For Daikin after sales support depends on where one buys from, I've 4 Daikin ACs in Ahmedabad, units bought from Future Solutions (big dealer distributor) have very good support and prompt service, while units bought from Flipkart they've assigned namesake service provider (even damaged 1 indoor unit due to faulty wiring during installations, it took couple of days more to get replacement from Daikin)
Objectively these Daikin ACs are insanely quiet and cools quickly, previously had IFB, Panasonic, Videocon ACs which I replaced.
