AC leak causing mold in closet: urgent health risk?« Back to Previous Page

The AC in my apartment seems to be constantly leaking water into the closet where the unit is housed, and now I’m seeing black spots spreading on the wall behind our winter clothes. It’s been like this for about three weeks but has gotten worse since the humidity spiked. With summer coming, we’ll be running it 24/7, and I'm worried about my family's health. How urgent is it that I get a professional mold removal company in Dubai involved, and is this something I can temporarily clean myself until they arrive?

This situation requires immediate professional attention. The combination of constant moisture from the AC leak and Dubai's high humidity creates an ideal environment for mold, which is likely growing inside the wall cavity where you cannot see it. The black spots are a visible sign of a potentially larger, hidden problem.

For your family's health, this is urgent. Prolonged exposure to mold spores, particularly from the types that thrive in damp AC systems and building materials, can cause respiratory irritation, worsen allergies, and trigger asthma attacks, especially with 24/7 AC use imminent.

Do not attempt a significant cleanup yourself. Disturbing the mold without proper containment can aerosolize a high concentration of spores throughout your apartment. You can take temporary measures: stop the leak at its source by turning off the AC unit and contacting an HVAC technician to address the drainage issue—this is the critical first step to stop the moisture. Carefully remove the winter clothes from the closet and wash them to prevent spore transfer.

For the remediation itself, a professional company is essential. They will follow Dubai Municipality guidelines for containment, use HEPA filtration to capture spores, and safely remove contaminated materials. The most critical step they provide is identifying the moisture source and verifying its resolution to prevent rapid regrowth. After remediation, a post-testing protocol is the only way to confirm the air quality is safe.
