How to clean AC leak mold and who fixes it?« Back to Previous Page

First, stop the moisture source immediately. Turn off that AC unit to prevent further leaking and mold growth. The black speckles are likely mold colonies feeding on the damp carpet. For a small area (under one square meter), you can clean it yourself with proper precautions.

Wear an N95 mask, gloves, and safety glasses to avoid inhaling spores or skin contact. Scrub the visible mold off the carpet fibers with a stiff brush and a solution of detergent and warm water. After scrubbing, use a wet-dry vacuum to extract as much moisture as possible. Then, thoroughly dry the area with fans and a dehumidifier; in Dubai's humidity, this drying step is critical and may take 24-48 hours. Do not use bleach, as it can discolour surfaces and doesn't prevent regrowth.

However, this only addresses the visible surface mold. The carpet backing and padding underneath are likely saturated and harboring deeper contamination, which is almost impossible to fully clean and dry. In many cases, the affected section of carpet and padding must be cut out and discarded to properly resolve the issue.

To stop it from coming back, you must fix the AC leak. This requires a certified HVAC technician. The leak is likely due to a clogged condensate drain line—extremely common here due to dust and humidity—or a faulty condensate pump. A general handyman might not solve the root cause. Hire a licensed HVAC company to clear the drain line, check the pump, and ensure the unit is levelled correctly to allow proper drainage.

For peace of mind on the mold, especially in a bedroom, a professional inspection can confirm the extent of growth and that it has been adequately remediated. In villas, a small leak can sometimes lead to mold in the AC unit itself or subflooring, which requires specialist assessment.
