Solution

High Pitched Chatter

Today's high efficiency compressors may have a high pitched chatter during the cooling cycle.

Sound of Rushing Air

At the front of the unit, you may hear the sound of rushing air being moved by the fan.

Gurgle / Hiss

"Gurgling or hissing" noise may be heard due to refrigerant passing through evaporator during normal operation.

Vibration

Unit may vibrate and make noise because of poor wall or window construction or incorrect installation.

Pinging or Swishing

Droplets of water hitting condenser during normal operation may cause "pinging or swishing" sounds.

NOTE: Don't try to drill any holes on the base pan to eliminate the normal sounds, otherwise it will void the warranty.
