It is an 5 star inverter ac with latest technology .
I have been using it scince 2 months now and it has no problem.It is very quite and makes very less noise.It consumes very less electricity.
I use it aroumd 12 hours a day and the ac bill is only around 2100 per month which is very less for a 1.5 ton ac.I just love the ac and planning to buy 1 more for the other room.
