Normal operating sounds …

When your room air conditioner is operating normally, you will hear sounds such as:

•Droplets of water hitting the condenser, causing a “pinging” or “clicking” sound. Water droplets help to cool the condenser.

•Air movement from the fan, especially on high fan speed settings.

•Clicks from the cooling cycle.

Sounds also may be caused by house construc- tion – such as vibration of the unit due to wall construction or unsteady window mounting area.
