Hello guys. Tody I am giving tips on coolers.As we know that summer season started and every normal person going to buy a cooler for these summer. But before buying any type of cooler you have to took care of some important things.1. First you have to take care of cooler fan. It not should be a fan but it hane to be a compressor because a fan blow air in room but compressor compresses the air in room which is very effective then any fan.2. The motor of the cooler should be with copper winding. Sometimes we buy aluminium winding motor cooler but these cooer works for only one season and next season we have to replace it. And the copper winded motor work for 3-4 seasons.3.For a best cooling by cooler in the room we have to use a better quality of water pump. A pump which can punp water for 2-3 floors is best for any type of cooler for condescending.By use of these specifications you will definately got a best cooler for a very long time .And last thung the body of cooler should be in Metal.Thank you.
