Question

I have clean my home wall mounted aircon drain pan. It seems water is draining out as usual, no blockage. When I turn off my AC, I still notice a few water drops out at fan blades. What seems to be the problem?

Answer 1

If you notice water drops coming out of the fan blades of your wall-mounted air conditioner after turning it off, there might be a couple of reasons for this issue:

1. Condensation: Air conditioners remove humidity from the air as they cool it, and this excess moisture condenses on the evaporator coils. Typically, the condensed water drips down into the drain pan and is then drained away through the drainage system. However, sometimes a small amount of condensation can accumulate on the fan blades or other parts of the unit before it is drained away completely. This can result in a few water drops dripping from the fan blades after the AC is turned off. While this can be normal to some extent, excessive water droplets may indicate an issue with the drainage system.

2. Improper Drainage: Even if you've cleaned the drain pan and checked for blockages, there might still be a minor drainage issue. The drainage line or drain pan might not be perfectly leveled, leading to residual water in certain parts of the unit. Over time, this can cause a small amount of water to accumulate and drip from the fan blades when the AC is turned off.

To address this issue, you can try the following:

1. Check Drainage System: Double-check the drainage system to ensure there are no blockages or obstructions. Make sure the drain pan and the drainage line are clean and properly connected.

2. Level the Unit: If the unit is not perfectly leveled, adjust its position to ensure proper drainage. This may require the help of a professional technician.

3. Inspect the Condensate Pump: Some wall-mounted air conditioners have a condensate pump to help drain the water. If your unit has one, make sure it is functioning correctly.

4. Regular Maintenance: Ensure you perform regular maintenance on your air conditioner, including cleaning or replacing the filters as needed, to maintain efficient operation and reduce the chances of drainage issues.

If the problem persists or worsens, it's best to have a professional HVAC technician inspect your air conditioner. They can identify any underlying issues and provide the appropriate solution to prevent water leakage or any potential damage to the unit.
