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

The AC in my bedroom has been leaking a bit for a couple of weeks, and now I’m seeing these small black spots spreading on the wall behind the curtain. It’s in a corner so I didn’t notice it right away, and the room has started to feel a bit damp. Is this something I can clean myself with bleach, or do I need to call a professional company to deal with it?

Based on the symptoms you've described—AC leakage, persistent dampness, and the emergence of black spots on a concealed wall—this is a situation that warrants immediate professional attention. In Dubai's climate, where high humidity and constant AC use create a perfect environment for mold, what you see on the surface is often just the tip of the iceberg. The moisture from the leaking unit has likely saturated the wall cavity, promoting growth within the structure itself.

Using bleach is strongly discouraged. It is ineffective on porous surfaces like drywall and plaster, as it only bleaches the surface mold without addressing the root colony. More critically, bleaching can aggravate the problem by releasing a high volume of spores and toxic vapors into your living space, potentially causing severe respiratory issues.

The correct protocol involves first stopping the moisture source—the AC leak must be repaired by a certified HVAC technician. Then, a certified mold inspector should conduct a thorough assessment, including moisture mapping and possibly air quality testing, to determine the full extent of the contamination. Remediation is not a simple cleaning; it requires isolating the area, using HEPA filtration to capture airborne spores, and safely removing and disposing of contaminated porous materials.

For a comprehensive inspection and remediation protocol that adheres to Dubai Municipality's strict health and safety guidelines, I recommend contacting the professionals at Saniservice. They can provide a definitive diagnosis and a safe, effective solution. You can reach them at 800-MOLDS (800-66537) or via email at hello@saniservice.com.
