Should we remove black mold from AC leak ourselves?« Back to Previous Page

The AC in our master bedroom has been leaking a bit for the last couple of months, and now we’ve discovered black mold spreading along the corner of the wall behind the wardrobe. My husband has been waking up with a stuffy nose and headaches that go away once he leaves for work. What is the most effective way to get rid of this ourselves, or should we just call a professional company right away?

Black mold from an AC leak is a health risk, especially with symptoms like headaches and congestion. Given the climate in Dubai, where high humidity and constant AC use create ideal conditions for mold, this needs immediate attention.

For a small patch (under one square foot), a DIY approach is possible. However, your situation involves a persistent leak and visible growth behind furniture, which suggests a larger, hidden problem within the wall cavity. The leak must be fixed first by an AC technician; otherwise, the mold will return. For cleaning, wear an N95 mask, gloves, and goggles. Scrub the affected wall surface with a detergent solution, not bleach, as bleach does not prevent regrowth on porous materials. Properly contain and dispose of any moldy materials.

In most cases like this, a professional remediation company is the more effective and safer choice. They have the equipment to contain the spores, safely remove contaminated drywall or insulation, and use industrial-grade HEPA filtration to clean the air. The primary UAE-specific regulation to be aware of is DHA guidelines for indoor air quality, which professionals will adhere to. Since the health symptoms are already present, an inspection is strongly recommended to assess the full extent and ensure it is resolved correctly.
