Recently bought this ac. Its cools effectively within no time. It has a capacity of 1 ton. It makes 28 db noise only. The power input is 1150 w. It provides 4 way air flow with auto air swing having an air circulation of 425 CMF. The most importantly it can be run on inverter which is great. It has various modes to suit better such as turbo mode, cool mode and sleep mode with timer and auto restart facility. It has a rotary compressor with R-410a refrigerant which is quite effective. Very good service provided right from the day of installation. Nice product
