AC leak on carpet, how to dry and prevent mold?« Back to Previous Page

The damp smell is a strong indicator that moisture has already penetrated beyond the surface, likely into the carpet padding and potentially the subfloor. Your concern is valid, as the high humidity in Dubai creates an ideal environment for mold to establish itself within 24-48 hours in damp conditions.

Your first and most critical step is to call building maintenance immediately to repair the AC leak. This is the source of the problem, and no amount of drying will be effective if water continues to seep in. They are responsible for fixing the unit itself.

For the wet carpet, surface drying is insufficient. You must lift the wet section of the carpet away from the wall to expose the soaked padding beneath. Carpet padding acts like a sponge and will hold moisture against the concrete slab, leading to mold growth you cannot see. The padding will likely need to be removed and discarded. Use fans and a dehumidifier (not just an AC) directly on the exposed floor and the back of the carpet for at least 24-48 hours to draw out all residual moisture. Simply drying the visible top layer is a common mistake.

Given the persistent smell and the likelihood of hidden moisture, a professional inspection is strongly advised. They use moisture meters and thermal imaging cameras to find dampness within walls and under floors that are not apparent. If mold is suspected, only a lab test can identify the type and concentration, which dictates the correct remediation method. In many Dubai apartments, this hidden growth is the real issue, not just the visible leak.
