Give your AC related wisdom Indore peeps

I'm planning to buy 2AC's. I'm researching online on different forums and reddit. Guys help me with following. 1. I've seen mostly positive reviews about LG ac. They have their own service network whereas other's give it out to third party, so with AC servicing is most important so I'm kinda convinced about LG. 2. My usage willbe 2-3 months in summer only so I was thinking what If I just get a croma branded AC. They're cheap and good. But I've heard mixed reviews about them. Anyone having first hand experience with them, can you share it. 3. I also saw carrier AC are best but I'm doubtful about service network and service quality. 4. Where to buy from? I'm thinking going to croma and reliance digital etc. and bargaining with whoever gives the best price. Same way I got the TV 4 months ago for 64k while their listing price for 78k. Please share your opinion about brands, service as well as any tricks I can use to get them for cheap.
