resolved.
