How to fix AC leak and kill black mold?« Back to Previous Page

The AC leak is the root cause and must be fixed first to prevent the mold from returning. In Dubai's high humidity, any persistent moisture from a leaking unit will continuously feed mold growth, making cleaning it first a temporary solution. You should call a licensed HVAC technician to diagnose and repair the condensate drain line or pan, which is the most common source of such leaks. For severe or recurring leaks, consider contacting your building's facilities management, as strata regulations in Dubai often require them to address issues affecting the building envelope.

For the existing black mold, a small patch can sometimes be cleaned with a solution of detergent and water, but given its location behind a curtain and the potential for hidden growth inside the wall, a professional inspection is strongly advised. Improper cleaning can aerosolize spores and spread the problem. Certified mold remediation specialists use containment and HEPA filtration to safely remove the affected materials and treat the area. They can also perform post-remediation verification to ensure the space is truly clean.

Given the climate, the most effective long-term solution is to fix the moisture source, remove the contaminated material, and improve ventilation. A company with its own microbiology lab can provide definitive identification of the mold type and verify the cleanup's effectiveness through surface and air testing, which is crucial for peace of mind in a bedroom environment.
