Never seen. Never heard. Ever aesthetic.
Apart from being reliable and trouble-free, the unique low noise feature in the Blue Star Concealed Split AC makes it the quietest in its category. Its low height of just 266 mm (11 inches) makes it easy to conceal, giving you the great look of central air conditioning along with higher head-room under a false ceiling.
