Is AC condensate causing ceiling leak?« Back to Previous Page

After the rain last month, I noticed water seeping through the ceiling in the living room at night. The AC unit is installed directly above that area, and every time it turns on, there’s a loud dripping sound. It seems like the condensate drain might be clogged or not properly sloped. How can I check if this is causing the issue and what steps should I take to prevent water damage?

Is AC condensate causing ceiling leak?

When experiencing a dripping sound and water seeping through the ceiling directly below an air conditioning unit, it's highly probable that your issue is linked to improper drainage of the condensate. The UAE building codes require proper installation and maintenance of HVAC systems, including correct condensate disposal. For this situation, I would recommend taking some immediate steps before considering professional assistance.

Firstly, check if the condensate pan and drain are properly sloped towards an external drainage system or a suitable interior location that can handle water runoff without causing damage. The slope should be at least 1/4 inch per foot to ensure proper flow. If your unit is installed directly above the leaky area, it's possible that the slope isn't adequate, leading to the condensate pooling and eventually dripping through the ceiling.

To inspect this:
• Turn off the AC system and locate the condensate pan beneath the indoor unit.
• Inspect for any signs of water accumulation or discolored areas indicating moisture damage.
• Check if the drain line is connected correctly and ensuring there are no kinks, blockages, or leaks.

If you find that the slope isn’t sufficient or the drainage system is blocked, you may need to adjust the pan's angle or clear any clogs in the line. However, if this doesn't resolve your issue, it’s advisable to contact a certified HVAC technician for an inspection and repair.

In Dubai/UAE, the building regulations stipulate that all AC units must be installed by licensed professionals who adhere to specific guidelines set forth by local authorities such as the Department of Economic Development (DED). A professional can assess whether there are any other underlying issues like faulty seals or insulation problems contributing to water intrusion.
