Invertor ac use dc components to give u saving in bill. the more the dc components the more the bill reduction .. in all 7 components can be run on dc .. most ac in pakistan r one or two dc components like orient, changruba .. then the more latest models of kenwood and gree are 3 dc units .. if u go higher in price like daikin, acson etc these r 4 or 5 dc components ..
practically i have found kenwood 75% saving ac to be working at par with gree .. gree is expansive by around 10k due to brand name .. i havea korean ac with 4 dc components which runs better than kenwood but they dont have local repair support so wont recommend that
- recommended kenwood 1217 .. 1817 .. or similar model in 75% saving
newer models with wifi support and 4 dc components r likely to be launched by kenwood and gree with price above 70 and 80 k would be even better
