Almost 90% of all household in
Singapore have an aircon system. Aircon in Singapore has
become a necessity rather than a luxury because it is a hot
and humid country throughout the year. When you walk to any
restaurant or shopping mall, you will encounter or feel the
presence of air conditioner. However, many Singaporeans do
complain that their air conditioner leak water often and
they have no idea on how to fix the problem. This article
focuses on the main causes on air conditioner leakages and
how to fit the problem.
The main function of an air conditioner
is to remove any moisture present in your house thus
providing a feeling of coolness. But through this process,
water is normally produced. The aircon normally produce
water depending on the moisture present in your room, the
size of the air conditioner, the working efficiency of your
air conditioner and lastly how your air conditioner was
installed. If you air conditioner was not properly
installed, there are very high chances that it will leak.
When the air conditioner sacks moisture from your room, the
moisture goes into the cooling compartment where it
condenses into the air conditioner base. The fan connected
to the aircon will lift the condensed water and channel it
to the pipe that connects the aircon to the outside where is
discharged to the ground through the pipe.
What are the main causes of
1. Broken pump.
When the condenser pump of your air conditioner is
broken, it will definitely start leaking water. You can test
this by first poring water into the condenser pan and see if
can properly pump out the excess water. If it can’t then the
condenser pump is broken or it not functioning to its full
2. Improperly installed.
When the aircon unit improperly installed, it can easily
leak water. If there is too much pressure on the unit or if
the unit is not level, water may begin to pool.
3. When the drain hole is blocked.
Every air conditioner has a drain hole that removes
water form the unit. Sometimes the drain hole can be blocked
with debris or dirt thus blocking the passage of water.
4. When the outside temperature is
When the outside temperature starts to change, you can
actually end up with extra water buildup due to temperature
imbalance. For instance, when the outside temperature is too
cold, it will cause water to star building around the unit
making a pool simply because the water is unable to
5. Air leakage.
If the seals of the air conditioner are not tight
enough, excess warm air can find its way inside the unit.
This causes the moisture from the air to condense when it
comes into contact with the cold air that is inside the air
conditioner. The excess moisture will star forming pools
below the unit. Pooling water is the worst thing that can
happen to any air conditioner. If water is pooling on your
air conditioner, then the unit is not functioning properly
and that means that will not get the temperature that you
want in your house.
How can you fix aircon leaking
When it comes to fixing a leaking air
conditioner, there are few crucial aspects you need to
consider. Normally, there are 4 common reasons for this
specific problem ant they include: dirty filters, blocked
drains, shortage of refrigerant and improper installation.
1. Dirty filters
When the filter of the heat exchanging coils is unclean,
then it can actually lead to restricted air flow. The
restricted flow of air can cause the temperature of the coil
to decrease thus making the moisture present in the air to
freeze up thus creating small ice flakes which eventually
causes water leakage when the water melts. To fix this
problem, you first need to check the filter. If the filter
is grimy, use a horse pipe to properly clean all the dirt.
On the other hand, if the filter is filled with a lot of
dirt and grim, use a backyard spray bottle or a sturdy
kitchen cleaner to remove the dirt. The air flow of your air
conditioner will greatly improve if the grim or the dirt
that has accumulated is removed and it will prevent the
aircon from leaking if that was the cause of the problem.
2. Blocked drain
As mentioned earlier, blocked drained is another big
problem that could cause the aircon to leak. If the drain is
clogged, water may leak from the back of the unit or through
the aircon outlet. To fix this problem, thoroughly check the
air conditioner by standing on a small ladder. Thoroughly
inspect the little tray under the heat exchanger that is
normally used to collect the condensed water generated
through the cooling mode of the aircon. Make sure that the
tray is not overflowing or full. Also clean the end of the
pipe outside to clear any sort of blockages. If you can’t
clear the blockage by yourself seek assistance from
professionals to help you right away.
3. Refrigerant loss
When the heat exchanger and air filter are working to
full capacity, your air conditioner must be able to provide
plenty of cool air. If the unit is not able to provide
enough cooling air into the house and then the aircon begins
to leak, there must be something wrong with the refrigerant.
To fix that problem, you need to first change the setting of
the heat pump to the lowest level and allow it to run that
way for some time. Then check the heat exchanging coils
located under the filter. If the coil is covered with ice,
then your aircon has a water leakage and need to be
repaired. If you can’t fix the problem buy yourself, contact
the local air condition company to fix the problem for you.
4. Correct installation
The air conditioner can start leaking if it not properly
installed. To fix this problem, check to see if the unit is
in level. If it is in level, go ahead and look for any
closed vents in the house. This is because the closed vent
can sometime add pressure causing the valve to leak. If you
are not able to fix the problem by yourself, call a
professional to fix the problem for you.
