How to find mold source behind AC and walls?« Back to Previous Page

My kids have been coughing and I suspect it's the mold I've spotted in the corners of their bedroom. We've lived here for 2 years and just noticed these black spots behind the wardrobe after I rearranged the room last week. I'm worried the AC unit might be spreading spores throughout the house. What's the best way to get a thorough inspection done to find the actual source and not just treat the visible spots?

A thorough mold inspection starts with identifying the root cause of moisture, which in Dubai is often condensation from AC units or a hidden leak. The black spots behind the wardrobe are a major red flag, suggesting a potential moisture issue in that wall cavity. Since you suspect the AC, the inspection must cover the unit, its condensate drain line, and the surrounding wall.

For a case like this with health symptoms, a professional inspection is strongly recommended. They use tools like borescopes to see inside walls and moisture meters to find hidden dampness that isn't visible. The AC system itself needs a detailed check of the evaporator coils, drip pan, and ductwork for microbial growth, as it can circulate spores.

The goal is to get a complete picture of the contamination, not just sample the visible mold. A proper inspection provides a remediation plan that addresses the source of the moisture first, then the mold itself. Look for providers who can deliver a detailed report with documented findings and a clear scope of work, as this is what separates a diagnostic service from a simple cleaning. Companies with their own microbiology labs can identify the specific species, which is critical for understanding potential health risks and verifying the cleanup was effective.
