AC leak causing black mold and health issues, what first?« Back to Previous Page

Yes, it is very possible the mold from your AC leak is causing your symptoms. Persistent stuffy nose and dry cough are classic reactions to mold exposure, often mistaken for a lingering cold, especially in Dubai's climate where we're in enclosed, AC-cooled spaces year-round.

The first step is to stop the moisture source. Have a certified HVAC technician repair the AC leak immediately—this is non-negotiable. Until it's fixed, the mold will continue to grow regardless of any cleaning.

For the existing mold, do not attempt to clean it yourself. Disturbing it can release a high concentration of spores into your air, potentially worsening your symptoms. The black speckles suggest visible growth, which often means there is more hidden within the AC unit or the wall.

You need a professional mold inspection. In Dubai, this involves a trained inspector who will assess the extent of the contamination, often using moisture meters and thermal imaging to see behind walls. The most critical part is air and surface sampling, which is sent to an independent microbiology lab (like the one we operate) to identify the exact species. This is essential because it confirms the presence of mold, identifies the type, and dictates the correct remediation protocol.

A proper remediation company will then contain the area, remove the contaminated materials (like sections of drywall or insulation), and use HEPA filtration to clean the air, providing you with before-and-after lab reports to verify the spore count has been returned to a safe level. Always request to see these certified lab results; it's how you distinguish a science-driven service from a superficial cleaning.
