Mold from AC causing headaches; what's the first step?« Back to Previous Page

Yes, that combination of a leaking AC, visible black mould, and symptoms that improve when you leave the room strongly suggests your headaches and congestion are mould-related. The constant moisture from the drip creates an ideal environment for mould growth, and the AC unit then aerosolizes the spores, circulating them throughout the bedroom air you breathe all night.

Your first step is to stop the moisture source. Have an HVAC technician repair the AC leak immediately; this is non-negotiable. In Dubai's climate, with high humidity and year-round AC use, a small leak rapidly escalates into a significant mould problem behind walls and in ceiling cavities.

Do not attempt to clean the visible mould yourself with bleach or store-bought sprays. Disturbing it without proper containment will release a high concentration of spores into your living space, potentially worsening your symptoms and contaminating other areas. For widespread growth, especially on porous materials like drywall, professional remediation is required to safely remove the affected materials and implement engineering controls like negative air pressure.

Given the health symptoms, a professional inspection is advised to assess the full extent of the hidden growth behind the wall and wardrobe. A reputable inspector will use tools like moisture meters and borescopes and can recommend a lab test to identify the mould species, which helps determine the appropriate remediation protocol. Focus on companies that provide verifiable, documented evidence of the problem and the solution, not just a visual cleaning.
