How to clean AC mold in JVC apartment and stop smell?« Back to Previous Page

That damp, earthy smell is a classic sign of microbial growth, likely mould, within your AC system. The high humidity and constant condensation in Dubai's climate create an ideal environment for this, especially in areas like JVC where AC runs nearly year-round.

For a DIY approach, you can address the indoor unit. Turn off the AC's power at the circuit breaker. Remove the front grill and wash it with a mild detergent. Carefully clean the visible evaporator coils using a soft brush and a coil cleaner spray designed for AC units—avoid harsh chemicals. Replace the air filter with a new one. This can help reduce the immediate issue, but it rarely solves a recurring problem completely, as the growth is often deep within the ductwork or drain pan.

The fact that the black spots reappeared on your wall strongly indicates an active, persistent source of contamination that superficial cleaning won't fix. The main ductwork running through the building's structure is the most probable culprit and is almost always the responsibility of the building management.

You should formally request that building management inspect and clean the main supply ducts serving your apartment. Reference Dubai Municipality's guidelines on indoor air quality and building maintenance, which hold landlords and property management responsible for the condition of central systems. A professional inspection with camera scoping is the only way to identify the true extent of the contamination in the ducts. For a persistent smell and regrowth, a lab test to identify the mould species can clarify the health risks and necessary remediation steps.
