Black spots near leaking AC: DIY clean or call pro?« Back to Previous Page

Based on the description of a persistent leak, visible black spots spreading, and a strong damp smell, you should absolutely call a professional for an inspection. This is a serious case.

Leaking AC units in Dubai's climate create a perfect storm for mold growth. The constant humidity and condensation provide the moisture mold needs to thrive inside your walls and under the carpet, far beyond the visible spots. Bleach is a surface-level treatment; it cannot address the root infestation within porous materials like drywall and carpet backing. The damp, earthy odor is a key indicator that microbial volatile organic compounds (mVOCs) are being released, confirming active growth.

Attempting a DIY clean could aerosolize the spores, spreading the contamination throughout your bedroom and potentially your home's HVAC system. A certified mold remediation professional will first identify the moisture source, contain the area to prevent cross-contamination, safely remove the affected porous materials, and use specialized equipment like HEPA vacuums and air scrubbers to clean the air. For a case involving structural elements, professional assessment and remediation is the only way to ensure it is resolved safely and effectively.
