Air Conditioners Normal Noises
There are many normal noises associated with room air conditioners. Below are the more common noises:
- Air Flow Noise: An air conditioner must circulate indoor air to heat/cool the occupied space. Therefore, air noise will be heard when the fan is operating.
- Thermostat Click: When the compressor cycles on and off a metallic sound may be heard. This is considered normal.
- Water Dripping Outside: Air conditioners must be installed level or slightly tilted to the outside. Consult the Installation Instructions for your model. On exceptionally hot and humid days the air conditioner may permit excess water to drip on the outdoor side of the unit. This is considered normal operation.
- Fan Runs Continuously: When the energy selector is in the cool or fan position, the fan will run continuously. This is normal operation.
- Front grille loose: Room cabinet or moveable air directional louvers are loose or broken. They can be fixed by adjusting them and snapping them back into place as normal.
- Improper installation: This may cause a vibration in window sill. Check that the side panels are properly fastened to the window frame and window sill with screws.
- Beeping: When power is connected. See Air Conditioners Beeping
