Could my AC leak and wall mold be making me sick?« Back to Previous Page

That combination of an AC leak, visible black growth, and your specific symptoms is a strong indicator that mold is the likely cause of your sinus and respiratory issues. The constant moisture from a leak creates the perfect environment for mold spores, which are always present in the air, to colonize and spread on porous surfaces like drywall.

The Dubai climate exacerbates this; high humidity provides ample moisture, and our year-round AC use means any internal leak becomes a continuous water source. The black spots are a significant concern, as several species of mold that appear black can produce mycotoxins and irritants that directly affect respiratory health, leading to the exact symptoms you describe—persistent sinus congestion, coughing, and general irritation.

You should treat this as a serious issue. Do not attempt to clean it yourself with bleach, as this can agitate the spores and worsen your exposure without addressing the root problem inside the wall. The first step is to stop the moisture source: have an HVAC technician repair the AC leak immediately.

Following the repair, a professional mold inspection is highly recommended to assess the full extent of the hidden growth behind the wardrobe and wall. Proper remediation involves containment, safe removal of contaminated materials, and HEPA filtration to clean the air. For health confirmation, a lab analysis can identify the specific mold type, which helps in understanding the potential risk level. Resolving the underlying moisture problem is the only way to ensure it does not return.
