Is black mold in AC dangerous and landlord's responsibility?« Back to Previous Page

Black mold in an AC unit is a legitimate health concern. The symptoms you're describing—stuffy nose, headaches, and a damp odor—are common reactions to mold exposure, which releases spores and microbial volatile organic compounds (mVOCs) into the air you breathe. While not all black-colored mold is the notorious Stachybotrys, its presence indicates a chronic moisture problem that requires professional attention. In Dubai's high humidity, AC systems are prime locations for mold growth due to constant condensation.

Under Dubai's rental law (Law No. 26 of 2007), landlords are generally responsible for maintaining the structural parts of the property, which includes the central air conditioning system and its ductwork. A mold infestation caused by a faulty AC unit, poor insulation leading to condensation, or a leak in the building's structure falls under their obligation to remediate. However, if the mold is due to a tenant's specific action, like severely obstructing airflow or failing to report a leak, the responsibility could shift.

Your first step is to formally notify your landlord or property management company in writing, with photos of the mold. They should arrange for a professional inspection. A proper assessment involves more than a visual check; it requires air and surface sampling analyzed by a microbiology lab to identify the species and concentration, which determines the remediation protocol. Do not attempt to clean it yourself, as disturbing the mold can cause a significant release of spores throughout your apartment. A certified remediation team will contain the area, use HEPA filtration, and address the underlying moisture source to prevent recurrence.
