AC leak causing black mold and stuffy nose: urgent?« Back to Previous Page

This situation requires professional attention within the next few days. The combination of a three-week water leak, visible black speckling, and correlating health symptoms strongly suggests active mould growth, which is a common issue in Dubai's climate due to high humidity and constant AC use.

You should not handle this yourself. Disturbing the mould by wiping or spraying it can aerosolize spores, potentially worsening your respiratory symptoms and spreading the contamination throughout the room. The leak itself must be repaired at its source within the AC unit to prevent immediate recurrence; this is not a DIY fix.

For a case like this, a proper inspection involves moisture mapping to find the full extent of water damage behind the wall and air/surface sampling to identify the mould type. This is crucial, as some species are more problematic than others. The remediation process requires isolating the area, using HEPA filtration, and safely removing contaminated materials.

The persistent stuffy noses are a clear indicator that the indoor air quality is compromised. Addressing the root cause—the AC leak and resulting biological growth—is the only way to resolve it. You'll want a provider that can handle both the mechanical repair of the AC unit and the microbial remediation, followed by verification that the spore count in your bedroom air has returned to acceptable levels.
