AC leak caused mold, how to remove and clean ducts?« Back to Previous Page

A persistent AC leak with visible black mold and health symptoms requires a professional remediation plan, not a DIY approach. The moisture has likely penetrated the wall cavity, and standard cleaning will not address the root cause.

For a permanent solution, start with a professional inspection to assess the full extent of the mold growth inside the wall and the AC system. The remediation process typically involves isolating the area, removing contaminated porous materials like damaged drywall or insulation, HEPA vacuuming, and antimicrobial treatment of the structure. Simply wiping the surface is ineffective. Your AC unit and its internal drainage system must be repaired by a certified technician to stop the leak; this is the most critical step to prevent immediate recurrence.

Given your symptoms and the spread of mold, professional duct cleaning is strongly recommended. In Dubai's climate, AC systems run year-round, and a leak creates an ideal environment for mold to colonize the dark, damp ducts, continuously circulating spores throughout the room. The cleaning must be thorough, using methods like rotary brushing and negative air extraction, and should be verified with before-and-after testing to ensure the entire system is addressed. Look for providers who can document their process with lab analysis or imaging.
