AC leak causing black spots and stuffy nose: DIY or professional?« Back to Previous Page

A persistent AC leak causing black spots and a stuffy nose is a clear sign of active mold growth that requires immediate attention. In Dubai's high humidity, damp carpet backing and padding create an ideal breeding ground for mold, which is likely the source of your respiratory irritation.

A supermarket vinegar solution is insufficient for this scenario. It only addresses surface mold on non-porous materials, not the deep, established colonization within water-logged carpet fibers and the underlying pad. The AC unit itself may also be contaminated. Attempting a DIY clean often aerosolizes spores, worsening your exposure.

For a situation involving ongoing moisture, visible growth, and health symptoms, a professional assessment is strongly recommended. They will first stop the water source by identifying the AC leak's cause—often a clogged condensate drain line, which is extremely common here due to year-round operation and dust. The remediation process involves isolating the area, removing the affected carpet section and padding, HEPA vacuuming, and thoroughly cleaning the subfloor. A company with its own microbiology lab can then take tape or air samples to confirm the species and verify that the spore count in your bedroom has returned to a normal level, ensuring the problem is resolved.
