AC leak causing mold and sickness in Dubai?« Back to Previous Page

Leaking AC units in Dubai's humidity are a primary cause of indoor mould. The black spots and your symptoms—stuffy noses and headaches that resolve when you leave—are strong indicators of a mould-related air quality issue. The constant moisture from the leak, combined with our climate, creates an ideal environment for mould growth inside the wall cavity, which then releases spores into your bedroom air.

For a situation involving persistent water damage and health symptoms, a professional inspection is strongly advised. A proper inspection involves more than a visual check; it should include moisture mapping with a thermal camera to find the full extent of water spread and air/surface sampling to identify the mould species and concentration levels. This data is crucial for planning an effective remediation.

In Dubai, look for a provider with a certified mould inspector (like from IICRC or IAQA) who operates their own microbiology lab. This ensures they can analyze samples locally without delay, providing you with a detailed report on the types of mould present and the specific health risks they may pose. This report, not just a verbal opinion, is what you need to understand the severity and required next steps.

Given you're in an older Deira building, the inspection should also assess the AC drain line and insulation, as failures there are common in aging systems. Resolving the leak is the first and most critical step; without fixing the source of moisture, any mould cleaning will be temporary.
