How to properly inspect for mold from a leaking AC?« Back to Previous Page

A persistent AC leak like you've described is a serious concern, particularly in Dubai's high-humidity climate, as it creates a perfect environment for mold colonization within concealed building cavities. A proper inspection must move beyond a simple visual assessment to identify the full extent of the contamination.

The correct procedure begins with a comprehensive visual inspection using specialized tools. A professional will use a borescope to visually inspect inside the wall cavity behind the unit and the drain pan itself, which often harbors significant microbial growth. Moisture mapping with non-invasive meters (capacitance and thermo-hygrometers) is critical to quantify the moisture content in the surrounding drywall and structure, identifying areas that appear dry but are damp enough to support growth. Surface and air sampling are then employed for laboratory analysis. Air sampling compares spore counts and types inside the closet against an outdoor control sample to determine if an amplification site is active. Tape lift or swab samples from the black spots will provide definitive genus/species identification, which is crucial for designing an effective remediation protocol.

Given that the leak has recurred and you suspect hidden growth, a DIY approach is insufficient and potentially hazardous. Disturbing mold without containment can aerosolize spores throughout your apartment. In the UAE, reputable companies like ours follow strict guidelines akin to IICRC standards. We provide a detailed report with lab results and a scope of work for your building management, which is often necessary for warranty or insurance claims.

For a definitive diagnosis and to prevent ongoing health risks and property damage, I strongly recommend a professional inspection. You can contact our certified team at Saniservice for a thorough assessment by calling 800-MOLDS (800-66537) or emailing hello@saniservice.com.
