under 40k you will probably get 1 ton
I went to buy another a.c in market a week ago (Low voltage startability series or LVS) and a shopkeeper who is friend of my uncle told me not to buy it. its just a standard A.C with big capacitor no stabilizer or something, so I bought a stabilizer instead for my pel unit.
Gree is working fine have good sale these days. many shops are full with gree.
If you want to save electricity get inverter series (not dawlance if you plan to run it on solar panel lateR)
dawlance monogram series is also get and less no of complaints , Dont go for orient
