if you buy non-accidental , then its awesome . for 1-2 people i run it on 26-24 with medium fan with air directed partially towards passengers.
With full 4 passenger , i ran it on 20-22 with 2 directed back seat and 2 on front .. no complains . but ofcourse dont expect it to cool the whole cabin like a 1300cc+ if you set too low and full fan after 15-20 mins its the same , but then the car power affected when climbing like bridges
but i would say its way better than any 800-1000cc pkdm here
