Your split system air conditioner uses various moving parts to cool the air in your home. Because of this, it is normal for a split system air conditioner to make a bit of noise whilst it is in use.
If the noise seems excessively loud, however, there may be a problem with the air conditioner.
The first thing to check is that the air filters in the air conditioner are properly installed and seated in their slots. Following this, check that the door that covers the filter. If this cover is not properly closed, small vibrations in the air conditioner will cause the cover to make a rattling sound.
For more information, check the User Guide for your product.
If you have attempted these steps, and the air conditioner is still making abnormal noises, please record a short video and contact our Customer Care Team.
