How to permanently remove mold caused by AC leak?« Back to Previous Page

The AC leak is the root cause that must be fixed first. Permanent mold removal is impossible while the moisture source remains. In Dubai's high humidity, any dampness will quickly lead to regrowth, which is why the bleach treatment failed—it only addressed surface discoloration, not the moisture or the mold's root structure within the material.

Your immediate step is to have an HVAC technician repair the AC condensate drain line, which is likely clogged. This is a common issue here due to dust and microbial growth within the lines. Until that leak is fully stopped, the problem will persist.

For the mold itself, professional remediation is strongly advised for this scenario. The mold is behind furniture, suggesting it may have spread into the wall or carpet backing. Effective remediation requires isolating the area, removing contaminated porous materials like that section of carpet and possibly a portion of the drywall, and using HEPA vacuuming and antimicrobial treatments. DIY methods often disturb the mold, causing spores to spread to other areas of the home.

After the leak is repaired and the mold is professionally removed, controlling indoor humidity is key to prevention. Ensure your AC unit is correctly sized and functioning to effectively dehumidify the air. Using a dehumidifier in the bedroom can provide additional protection, especially during the more humid winter months. A post-remediation verification test from an independent lab is the only way to confirm the space has been returned to a healthy condition.
