How to fix AC leak and clean mold in JVC?« Back to Previous Page

The situation you're describing in JVC is a classic and very common issue in Dubai's climate. The persistent high humidity and year-round AC operation create a perfect storm for condensation-related problems. The black spots on your skirting board are almost certainly mold, a direct result of the moisture from the AC leak.

Your first and most critical step is to stop the moisture source. Do not attempt to clean the mold until the leak is resolved, as it will simply return. The AC leak could be due to a clogged condensate drain line, a damaged drain pan, or improper installation/insulation of the drain line. This requires a certified HVAC technician. In the UAE, all AC maintenance and repair work should be conducted by technicians holding a valid permit from the Dubai Municipality's Climate Control Department (or the relevant local authority) to ensure compliance with health and safety standards.

For the mold, a small, surface-level growth on a non-porous material like a skirting board can sometimes be addressed by carefully wiping the area with a solution of detergent and water, followed by a diluted bleach solution (1 part bleach to 10 parts water), ensuring adequate ventilation. However, this is only a temporary surface measure. The moisture may have already wicked into the porous carpet and the wall behind the skirting board, harboring hidden colonies that will continue to grow and release spores.

Given the high humidity and the potential for hidden growth, a professional inspection is strongly recommended. We use moisture meters and thermal imaging cameras to assess the full extent of the water damage and mold colonization within the building materials. Proper remediation involves containing the area, removing contaminated porous materials like wet carpet sections or drywall, and using industrial-grade HEPA filtration and antimicrobial agents to ensure the problem is eradicated at its source.

For a permanent solution to both the AC leak and the resulting mold, I advise calling a professional HVAC technician to fix the unit and a certified mold remediation company like Saniservice to handle the biological contamination.
