Could my AC leak be causing toxic mold sickness?« Back to Previous Page

Yes, your AC leak is very likely causing mold growth and your symptoms are consistent with mold exposure. The constant moisture from a leak creates an ideal environment for mold, especially in Dubai's climate where high humidity prevents it from drying naturally. The black spots are a clear visual indicator, and the persistent sinus issues and headaches are common health effects from inhaling mold spores circulating in the air.

You should contact a certified indoor environmental professional or a mold inspection company that has its own microbiology lab. This is critical because they can properly identify the mold species through lab analysis, which determines the potential health risk and the correct remediation method. Avoid general handymen or AC repair teams who may clean the visible mold but miss the underlying infestation inside your AC unit or walls, which requires specialized techniques to contain and remove.

The process should start with a thorough inspection, including air and surface sampling sent to a lab. Remediation involves containing the area, removing contaminated materials like damaged drywall, and a deep clean of your AC system with EPA-approved disinfectants. After remediation, a clearance test from the lab is the only way to verify the mold count has returned to a safe level. For your health, addressing this promptly is essential.
