A good product in Air Conditioners by Mitsubishi. Nice product at all. Cooling process is good. No any kind of sound till date in 4 years. Good quality and design. Nice product specially for office. Looks nice and quality of exterior are also good. Support and services are superb as related to other company which did'nt care much about customers like Samsung. Whenever I call for maintenance, they always respond within 24 hours and its feels good. The compressor inside is very relaible. No sound, good cooling quality, easy maintenance. All good.
