Toxic smell from bedroom vent: who to call?« Back to Previous Page

Building management is responsible for investigating odors from the central AC system, not DEWA. Your first step is to file a formal written complaint with your building's facilities or property manager, detailing the specific location, time of occurrence, and symptoms. They are obligated under Dubai Municipality regulations to address indoor air quality issues originating from the building's central plant.

A persistent chemical smell from a vent, especially one causing headaches and sore throats, is a serious health concern that warrants immediate action. In Dubai's climate, where AC systems run continuously, volatile organic compounds (VOCs) from sources like cleaning solvents, paint, adhesives, or new building materials can be pulled into the ventilation system and distributed. These chemicals can off-gas more noticeably in the evening when temperatures drop slightly and system pressures change.

For your safety, consider minimizing use of that specific AC unit until it is inspected. If the building management is unresponsive or unable to identify the source, the next step is to contact Dubai Municipality's Public Health & Safety Department. They can conduct an inspection and enforce compliance. Given the symptoms, a professional indoor environmental assessment, including air quality testing for VOCs, is strongly recommended to identify the specific contaminant before it can be properly remediated.
