Who is responsible for black mold in AC vent?« Back to Previous Page

Based on the conditions you've described in your JVC apartment, the presence of black, fuzzy growth inside the AC vent is a significant indicator of microbial contamination, most likely Stachybotrys chartarum or another toxigenic mold species. This is a serious indoor air quality issue that requires immediate professional attention.

In the UAE, and particularly in Dubai's high-humidity climate, mold growth in AC systems is predominantly caused by condensation buildup within the ductwork, which is a function of the system's design, installation, and maintenance—not occupant usage patterns. The landlord's claim that it is your fault for "not running the AC constantly" is technically incorrect. Continuous AC operation can actually exacerbate condensation issues if the system is not properly sized or maintained. According to typical tenancy contract stipulations and Dubai's rental laws, the property owner is legally responsible for maintaining the structure and fixed mechanical systems, including the central air conditioning and its ductwork, in a safe and habitable condition. This responsibility includes remediating health hazards like mold proliferation within the ventilation system.

You must formally notify your landlord in writing of the issue and request immediate professional remediation. Do not attempt to clean this yourself, as disturbing the mold can aerosolize highly allergenic and potentially toxic spores throughout your living space.

For a definitive assessment and to establish legal liability, we strongly recommend a certified indoor environmental professional from Saniservice conduct a comprehensive inspection. This includes air and surface sampling to identify the mold species and determine the contamination scope. Our team uses specialized tools like borescopes to inspect deep within the ductwork and provides a detailed report that can be used to formally demonstrate the cause and required action to your landlord.
