Urgent: Mold from AC causing sinus issues and cough?« Back to Previous Page

Yes, your symptoms are very likely connected to the mold growth, and this situation requires immediate professional attention. The constant sinus headaches and dry cough are classic signs of exposure to a significant mold colony, particularly the types (like Aspergillus or Cladosporium) that thrive in the damp, dark conditions created by an AC leak in our climate.

In Dubai, the high humidity and year-round AC use create a perfect environment for mold when a unit malfunctions. A leak inside a wall cavity is a severe issue, as it provides hidden moisture and allows the colony to grow extensively out of sight. The "huge patch" you found is just the visible portion; the hidden growth within the wall is likely much larger.

This is urgent. You should not attempt to clean this yourselves. Disturbing a colony of that size will aerosolize a massive amount of spores and mycotoxins, potentially making your symptoms much worse and contaminating your entire apartment. Remediation requires professional containment, removal of affected porous materials (like drywall), and HEPA filtration to clean the air.

For your health, I strongly recommend you both see a doctor to discuss your symptoms and the mold exposure. In the interim, avoid the affected room as much as possible and keep the door closed.

Professionally, you need a certified mold inspector to conduct a full assessment, including moisture mapping and likely air quality testing, to determine the full extent of the damage. They can provide a protocol for a remediation company to follow. Any reputable company will show you a detailed plan for containment and removal, not just offer to spray and wipe. Given the location in a wall, this is a structural issue that must be addressed correctly to prevent it from recurring.
