AC suggestions - 5 star AC with best service

Looking to buy our first AC. Till now we never needed ac, but recently we moved to a new place. Since our flat is on top floor (6th floor), it has become horrible during few hot sunny days. Even during a few days in non-summer seasons, the heat during afternoon is high. So I'm thinking it's better to go for 5 star ac instead of 3 star, as I feel we might be using atleast for 6 months in a year. Also, 1.5 ton is what I feel is sufficient, do let me know.

  • Room size is approx 170sq feet.
  • Budget Rs.40k-50k
  • Smart/app features - not compulsory but good to have.
  • Top preference - service is my top priority apart from cooling performance. As I don't have enough knowledge using these, I don't want service men trying to fleece or cheat us.
  • Not expecting lowest cooling temps, if ac can maintain 21-24 temps without struggle, it's fine ig.

Any other suggestions for AC usage/installation are welcome.
 
LG for best service and Daikin for best cooling in that budget.
 
5 star and 3 star both would essentially work the same, the efficiency comes into play, when temps are lowered and ACs can lower their output, at peak draw. both will consume the same energy, also have you considered how your room is oriented wrt to the sun? basically is the sunlight directly streaming into your room? does the room have glass windows? if yes to both, then you would be better served investing in some curtains, otherwise no AC will be able to cool the room

1.5 ton seems to fit your usecase, and you can wait for sales and see if Mitsubishi prices come down, they have the best cooling imo
