All inverter ACs are pretty much the same - Gree, TCL, Panasonic, Samsung, Mitsubishi, Kenwood, Haier, Dawlance, Orient.
Most of them use the same parts covered under their own branded boxes.
I prefer original brands, not resellers of unknown Chinese parts like Orient, Dawlance, Pel, Kenwood.
Original brands with decent reputation are: TCL, HiSense, Gree... Haier has original name but its products appear to have more negative reviews than others (all have negative reviews).
From non-original brands, Kenwood seems to be doing quite good.
If you have decided on Dawlance or Haier, then go for Dawlance, as at least their warranty on paper is huge.
If not strict on Dawlance, I'd suggest TCL or Kenwood. Go for any among these 3: Dawlance, TCL, Kenwood. They provide best value to price ratio. HiSense is also great but not sure about their after sales service centers.
Avoid Gree. Same quality as others but overpriced. Avoid any 1.5 ton AC over 79-80k Rupees. Will not provide any better reliability or innovation.
