The thing is, Carrier is a very well-known brand and rightfully so. Their range of appliances provide you with incredible functionality. On the other hand, Daikin is not very well known, especially in the Indian market. However, Daikin proves much better and more functional than Carrier. It is rated higher and provides added durability and features. If you are looking for an air conditioner, both brands are acceptable, but Daikin remains better than Carrier.
