I just bought my Voltas Window AC which is actually working fantastic in my room it has a power cut power off on when it is reaching at desired temperature Energy Efficiency is 2.93 and it is 3 star electricity saving Tata product I really enjoyed with my family but sometimes it make a noise which can be repaired through its toll free number . It’s cooling effect what we all observed is far better than split AC and it is also easy to maintain from service point of view and economical too
