Black mold near AC vent: Who is responsible for cleaning?« Back to Previous Page

Good afternoon. This is a very common issue we see in Mirdif and across Dubai, especially during the more humid summer months. The black spots forming around your AC vent are a significant indicator of microbial growth, often referred to as mold. The combination of high humidity and reduced cooling efficiency from your AC unit is a major red flag; it suggests the problem is likely inside the ductwork or, as you suspect, originating from the chiller unit itself.

Regarding responsibility, this is a crucial point for UAE residents. Typically, the chiller unit and the main distribution lines are the responsibility of the building management, as they are part of the central cooling system. However, the internal ductwork that runs from the main line into your specific apartment and the vent itself are almost always the responsibility of the tenant or property owner. You should first review your tenancy contract and then formally notify your building management or owner's association about the issue. They are obligated to inspect and address problems with the central chiller.

For a case like this, a professional inspection is non-negotiable. Disturbing the mold yourself can cause spores to spread throughout your home. We use specialized tools like borescopes to inspect inside the ducts and air quality tests to identify the spore types and concentration. This determines the correct remediation protocol.

The fastest way to get a reputable company involved is to contact a certified environmental services provider. We can coordinate with building management to access the chiller room and handle the entire process from inspection to hygienization.
