AC leak causing black spots: DIY fix or call professional?« Back to Previous Page

Given the AC leak and visible black spots, this likely requires professional assessment. Dubai's high humidity and constant AC use create ideal conditions for mold to grow not just on surfaces but within walls or under carpets where a DIY approach can't reach.

While small surface mold can sometimes be treated with a vinegar solution, an ongoing leak means the moisture source isn't resolved. Spraying bleach only removes surface discoloration and doesn't address the root cause or hidden growth. The leak itself needs to be fixed by an AC technician first.

For your situation, a professional inspection is advised because the leak has been ongoing. They use moisture meters and thermal cameras to detect hidden dampness in walls and under flooring that isn't visible. In many Dubai villas, this hidden moisture leads to structural damage if left untreated. A proper inspection will define the full extent of the problem and identify the mold species, which determines the required remediation approach.

You can start by immediately stopping the leak and drying the area. However, for a confirmed and lasting solution, a diagnostic inspection is the most reliable course of action.
