Normal Sounds
When your air conditioner is operating normally, you may hear sounds such as:
Droplets of water hitting the condenser, causing a pinging or clicking sound. The water droplets help to cool
the condenser.
Air movement from the fan.
Clicks from the thermostat cycling.
Vibrations or noise due to poor wall or window construction.
A high-pitched hum or pulsating noise caused by the modern high-efficiency compressor cycling on and off.
