If you want to buy TCL elite then buy 1.5 ton. It's indoor is big and air throw is also good. Will cool down room faster. TCL elite 1 ton has small indoor and air throw is also not so good.
If you want to buy Haier then again i will recommend to buy 1.5 ton Candy since due to bigger indoor and faster throw room will cool down quickly. Don't worry amperes will come down to the level of 1 ton air conditioner.
There is 1 issue with candy series is that its vertical grills are manually adjustable only.
But its just my opinion. You may go for 1 ton as well depending on your budget.
