I have purchase this ac before 2 years. and this seems to be that it is not working properly now . the company offered the only two times service . but after the service of 3 months its works abnormal like the sound comes too much which make the disturbance in the sleep it takes long time to cool . and I am not satisfied with this product .sometimes it lead to the leakage of water from the ac. it’s just waste of money I preferred you to not to take this ac.as well as the service is also not good if its paid service you will highly charged for different products replacement .so I think you should not waste your time as well as money in it.
