Reasons for Your Aircon (AC) Unit Breaking Down
Most houses these days are equipped with air conditioners to help
beat the heat of humid Malaysia. However, often, households tend not
to pay attention to their aircon units until there's a breakdown.
Several problems could cause your air conditioner to underperform.
What are common problems with air conditioners?
Some common problems you would face with an air conditioner are
water leaking, warm air, strange smells or weird noises coming from
your unit. Other common problems are air-cond units not constantly
turning on or tripping up the circuit breaker.
What causes the air conditioner to freeze up?
Air conditioners can freeze up when clogged air filters block the
airflow. The lack of constant airflow will allow humidity to settle
on the coils and freeze them up. Air conditioners could also get
frozen because of a leak with the coolant or a low-quality
Common reasons for aircon breakdown
The stress of frequent use causes a breakdown in your air
conditioning system, and these are some of the common reasons you
would need to schedule a repair service.
Every aircon unit needs a specific amount of refrigerant to
cool down temperatures efficiently. Refrigerants would not
usually deplete unless there is a crack resulting in leakage.
This will cause humidity and temperatures to rise.
Often, it is better to have a professional switch it out for a
new refrigerant rather than attempting to repair the leak.
Air filters are supposed to keep contaminants out of your AC
unit. However, when it's clogged up with dirt and dust, it
won't be able to do its job well. In addition, the restricted
airflow and built up dust will start to cause harm to the
other components of your AC unit. So clean out your air
filters monthly to ensure that your unit is working
efficiently. If you’re wondering how to clean aircon filter,
we suggest to leave it to the
aircond servicing professionals .
A dirty air filter prevents sufficient airflow and causes a
layer of frost to develop on the evaporator coil that
eventually freezes up. When this happens, the rest of the
components have to work harder to compensate for the
The evaporator and condenser coils are also used to transfer
hot and cold air between the outdoors and your home. If they
are dirty or frozen and cannot work correctly, it will
increase the temperatures within your house, making it
Like all electronics, components tend to go through the
process of wear and tear over time. As parts get old, they are
likely to break down and are unable to function optimally.
Scheduling regular maintenance allows your technician to make
sure the components are working well and replace any broken
Keeping all the components of your air conditioning unit clean
is key in getting it to work efficiently. Fans also operate to
transfer hot and cool air between your home and the outdoors.
Excess dirt on the blades will get it to start working harder
and, in turn, damage the motors quickly. If the outdoor fan is
broken, it can also cause your unit to overheat. Check your
fans regularly and clean them of dust between your scheduled
The aircon can be underperforming not because there's any
fault within the unit, but the thermostat is faulty. Minor
issues with your thermostat would require a battery change or
the settings to be adjusted. For example, a defective
thermostat would set the cycles to turn on and off more
frequently, which would make it seem like the unit is broken.
Reasons for aircon leaking water
There are a couple of reasons why your aircon could be leaking
water. First, a condensation drain line can be clogged by dirt, dust
or mold, making it challenging to get drained out; the water then
collects and starts leaking into your home.
Sometimes, the water leakage comes from a frozen coil melting when
the air conditioner freezes. It could also be a broken condensate
pump or a rusty drain pan, typical in older aircon units.

Why is my AC running but not cooling?
If your AC is blowing air that's not cold, it could be a simple
issue with the air filter or the thermostat being set wrongly. These
issues can be resolved simply by cleaning out the air filter or
turning the fan setting to Auto.
More severe issues include refrigerant leakage causing your AC not
to cool down. Again, this is an issue best resolved by a
professional. Besides this, it could be an issue with your
evaporator coil freezing.
There are quite a few reasons for your air conditioner to break
down. Keeping the components related to airflow clean and dust-free
will save your AC unit from breaking down frequently and operating
at optimum levels in between service appointments.
It is best not to attempt to repair your air conditioner on your own
because there are many sensitive components in the unit. Instead,
to assess the problem and perform the
air conditioning cleaning
for you. Sometimes it could require aircon chemical cleaning as the
solution. Reach out to the team at
for reliable and quick consulting if your AC is having problems.
