Intro
If youve ever spent a hot summer in India in a
home or business plagued with air conditioner
problems, its certainly an experience you
dont want to repeat. Dont leave your summer
comfort to chance! Learn about the most common
causes of air conditioner problems and the easy
steps you can take to prevent repair issues.

1. LOW REFRIGERANT
The refrigerant is the stuff that your
air conditioner uses to remove the heat and
humidity from the air in your home or business.
If your system develops leaks in the refrigerant
lines, you can end up with not enough refrigerant
to effectively cool the air. Unfortunately,
fixing this air conditioner problem correctly is
not just a matter of replacing the refrigerant.
An HVAC technician needs to find the leaks and
repair the holes in the lines, which can
sometimes be a time-consuming and expensive
process, especially when there are multiple leaks.

2. FROZEN EVAPORATOR COILS
Your air conditioners evaporator coil is filled
with refrigerant, and is responsible for
absorbing the heat from the air like a sponge. It
may sound counter-intuitive, but those coils
need warm air circulating around them to work
properly. When something goes wrong with the
airflow and the evaporator coil gets too cold, a
layer of ice can build up on the outside. When
that happens, youll get warm air or none at all
coming from your air conditioning supply
registers.

3. FILTHYCONDENSER COILS
Your units condenser coils, part of the outdoor
unit, gets rid of the heat removed from the air
by expelling it outside the building. The
condenser coil wont work well when it
gets covered with a layer of dirt and grime. This
is a very common problem in India with all the
soot and pollution in the air. When it happens,
heat transfer is impeded, and your unit has to
work harder to do its job, leading increased wear
on the parts and even system failure.

4. FAN PROBLEMS
There is a fan that blows indoor air over your
units evaporator coil to cool the air, and
another that blows air over the outdoor units
condenser to expel the absorbed heat outside
the building. If either of those fans isnt
working properly due to a faulty motor, lack of
lubrication, worn belts or too much dirt and
debris you end up with poor airflow and air
conditioner problems. If you neglect the
problem, it can lead to compressor failure,
which is often a death sentence for your air
conditioner.

5. SPILLING DUCTS
The ductwork that runs through your walls and
ceilings carries the cooled air from the air
conditioner throughout your space. However, if
there are holes or breaks in the ducts (which
can be caused by rodents or careless workers),
that expensive cooled air winds up inside your
walls where its not doing anybody any good.
And, of course, this scenario causes your air
conditioner to work harder and drive up your
energy bills.

6. THERMOSTAT PROBLEMS
Especially if you still have the old dial-type
thermostats, they could be incorrectly
calibrated, which means your air conditioner
isnt getting the right instructions from the
control system. This problem is fairly easy to
fix by replacing or recalibrating your
thermostats. If you have new programmable
thermostats, sometimes these are tricky to
program and they may be set incorrectly. If you
still have the manual, check the instructions to
make sure your thermostats settings are correct.
