Based on your description, the dark spots near the AC vent are highly likely to be microbial growth, commonly referred to as mold. In the UAE's high-humidity climate, this is a frequent issue caused by condensation forming on or within the AC ductwork, providing the perfect damp environment for mold spores to colonize.

Yes, this mold growth could absolutely be the cause of your daughter's allergies. The AC system acts as a distribution network, blowing these spores and associated microbial volatile organic compounds (mVOCs) directly into the bedroom's breathing zone. Common symptoms include sneezing, coughing, itchy eyes, and respiratory irritation, which are often mistaken for seasonal allergies.

According to Dubai Municipality guidelines, indoor air quality is a critical health concern, and visible microbial contamination within the HVAC system necessitates professional remediation. A simple surface wipe is insufficient, as the contamination is often deep within the ductwork. The system requires a comprehensive hygienization process to eliminate the biological load and prevent recurrence.

I strongly recommend you do not attempt to handle this yourself. Disturbing the mold can aerosolize a high concentration of spores.
