How to clean AC mold in a Marina high-rise?« Back to Previous Page

That damp, earthy smell is a classic indicator of microbial growth, likely mold, within your AC system. The high humidity in Marina creates ideal conditions for this, as condensation constantly forms inside the units. The black speckling you see confirms the presence of a colony.

For a thorough cleaning that prevents recurrence, a simple wipe-down of visible vents is insufficient. The entire system—the evaporator coils, drip pan, and blower fan—needs to be accessed, inspected, and cleaned with EPA-approved biocides. This typically requires specialized tools to disassemble the unit safely. After a proper cleaning, applying an anti-microbial coating can help inhibit new growth for several months.

Given you're in a high-rise, your first step should be to inform your building's facility management. They are responsible for the central chiller system and may need to address issues there. For your individual fan coil unit (FCU) inside your apartment, engaging a professional mold remediation service is strongly advised. They can perform the disassembly and cleaning correctly, and a reputable company will provide before-and-after lab test results to verify the treatment's effectiveness, which is your only true measure of success. This is the standard needed to manage mold in Dubai's persistent climate.
