How to permanently kill AC mold and fix the leak?« Back to Previous Page

Bleach only removes surface mold you can see; it won't kill the roots or address the dampness inside the AC unit causing it. The leak is the primary issue—until that's fixed, mold will return.

First, call a licensed HVAC technician to repair the condensation leak. Common causes in Dubai's climate are clogged drain lines from dust, improper installation, or a damaged drain pan. They should seal the unit properly and ensure the drainage system is clear and sloping correctly.

For the mold, the carpet and underlying padding are likely contaminated. Professional remediation is needed to remove the affected section, treat the subfloor, and install new materials. A company with a microbiology lab can take samples to identify the species, which dictates the correct antimicrobial treatment for a permanent solution.

Given the high humidity, simply drying the area isn't enough. After fixing the leak and removing the mold, using a dehumidifier in the room for a few days can help bring moisture levels down to prevent recurrence. For a situation involving an AC leak and visible growth, a professional inspection is recommended to assess the full extent.
