How to quickly test and clean moldy AC?« Back to Previous Page

That combination of a leaking AC, black speckles, and new respiratory symptoms strongly suggests a mould issue that needs professional attention. The constant humidity and year-round AC use in Dubai creates ideal conditions for mould growth inside units, especially when a leak provides a consistent moisture source.

The fastest path is to engage a company that starts with an inspection, including a tape-lift or air sample sent to an independent microbiology lab for identification. This tells you exactly what species you're dealing with and the associated health risks. Avoid any service that immediately proposes a full clean without diagnostics; proper remediation is dictated by the lab results.

For a legitimate clean, the process must address the source. A technician should first fix the leak causing the condensation. The cleaning itself isn't just spraying a fragrance; it involves dismantling the unit to access the evaporator coils and drip pan, where microbial slime (biofilm) builds up. Effective remediation uses EPA-approved biocides to kill the mould and enzymatic cleaners to break down the organic matter it feeds on.

A credible company will provide before-and-after proof, typically in the form of lab reports showing a quantifiable reduction in spore counts. They should also explain the cause and offer advice on preventing recurrence, like maintaining a specific humidity level. For a situation that's already causing health symptoms, a professional inspection and lab-based approach is the most reliable solution.
