I purchased symphony jumbo air cooler in 2011 but I had not used for one year initially it worked good but after some days water pump in the cooler has defect and its pumping pipes for the four sides of the grass is short so we can’t able to adjust it. I replaced the water pump with another company it is working very good. I am using symphony air cooler for occasionally but after 3 years motor winding in the cooler has been damaged. Though it is a standard company there serving does not respond so I replaced motor winding with another company it is working good
