How to professionally remove black mold from AC and prevent recurrence?« Back to Previous Page

The AC in our master bedroom has been leaking on and off for a couple of months, and now we’re all waking up with sore throats and stuffy noses. I finally pulled the wardrobe away from the wall behind it in our Jumeirah Park villa and found a huge patch of black mold spreading there. I’m really worried about my family breathing this in every night. What’s the most effective way to get this professionally cleaned and make sure it doesn’t come back?

The most effective method begins with a professional inspection to determine the mold's extent, as it's likely inside the AC unit and ductwork, not just the visible wall. In Dubai's high humidity, simply wiping the surface will fail.

For a confirmed case like this, remediation involves isolating the area, removing contaminated porous materials like drywall or insulation, and using HEPA-filtered equipment to clean the air and surfaces. The AC system itself must be shut down and professionally cleaned to prevent spreading spores. A microbiology lab test before and after is the only way to verify the species and confirm successful removal.

To prevent recurrence, the root cause must be fixed. The AC's persistent leak needs repair by a certified HVAC technician. Afterwards, consider applying a mold-inhibiting coating to the treated area. In villas, maintaining indoor humidity below 60% with a dehumidifier can significantly reduce the risk of regrowth in our climate.
