Is AC mold causing our illness, landlord or us to clean?« Back to Previous Page

Yes, the mold in your AC is very likely causing your symptoms. The black and green growth indicates active colonies that release spores and microbial volatile organic compounds (mVOCs) into the air you breathe all night. Stuffy noses and morning headaches are common reactions to this prolonged exposure.

In Dubai's humid climate, AC units are prime locations for mold due to constant condensation. The standing water in the drain pan and on cooling coils, combined with dust for food, creates an ideal environment for growth, especially if the unit's drain line is partially clogged.

For a Jumeirah apartment, the responsibility for professional cleaning typically falls on the landlord as part of maintaining the property's core systems. You should formally notify them in writing about the visible microbial growth and your health symptoms, requesting a proper remediation. The Dubai Rental Law (Law No. 26 of 2007) generally holds landlords responsible for maintenance of essential facilities, which includes the central air conditioning system.

Do not attempt to clean it yourself with store-bought sprays, as this can aerosolize harmful spores throughout the room. A professional assessment and remediation are needed to properly address the contamination inside the unit and the ductwork, not just the visible vent. A company with microbiological verification can test to confirm the species and verify the cleanup was effective.
