AC Leak Causing Mold: DIY Fix or Landlord Issue?« Back to Previous Page

The leak is the primary issue that must be fixed first; simply cleaning the mold will not stop it from returning. In Dubai's high humidity, AC condensate drain lines are prone to clogging from dust and microbial growth, which is the most common cause of indoor leaks.

For the immediate mold on the wall, you can clean small patches (under one square meter) yourself. Wear an N95 mask and gloves. Use a diluted vinegar solution or a dedicated mold cleaner, scrub the area, and ensure it is completely dry. Do not use bleach, as it only removes the surface color and does not kill the mold roots embedded in porous materials like drywall.

However, this is a landlord issue for the AC repair. Tenancy laws in Dubai place the responsibility for maintaining major appliances, including the central AC system, on the property owner. You must notify them in writing about the recurring leak and resulting mold growth. They are obligated to address the root cause, which likely requires a qualified AC technician to clear the drain line, check the drain pan, and ensure the unit is draining correctly.

Given the mold has returned, a professional inspection is wise to check for hidden moisture inside the wall or under the carpet, which can lead to more extensive problems. Recurring moisture in our climate almost always indicates an unresolved systemic issue with the appliance or building envelope.
