I am a proud owner of a samsung 1.5 ton split AC installed at my room. I would like to say thanks to the company and the engineers who are behind to make this such an amazing product. actually for what maximum I am convinced is only related to its very less electricity consumption as it gives me a very low electricity bill to pay. my ac is a 2 star product and still I cant believe how can it consumes this low electricity. I love my ac. thanks samsung
