We went to a shomroom of croma and then tend to buy a new air conditioning machine . So the croma sales person show cased us hitachi window ac 1.5 tons . Which look cool and then we checked the reviews and then we purchased . It is now 4 year that it is working and giving us amazing cool air . We are at the top floor instead of that it is providing amazing cool wind in the room . I would highly recommend this type of air conditioning machine . It is the most strong air conditioning machine and aborbs sun rays and does not trip easily. If you make the air conditioning Machine temperature on 16 degree then you will feel you are in a shimla place instead of living in delhi
