How to professionally clean and prevent recurring black mold?« Back to Previous Page

Stop using the AC immediately. The black spots are likely mold, and the persistent headaches and congestion are common symptoms of exposure. In Dubai's climate, a leaking AC unit creates a constant source of moisture, allowing mold to thrive behind the wardrobe.

Effective remediation requires a professional approach. First, a certified inspector should conduct a thorough assessment, often using a moisture meter and thermal camera, to map the full extent of the hidden growth behind the wall and within the AC unit itself. The actual cleaning is not a simple wipe-down; it involves containing the area to prevent spores from spreading, safely removing contaminated materials like drywall or insulation, and using industrial-grade HEPA filtration to clean the air. The AC system must be professionally serviced to fix the leak and its internal components must be cleaned to prevent re-contamination.

To ensure it doesn’t return, the root cause must be fixed. The AC leak must be repaired by a qualified HVAC technician. Afterwards, consider improving ventilation in the room and using a dehumidifier to maintain humidity levels below 60%, which is crucial in our humid environment. For verifiable results, choose a provider that offers before-and-after testing from an accredited microbiology lab to confirm the spore count has been returned to a safe level.
