Daikin airconditioner is really silent, literally you need to touch the unit to find out it is running. As they say cooling without a fuss. You need to add minimum 4K for installation as Daikin dont provide any installtion cables/pipes as other makes do in Indian market. Installation technician from daikin was very young and lacked experience, but then it doesnt require rocket science to install an AC. It is advisable to inspect everything yourself what the technician has to say rather than leaving things to the inexperience ( I faced problems in centering the indoor unit into the wall) . Overall happy with Daikin but can do better with expericend technicians.
