I would suggest -
If money is not a constraint - Go with Ogeneral/Mitsubishi
Want smart features - Go with Panasonic/LG/Samsung
Want more cooling capacity - actual cooling capacity in terms of W - Go with Daikin - 5 star 1.5 ton gives - 5280W cooling(100%)
Best services - LG/Samsung/Panasonic(much improved compared to last year)
5 star/3 star - If only 4 months use, only at nights - eyes closed take 3 star. If 6-8 months or more use and also daytime usage - go for 5 star.
3 star 1.5 ton will cost 30-40k, 5 star 1.5 ton will cost 45-55k.
1 ton/1.5 ton - Depends on sq foot of room - till 120 sqft - 1 ton is sufficient, above that take 1.5 ton, if room size> 170-180 sq ft take 2 ton
Take only inverter ACs if you want it at home - as they are new technology ones.
Warranty - check compressor warranty - 5/10 years, check PCB warranty - 1-5 years. PCB replacement cost is high - so PCB warranty should be there.
Checkout some videos in youtube regarding AC reviews.
As per my personal experience, considering all factors I bought this recently from Reliance Digital(good offer for my exchange)- Panasonic 1.5 ton 5 star smart AC 2023 model with 5100W cooling - has smart wifi features with MirAIe app. Has 5 yr PCB warranty and 10 yr compressor warranty. Its sleep profile functionality is really good. It cost me around 48k. Gave 3k for my 12-15 year old 1 ton AC additional. I bought in March end during offers.
Note : Installation will be 1-2k extra. If stand for outdoor unit required - will cost more. Also buy extended warranty - 1/2/3/5 years. Also get a AC stabilizer if stabilization issues in your area.
