Why is your Aircon leaking water?
Drainage pipe choke.
If water is leaking from the Aircon unit itself. It would most definitely be due to a congested drainage pipe. In these instances, the water leakage will likely appear from the front of the ac unit, near the flap. It will usually appear as a gush of water dropping from the flap. Usually, this form of leaking will not appear as droplets. You would be able to hear water dripping onto your floor board. If you are unsure if this is the issue. You could also pour water into the fancoil. That is right, you will not hurt your Aircon by doing so. If the water didn’t get absorb by the drainage pan. It will immediately cause an outflow of water. All of the water that you pour into the evaporator coil will end up on your floor.
Aircon leaking water due to Congested back tray.
This is a problem that is much harder to identify. If you see water droplets dripping down from the back of your aircon. This could be an indication of a congested brack tray. In the past, air-conditioners used to be longer in vertical length. This evaporator coil is flat. All of the condensation form on the evaporator coill will drip onto the drainage pan. However, design is a bigger factor for the outlook of an indoor fancoil unit now. The design is now an inverted V shape. That means that part of the condensed water will flow towards the back of the Aircon. In air-conditioning term, we call it as backtray. Over time, the water accumulated from the evaporator coil will clog up the backtray. Hence, water still start dripping from the back of the fancoil unit.
Condensation of your copper pipes.
How do you know if your copper pipes have condensation issue? If you are living in a hdb flat. You can most likely see the trunking of your Air-conditioners. Take a look and observe if there are moisture forming on the trunking exterior. If you trunking is white, and you see black patches forming. It could be Aircon condensation problem. The reason for condensation of the copper pipes could be due to worn out Armaflex insulation. It could also be changing of new Air-conditioners. Inverter Aircon have a much higher gas pressure than non-inverter Aircon. Hence if you change into a newer aircon, you might need better aircon installation materials. The armaflex insulation used in the past is most likely ⅜ inches. However the upgraded materials used these days are ½ inch in thickness. This extra thickness will have a stronger layer of protection from condensation issue. Water leaking from the copper pipes is a serious issue that will require major work to rectify. There’s a few immediate solution to solve this problem temporarily as outline below.
Loose water hose
Another reason that might leak to aircon leaking water will be loose connection of water hose. If you just had your Aircon serviced recently, you will likely encounter this problem within 24 hours of it. That is because the technician has likely been careless in tightening the Aircon hose and drainage pipe. We would advise you to call up the Air-conditioning technician to rectify this issue. (P.S, we are guilty of this from time to time as well)

Hence, your bet is to prepare those pails to contain the dripping water, and call us up for an Aircon servicing appointment to rectify your issue.
Solutions to Aircon Dripping water

Tape a few pieces of cloth onto your wall
If aircon dripping water is caused by clogged backtray or loose water hose. You will likely have water dripping onto the back of your wall. You would not water this flow of water to slowly drip from your water to your floor. Overtime this could cause damage to both your wall and your floodboard. What you can do is tape a few pieces of cloth onto your wall. This will absorb the flow of water that is dripping water down from your wall. As listed above are only temporary solutions. For congested backtray, you might require to do a full chemical overhaul to prevent it from choking again. Because you will need to dismantle the entire fancoil to access the backtray section. If the leaking issue is due to loose water hose, you will have to call the Aircon technician down to reattach back the hose.
Identify the fan speed and wash your aircon filter.
This solution is only applicable for aircon leaking water due to condensation issue.
First, identify the fan speed of your Aircon. Do not turn it on Auto mode. A general rule for Aircon maintenance is, always turn it to maximum fan speed. This will result in lower pressue in the copper pipes, hence less condensation. Therefore, check your remote control and turn it to maximum, monitor the situation from there. Note : you might have to wait for a while for the insulation inside the casing to dry up first before you turn on the Aircon again.
Second, check your Aircon filter. A dirty Aircon filter or dirty coil will result in Aircon condensation as well. As the air will be prevented from coming out from the coil, resulting in pressure build up in the copper pipes. So if your Aircon filter is dirty, you can try washing the filter and see if there’s any changes to the condition. If your Aircon is dirty, it might be time for you to call us up for an Aircon Servicing appointment.
