How to permanently fix AC leak and treat black mold?« Back to Previous Page

The AC leak is the root cause, and until it's fixed, the mold will return. In Dubai's high humidity, this creates a perfect environment for mold growth. You need two separate professionals: an HVAC technician to fix the leak and a mold remediation specialist to handle the contamination.

For the AC leak, call a licensed HVAC company. The issue is likely a clogged condensate drain line, a faulty drain pan, or improper installation/insulation causing condensation. A proper fix involves clearing the line, ensuring correct slope for drainage, and sometimes replacing components. They should perform a full system check to prevent future leaks.

For the mold, wiping with bleach only removes surface discoloration; it doesn't kill the roots (hyphae) penetrating porous materials like drywall. The hidden mold inside the wall cavity is the real concern. Effective remediation requires isolating the area, removing contaminated materials like the affected section of drywall and carpet padding, and using specialized antimicrobial treatments. A company with its own microbiology lab can provide before-and-after testing to verify the spore count has been returned to safe levels, which is the only way to confirm it's truly gone.

Address the leak first to remove the moisture source, then proceed with remediation. For a situation involving structural materials, a professional inspection is strongly recommended to assess the full extent.
