AC leak causing mold behind sofa: who to call first?« Back to Previous Page

Call the AC technician first. In Dubai villas, the most common cause for this pattern is a condensate drain line blockage or a leak in the AC unit's drain pan, which drips directly down the wall cavity. The constant humidity and year-round AC use make this a frequent issue. The mold is a secondary symptom of the water intrusion.

Before the technician arrives, pull the sofa away from the wall to improve air circulation. Wipe the visible mold off the surface with a diluted detergent solution (wear a mask and gloves) to prevent immediate spore dispersal, but understand this is only a temporary surface fix.

The technician should locate and clear the blockage, repair any pan leaks, and ensure the condensate is properly draining. Once the water source is confirmed to be stopped, then assess the mold. For a small, contained area like this, a thorough cleaning and drying by a reputable cleaning service may suffice. However, if the dampness has penetrated the drywall or insulation behind, the wall may need to be opened to properly dry and remediate the hidden mold growth, which would require a specialized mold remediation company.

Any company you hire for mold work should provide before-and-after testing to verify the spore count has been returned to normal levels, which is a standard practice for verifiable results in the UAE.
