Normal operating sounds
When your air conditioner operates normally,
you will hear sounds such as:
l Pinging or clicking as water droplets hit
the condenser. Water droplets help cool
the condenser.
l Air movement from the fan, especially on
HI COOL setting.
l Clicks from the cooling cycle.
Sounds may also be caused by house
construction - such as vibration of the air
conditioner due to wall construction or an
unsteady window mounting area.
