How to permanently stop AC leak and mold in Jumeirah?« Back to Previous Page

Your leak is likely a symptom of a larger issue, not the root cause. In Dubai's high humidity, recurring AC leaks are almost always due to one of three problems: a clogged condensate drain line, a damaged or misaligned drain pan, or insufficient insulation on the cold refrigerant lines causing excessive condensation.

Simply fixing the visible leak and wiping the mold is a temporary fix. The mold you see on the skirting board is just the surface growth; its root structure (mycelium) is likely deep within the damp drywall and carpet backing.

The definitive long-term solution requires a systematic approach. First, a qualified HVAC technician must permanently resolve the water source. This isn't just a maintenance handyman task; it requires diagnosing the specific failure point in the AC system, which often involves using a vacuum to clear the algae-clogged PVC drain line or replacing a cracked drain pan.

Second, the existing mold and water-damaged materials must be properly remediated. For porous materials like carpet, carpet underlay, and water-soaked drywall (skirting board and potentially the wall behind it), complete removal and disposal is the only way to ensure all hidden mold is gone. Surface cleaning will not eliminate it. The area must then be thoroughly dried using professional-grade dehumidifiers and air movers, not just waiting for it to air dry.

Finally, to prevent recurrence, ensure your AC unit is correctly sized for the space and is running on a low fan speed setting to maximize dehumidification. Consider applying an anti-microbial coating to the new drain pan and lines to inhibit future algal growth.

Given the recurring nature and visible mold, a professional inspection that includes moisture mapping is strongly recommended to assess the full extent of the damage hidden within the wall cavity. This is a common issue in JVC due to the climate, and a proper fix now will prevent ongoing health irritants and potential structural damage.
