Why is my Fujitsu Inverter Halcyon making noise?
The noise from your Fujitsu Air Conditioner can be attributed to a few things: * You might hear water flowing in the air conditioner's pipes during or after operation. * The sound of refrigerant flowing may be noticeable for 2-3 minutes after starting. * During heating, a sizzling sound may occur due to automatic defrosting.
