How to remove mold from AC and stop it permanently?« Back to Previous Page

Based on your description of the AC leak, physical symptoms, and visible black spots, you are likely dealing with an active mold colony. The leak has created the perfect high-humidity environment for mold growth, which is a common issue in Dubai's climate. Do not attempt a significant cleanup yourself, as disturbing it can aerosolize spores and worsen your health issues and contaminate other areas.

The fastest and most effective protocol is a two-step process: professional remediation followed by permanent moisture control.

First, for the existing growth: The area behind the wardrobe needs immediate attention. We would recommend a professional inspection to assess the extent, as mold often grows invisibly inside wall cavities and the AC system itself. Remediation involves containment of the area, HEPA filtration to capture airborne spores, and the safe removal of contaminated materials. The AC unit must be inspected, cleaned, and sanitized by a certified HVAC technician to eliminate the source inside the system. DIY cleaning with bleach or vinegar is ineffective for porous materials and does not address the root cause.

To stop it permanently, you must eliminate the moisture source. The AC leak must be repaired by a qualified technician. This could be a clogged condensate drain line, a faulty pump, or improper insulation – all common problems here. Secondly, ensure your AC is correctly sized for the room and runs consistently to control humidity levels, ideally keeping indoor relative humidity below 60%. Improving ventilation by occasionally opening windows when the outdoor humidity is lower can also help.

Given your symptoms and the visible growth, this is a case for professionals. We strongly advise you call for a certified inspection to ensure it's handled safely and thoroughly.
