Introduction
A window air conditioner can provide the
much-needed relief you need when the temperature
rises, especially in homes without central air.
To ensure you stay cool all summer long its
important to know how to troubleshoot some common
problems with the unit. You may not be able to
fix every problem, but at the very least have an
understanding of what the problem could be. From
that point you can decide whether you need to
repair the unit or purchase a new one.

My Air Conditioner Wont Turn On
First thing to do if youre A/C unit wont turn
on is to check for power. Is the air conditioner
plugged in? If so, test the outlet by plugging
another appliance in to that same outlet. If the
outlet is receiving no power, check your circuit
breaker. If the A/C is receiving power but still
doesnt turn on, there are a number of issues
that could be wrong and would require repair
including the wiring, thermostat, compressor,
selector switch or control board.

My Air Conditioner isnt Cold Enough
This is a common complaint and why its important
to purchase the right BTU size air conditioner
for the space you are trying to cool. Check your
BTU size here to see if you purchased the right
size for your space. You may need a new air
conditioner with a larger BTU size to get the job
done. If you have the right size BTU use a
thermometer to get the temperature of the room
and compare that to the temperature you want it
to be.

If there is a 15 degree difference you may be
asking the unit to do more than it is capable of.
Try resetting the temperature to 10 degrees lower
than the room temperature. If the difference
with the thermometer is less than 15 degrees,
check the air damper. If it is open it will bring
in outside air and this is bad for the units
efficiency. Check your back cover also, many
people forget to remove this cover after the
winter season.

Lastly check the condensing coils, which are
located on the warm end of the A/C unit. Remove
the air conditioner cover to access the coils and
clean them with a soft brush.

My Air Conditioner isnt Blowing any Cold Air
If youre not feeling any cold air coming from
the unit but the fan is blowing, make sure the
thermostat is set appropriately first.  Next
check the compressor motor, which is a small case
inside the air conditioner. If it is humming
continuously, it could be the condenser,
evaporator or compressor, all of which would need
service from a professional.

My Air Conditioner is Leaking Water
If you find your A/C unit is leaking water this
could be a sign that it wasnt installed
properly. Re-check the manuals installation
instructions to be sure the installation was done
correctly. Most likely you may just need to tilt
the unit back slightly to allow water to run off.

My Air Conditioner Stinks!
If you have consistent problems with your A/C
unit and you have gone through all the
troubleshooting steps, the unit may need service
from a professional or you it may just be time
for an upgrade.  An average window air
conditioner has a life span of 8 years, and this
varies on how often it is used and how well you
maintain the unit. Feel free to visit
