Mold from AC causing my health symptoms?« Back to Previous Page

The AC in my bedroom has been leaking a bit for a couple of months, and now I’ve found black spots on the wall behind the curtain. Lately, I’ve been waking up with a stuffy head, a sore throat, and feeling really tired. Is it possible these symptoms are connected to the mold, and what’s the first thing I should do to handle it safely?

Yes, your symptoms are very likely connected to the mold growth from the AC leak. The constant moisture from a leaking unit, combined with Dubai's high humidity, creates an ideal environment for mold. Exposure to its spores while you sleep commonly causes the exact issues you're describing: morning congestion, sore throat, and fatigue, as these are classic signs of mold-related irritation.

The first step is to stop the moisture source. Have an HVAC technician repair the AC leak immediately. For your safety, do not attempt to clean the black spots yourself, as improper scrubbing can aerosolize a high concentration of spores. Instead, isolate the area by keeping the curtain closed and the door to the room shut to prevent spore spread.

Given the symptoms have persisted for months, a professional inspection is strongly recommended. They can assess the extent of the growth, which may have spread into the wall cavity behind the visible spots. A proper remediation plan, not just surface cleaning, is often needed to resolve the issue. In the UAE, look for providers who follow international guidelines like IICRC S520 and can provide post-remediation verification to confirm the environment has been returned to a healthy state.
