AC leak causing wall mold: specialist or AC repair first?« Back to Previous Page

Based on your description, this is a classic and very serious issue in Dubai's climate. The constant AC leak has created a persistent moisture source, and the high ambient humidity provides the perfect conditions for mold to thrive, especially in concealed areas like behind curtains. The black spots are likely Stachybotrys chartarum or Aspergillus niger, both of which are health hazards and indicate a long-standing water problem.

You must address both the symptom (the mold) and the cause (the AC leak) simultaneously. However, the correct sequence is critical to prevent immediate regrowth and potential health risks.

Your first call should be to a certified mold inspection and remediation specialist, such as Saniservice. A professional assessment is non-negotiable. We will conduct a thorough inspection, including moisture mapping and air quality testing, to determine the full extent of the mold colonization, which is often far greater than what is visible on the surface. Our technicians are trained in the proper containment and removal protocols to safely eliminate the biohazard and prevent cross-contamination into your living space. DIY cleaning with bleach is ineffective and can exacerbate spore dispersal.

Immediately after the mold assessment, or concurrently, you must engage a licensed HVAC company to diagnose and permanently repair the AC unit. The leak is likely due to a clogged condensate drain line, a faulty drain pan, or incorrect installation/leveling – all common issues here. The AC technician must fix the leak at its source.

For a permanent solution, both specialists are required. The AC repair stops the water, and the mold remediation removes the contamination and restores the affected building materials. For immediate assistance with the inspection and safe removal, I strongly recommend you call our experts at 800-MOLDS (800-66537) or email hello@saniservice.com.
