Your aircon is not cold even after
servicing?
With Singapore homeowners suffering through
some of the hottest weather in recent years,
a well-functioning AC system is absolutely
necessary in order to combat the heat and
humidity. Most modern air conditioners last
for decades, but even the most managed
systems, at times, do not provide the air
that is cold enough to keep you and your
family comfortable.
An air conditioning system producing warm
air is never welcome, but this may not
necessarily be a serious problem. Sometimes,
even after getting your system properly
serviced, it produces warm air that makes
the atmosphere uncomfortable.

Here are the 4 most common reasons why
your air conditioner is producing warm air
in spite of being properly serviced.
Your condenser may have been damaged
Condenser is a part of an AC system in which
the refrigerant is converted back into
liquid. The condenser may sometimes get
frozen, if the system is dirty or run
inefficiently, and if the problem is not
treated immediately, the condenser may get
broken down completely. Although rare, a
damaged condenser is a serious problem and
cannot be solved without professional help.
Qualified HVAC technicians can fix the
problem of broken condense as well as tell
you when it's time to upgrade.
Your refrigerant might be low.
One of the common causes for air
conditioning system blowing hot air is the
shortage of refrigerant. This may also cause
ice to accumulate in the evaporator, because
the system never reaches the right
temperature and therefore never shuts off at
any stage. Periodic shutoffs when the
temperature is right for your room let the
ice melt in the evaporator, so little
refrigerant leads to a spiral of hot air and
ice on the evaporator. Regular maintenance
of your AC can eliminate this problem before
it happens, because an HVAC technician
checks the refrigerant level and makes sure
that everything in your system is working
properly.
Your condenser can be frozen.
The coil of the condenser is the part of the
air conditioning system that sits outside
the house. This coil is responsible for
removing heat from the inside of the house
and releasing it outside. If you have not
been getting regular maintenance of the HVAC
system, the dust, dirt and debris that is
collected by the filter can actually freeze
the coils and they may stop working
properly.
Mechanical problems
Many times during the summer, your air
conditioner can run all afternoon, if not
all day! This is hard for the mechanical
equipment present inside. Most of the time
fan motor of the outside unit goes bad, but
if you have a big problem the compressor can
be locked down as well. This is not good,
because the compressor is the core of the
system and the refrigerant cannot be moved
without it. Common repairs are done to
replace a bad fan motor, but sometimes you
need to replace the compressor.
Remember that regular maintenance is by far
the best way to prevent some of the problems
mentioned above. Regular maintenance keeps
your system in a fit and workable condition.
