I need ac who consumes low electricity

hi! i am from lahore. i need the ac which consumes low electricity and the price of ac is not a problem. which air conditioner i should buy and from where?

Price no object.. Acson Inverter

Price little object.... Gree H series ..

But a DC inverter AC

You will only feel the difference in consumption if you run it continuously for like all day and don't turn it on and go out and come back n turn it on again. The consumption is not any different nor does it justify the increased initial cost.
