Why does my AC leak water every summer?« Back to Previous Page

In the UAE climate, this is an extremely common issue, and the recurring nature points directly to a clogged condensate drain line. When your AC runs, it pulls humidity from the air, and this moisture condenses on the cold evaporator coils. The water drips into a drain pan and is supposed to exit your villa through a PVC pipe. Dubai's intense dust and sandstorms mean this line gets clogged with a sludge of dust, microbial growth (like algae), and debris far more frequently than in other climates. When it's blocked, the pan overflows, leading to the puddle and damp wall you're seeing, especially during peak afternoon cooling cycles.

A simple unclogging is a temporary fix. For a permanent solution, you must insist the technician performs a comprehensive drain line hygienization. This isn't just a blast with nitrogen gas; it involves using a specialized vacuum truck and rotary jetting equipment to scour the pipe walls completely clean, followed by an EPA-approved biocide treatment to prevent immediate regrowth of the clog-causing microbes. They must also verify the drain pan's slope and check the primary drain line's P-trap, which is crucial for proper drainage in our high-rise villas.

Given the damp wall, a mold inspection is advisable to prevent indoor air quality issues, as per Dubai Municipality's public health guidelines. For a thorough, permanent resolution, I recommend calling our certified team at 800-MOLDS (800-66537) for a professional inspection and remediation. We guarantee our hygienization process will prevent this annual headache.
