How to permanently remove dangerous mold from AC leak?« Back to Previous Page

The AC in our apartment in Jumeirah Village Circle has been leaking a little for a while, but after the recent humidity, I noticed black spots spreading on the wall behind the unit. My husband and I have both had constant headaches and a stuffy nose for the last two weeks that clears up when we go to work. What's the most effective way to get rid of this mold for good, and should we be getting a professional company to test it?

Stop using the AC unit immediately and address the water leak first. Permanent mold removal is impossible while moisture is present. The black spots on the wall indicate active growth, and your symptoms clearing when you leave the apartment strongly suggest a mold-related cause.

For a leak of this duration and visible spread, a professional assessment is strongly recommended. The high humidity in Dubai provides ideal conditions for mold to colonize not just the wall surface but also the cavity behind it and potentially the AC unit's internal evaporator coils. A proper inspection will determine the full extent of the contamination.

Effective remediation involves three steps: fixing the leak at its source to stop moisture intrusion, removing all contaminated porous materials like drywall and insulation, and thoroughly cleaning all affected non-porous surfaces with EPA-approved antimicrobial solutions. Simply wiping the visible spots is insufficient, as hidden growth will continue to release spores and cause symptoms.

Given your health symptoms, testing is advisable to identify the mold species, which informs the safety protocols for removal. In the UAE, companies with their own microbiology labs can provide this analysis. After remediation, a post-clearance test is the only way to verify the environment is safe and the problem has been resolved permanently.
