What's the permanent fix for recurring AC leak and mold?« Back to Previous Page

The recurring leak suggests the initial repair didn't address the root cause. In Dubai's high humidity, this persistent moisture will always lead to mold regrowth.

A permanent fix requires a systematic approach. First, the AC unit's drain line must be professionally cleared and pressure-tested to ensure it's completely unobstructed, not just temporarily unclogged. The drain pan should be inspected for cracks and the unit's slope verified; even a slight misalignment can cause water to back up. For the existing mold, surface cleaning is insufficient. The damp carpet, padding, and affected wall material likely harbor deep fungal growth that must be physically removed to prevent spores from spreading.

Given the mold is already on personal items like shoes, a professional inspection is strongly recommended to assess the full extent of contamination behind walls. They can use moisture meters and borescopes to find hidden dampness. The long-term solution involves not only a complete mechanical repair of the AC system but also remediation of all affected porous materials and addressing the humidity in that enclosed closet space to prevent future condensation.
