AC leak causing mold inside walls, how to inspect?« Back to Previous Page

A constant AC leak in a Dubai villa is a serious moisture issue that almost certainly indicates hidden mold growth. The combination of 24/7 cooling and our high ambient humidity creates perfect conditions for mold to thrive inside wall cavities and AC ducts, long before it becomes visible on the surface.

For a situation like this, a visual check is insufficient. You need a professional inspection that includes three key components. First, a borescope inspection to see inside your wall cavities and ductwork without destructive drilling. Second, moisture mapping with a professional-grade meter to identify the full extent of water intrusion behind the walls. Third, and most critically, air and surface sampling to be analyzed by an accredited microbiology lab. This identifies the mold species and concentration, which is essential for assessing the health risk and planning an effective remediation strategy.

In Dubai, look for a provider certified by organisations like the IICRC and one that operates its own lab. This ensures the inspector is also the analyst, providing a direct link from the sample to the scientific results. The final report should clearly state the species found, the spore count levels indoors versus outdoors, and a detailed protocol for remediation, not just a simple cleaning recommendation.

Address the AC leak at its source immediately—this is the root cause. A qualified HVAC technician should repair the condensation drain line or faulty insulation. Without fixing the leak, any mold removal will be temporary, as the moisture will cause it to return.
