after a market survey i decided to buy an ELECTROLUX ac, but now i regret my decision

this review is for ELECTROLUX oxygen ac 1.5tn only which i purchased about 2 months back
following are the pros and cons:
PROS:
1)attractive grill, good l.c.d remote control,good looks and controls
2)ioniser(oxygen) function,sleep,auto,dry etc modes
CONS:
1) fan motor noisy ,permanent lubricated but brand appears to be local: lakwin?
2)cooling is poor, temp never goes below 23c even after 3 hrs of compressor running continuously+ outside temp of 37c, room size 125sq ft,month of april and normal room temp of 31c. although the min temp given on lcd panel is (16c).
3)compressor make is hitachi(shanghai) i.e made in china
4)power consumption is 2.1 unit per hr as compared to co claim of 1.8 u
i have no idea about other brands like voltas,lg but certainly dont go in 4 electrolux
