AC leak causing black spots and smell: urgent professional needed?« Back to Previous Page

Yes, you need a professional inspection immediately. A two-month leak with visible black spots and a persistent earthy smell strongly indicates active mold growth, likely inside your wall cavity. The Dubai climate accelerates this problem; high humidity and constant AC use create ideal conditions for mold to thrive behind surfaces.

The leak itself is a secondary issue to the microbial growth it has caused. A proper inspection involves more than a visual check; it requires moisture mapping with thermal cameras and hygrometers to locate all affected areas, and air/surface sampling to identify the mold species. Some species common in AC-related leaks, like Cladosporium or Stachybotrys, require more aggressive containment protocols during remediation.

Do not attempt to clean this yourself. Disturbing the mold without proper containment can aerosolize spores and spread the contamination throughout your home's air system. A professional assessment will define the full extent of the problem and create a remediation plan that follows Dubai Municipality guidelines for indoor air quality and mold removal. Addressing it correctly now prevents a much larger and more costly problem later.
