AC Leaking Again: Best Coil Cleaning Schedule in Dubai?« Back to Previous Page

A leaking AC in an older Al Barsha villa is almost certainly due to a clogged condensate drain line caused by dirty evaporator coils. The intense Dubai heat, year-round operation, and high dust load mean coils accumulate grime much faster than in milder climates. This sludge mixes with condensation, blocks the drain pan, and causes the water leak you're seeing, while also reducing cooling efficiency.

For a villa in this environment, an annual service is the absolute minimum. However, with an older unit that's already showing symptoms like reduced cooling and recurring leaks, a more frequent schedule is necessary. A professional coil cleaning every 6-9 months is a common preventative measure to maintain performance and prevent water damage. The critical factor is the initial inspection; a technician must fully disassemble the unit to access and properly clean the coils and, most importantly, flush the drain line with a pressurized jet to clear the organic buildup completely.

Simply topping up gas or wiping exterior surfaces won't solve the root cause. After a proper cleaning, you should notice a measurable improvement in cooling and humidity control. For persistent issues, the problem may be more complex, such as a misaligned drain pan or a deeper blockage, requiring a more thorough diagnostic approach.
