My Sharp 18MV chills a 266sqft room with Terrace and situated in the west! But yes it goes up to 1.9Kw at ear chilling 16C temps that I set for an hour and then I set the Temps at a comfortable 25/26 C and it consumes between .5 and .7Kw in a hot afternoon!If its evening or 5 pm that power consumption stays put at .3/.4Kw. Amazing performance I would say! And that AC works great ,Kolkata is Hotter and Humid than mumbai any day.
