AC leak causing mold and allergies: first step?« Back to Previous Page

The AC unit in my bedroom in our Jumeirah apartment has been leaking a little, and now we’ve found black spots spreading on the wall behind the wardrobe. My husband and I have both had a constant stuffy nose and itchy eyes for the last month, and it’s not getting better. Is this likely a mold issue causing our allergies, and what’s the first step we should take to get it properly inspected and cleaned?

The symptoms and visible black spots strongly indicate a mold issue caused by the AC leak. In Dubai's humid climate, constant condensation from a leaking unit creates the perfect environment for mold growth within days. Your persistent allergy-like symptoms are a common reaction to mold spores circulating in the air from the affected area.

The first step is to stop the moisture source. Have a certified HVAC technician repair the AC leak immediately; this is non-negotiable. Do not attempt to clean the mold yourself, as improper scrubbing can aerosolize a high concentration of spores, worsening your exposure and spreading the contamination.

For a situation involving health symptoms and hidden growth behind furniture, a professional inspection is essential. They will assess the full extent of the growth, often using moisture meters and borescopes to see inside walls. In the UAE, look for a provider that can subsequently perform a lab analysis of a tape or air sample; this identifies the mold species and confirms the source, which is critical for an effective remediation plan and for your peace of mind. Proper remediation will involve isolating the area, removing contaminated porous materials like drywall, and HEPA vacuuming before the wall is repaired.
