Is black mold causing our AC sickness in Dubai?« Back to Previous Page

That black speckling and the damp smell strongly suggest microbial growth, which is a common issue with AC units in Dubai's climate. Your husband's symptoms—especially worsening at night in that room—are consistent with exposure to mold spores or bacteria being circulated by the system.

While you can check for visible signs, a proper inspection here is best left to professionals. DIY tests from online stores are often unreliable in our high-humidity environment and cannot identify the specific species or the full extent of the contamination inside the ductwork. The constant condensation in AC systems creates a perfect breeding ground, and the problem is often deeper than what's visible on a carpet underside.

A certified inspector will use tools like borescopes to look inside ducts and moisture meters to find hidden dampness. The most critical step is air and surface sampling sent to an accredited microbiology lab for analysis. This identifies exactly what you're dealing with—whether it's the more common Cladosporium or the more problematic Stachybotrys (black mold)—and determines the appropriate remediation strategy. Reputable companies in Dubai should provide you with a detailed report including these lab results, which is essential for any effective cleanup. Given the symptoms and visible growth, getting a professional assessment is the recommended course of action.
