LG window ac 1.5 ton is a powerful machine and I am fully satisifed with the performance. I have been using the for the last one year and no complaint and problem so far. As far as cooling is concerned this product is a value for money and cools very fast. However only problem is that it is not eco-friendly and cost you some addition in your electricity bill. I suggest ACs having 5 star ratings which cost u less.
