I purchased this AC in almost 24k during some offer period. I am very satisfied with the cooling & power consumption. I can not guarantee but tube material seems copper, however I never found tube material mentioned anywhere whether in LG website or any other website. Noise level is as much as in other window ACs.
A great product at such low price. Cheapest price of all 1.5 ton ACs. Cooling is decent from the product and is very energy efficient. You can keep it running and dnt have to worry abt electricity bills. It has an energy saving mode when u set it to 24-25 degrees. It automatically shuts down when the room is cooled and then resumes when the room temperature rises a bit. Noise level from the AC is there, but it wont disturb you at all. Its a product for those who want good cooling at lowest electricity bills. Service - LG service is fast and responsive.Kudos
In AC name why it is written as 5 star AC as in details flipkart is showing its feature as 3 star rating. Less competency in writing or technical knowledge. ....
Go Ahead without any Hesitation.
