It is like a family member. This cooler was bought long time ago, do not even remember how much we paid for it:). It has been a life-saver during the summer months. No service/maintainence required as such. Although, it needs lots of water to be filled but that water is retained for a long time, at least for 10-15 hours if filled to it’s capacity. The cool/swing mode is the one it is set up at with the fan speed being set up at Gentle mode. The noise generated by the fan is something to be worked upon.
