Should I clean AC mold myself or call a professional?« Back to Previous Page

The AC in my bedroom closet has been leaking a little for a couple of months and now I’m seeing black spots spreading on the back wall and on some of my shoes. The musty smell is really strong when I open the door. Is this something I can clean myself with bleach spray or do I need to call a professional company to deal with it?

Based on the symptoms you've described—ongoing AC leakage, spreading black spots, and a strong musty smell—this is a clear case of active mold growth that requires professional attention. In Dubai's high-humidity climate, AC units are a primary source of condensation, creating the perfect environment for mold to thrive, especially within enclosed spaces like closets.

Attempting a DIY clean with bleach is strongly discouraged. Bleach is ineffective on porous materials like drywall and shoe leather, as it only bleaches the surface mold without addressing the root colony. More critically, agitating the mold during cleaning can release a high concentration of spores and mycotoxins into your bedroom's air, posing a significant health risk and potentially contaminating other areas of your home.

UAE regulations, particularly from Dubai Municipality, emphasize the importance of proper mold remediation to protect indoor air quality and building integrity. A professional company will first conduct a thorough inspection to identify the full extent of the infestation, even within the AC unit itself and the wall cavity. The remediation process involves containment of the area, specialized HEPA filtration to capture airborne spores, and the use of professional-grade antimicrobial agents to eliminate the mold at its source, followed by addressing the moisture issue to prevent recurrence.
