    The EER will be same. Its Cooling Capacity in Watts / Power consumption in Watts.
    In your case, for both the options its 5046/1838 = 2.74

    Now, the reason the star rating has changed is the because the AC which you bought (2star) is probably a newer model. The govt decides the star rating. 2.74 was 3 star in 2012, but in 2013 its only 2 star. In the next year, your AC is only 1star rated.. and it goes on. This calls for the AC manufactures to make the unit more and more energy efficient in the coming years.

    I had started a thread a long time before, have a look at this, you will have more idea.
