I am using this AC for one year yet I am not faced any problem. It is working properly since its installation in my room. its cooling power is too good within a short time it cooled properly my room. But it is good only for small room not for Hall.
I mostly like service of this company because once it making vibration and noise loudly then I called for service man and problem was solved shortly. it is save electricity and cooling fast. I can say that its value is good for it.
