It’s been 1 year since I had this AC in my 15x15 ft. room. the AC works really well with no problems till yet. Even if its a hot day like 42-43 degrees outside, the AC cools the room efficiently and the powerchill option makes the cooling faster. The AC cools the room in less than 3-4 mins on rainy days and takes upto 12 mins on a hot day. Just make sure to give it a proper service and it won’t let you down. Plus it’s quiet.
