Before calling for service:
Performance problems often result from little things you can fix yourself without tools
of any kind.

with the proper voltage.

or trips circuit breaker

l Clean the filter.
l Clean the coils.
l Use exhaust/venting fans to reduce room heat.

Normal operating sounds
When your air conditioner is operating
normally, you will hear such sounds as:
l Droplets of water hitting the condenser,
causing a “pinging” or “clicking” sound.
Water droplets help cool the condenser.
l Air movement from the fan - especially on
High fan speed settings.
l Clicks from the cooling cycle.
Sounds also may be caused by house
construction - such as vibration of the unit
due to wall construction or unsteady window
mounting area.
