Can I clean AC mold with bleach or call professional?« Back to Previous Page

The AC in my apartment seems to be leaking a little water onto the carpet in the bedroom, and now I’m spotting these small black patches around the edge. It’s been humid lately and I’m worried it’s spreading. Is this something I can tackle myself with bleach from the supermarket, or do I need to call in a professional cleaning company?

Based on my professional experience in mold inspection and remediation in the UAE, I strongly advise against using bleach to clean mold from your AC system or the affected carpet. Bleach is ineffective on porous materials like carpet fibers and drywall, as it only removes the surface discoloration while leaving the root mold structure intact. Furthermore, the high water content in bleach can actually exacerbate the problem by adding moisture, promoting further mold growth in Dubai's humid climate.

The situation you've described—AC leakage leading to damp carpet and visible black patches—is a serious concern. This indicates a persistent moisture source, which is the primary catalyst for mold proliferation. In our environment, where air conditioning runs year-round, condensation and internal leaks are common. Attempting a DIY clean not only risks inadequate removal but also poses significant health hazards from disturbing and aerosolizing the spores.

For a situation like this, a professional inspection is not just recommended; it is essential. Our certified technicians use specialized equipment, such as moisture meters and thermal imaging cameras, to identify the full extent of the water intrusion and mold colonization, which is often hidden within the AC unit itself, behind walls, or under carpets. Remediation involves containing the area, using HEPA filtration to capture spores, and applying EPA-approved antimicrobial agents designed for porous materials, followed by addressing the root cause of the AC leak.
