After sale service is very bad.they fix the stabiliser of their choice and when there is a problem with it,they ask you to go to Tnagar service Center of the stabiliser brand.they will neither handle the problem nor help you in any way.you can imagine the difficulty for a person living in OMR to go all the way to Tnagar and live without the ac in this sweltering heat...they talk well during installation.especially mr Radhakrishnan an chips service team but when it comes to service it is pathetic
