How to fix moldy AC and health issues in Dubai?« Back to Previous Page

Based on your description of a moldy smell, visible black growth inside the AC unit, and associated health symptoms like a scratchy throat and headaches, you are dealing with a significant microbial contamination issue. This is extremely common in Dubai due to the high humidity and year-round AC operation, which creates constant condensation—the perfect environment for mold growth inside the ductwork and evaporator coils.

The most effective and safe method is not a simple cleaning but a comprehensive professional hygienization process. DIY cleaning with store-bought sprays is insufficient and can aerosolize spores, worsening your health symptoms and spreading contamination. The procedure must follow UAE standards, such as those outlined by Dubai Municipality and the Civil Defence, which often require certified specialists for HVAC work.

A proper remediation involves several technical steps: First, a detailed inspection with borescopes and possibly air quality testing to assess the extent. The system is then isolated. Specialized anti-microbial foams and disinfectants, approved for use in air handling systems, are applied to the evaporator coils, drain pan, and interior duct surfaces. These agents are designed to penetrate biofilm, kill the microorganisms at the root, and inhibit future growth. Finally, the entire system is flushed and a protective coating may be applied. The filter should be replaced with a higher-grade MERV-rated filter.

For your health to fully recover, the source must be completely eliminated. We strongly recommend you contact a certified professional immediately.
