How can Hitachi Ace 1.5T non-Inverter model have EER>11.0 ?

[hotshot05]

I am looking to buy a new AC. Was looking in Snapdeal when I came across this model - http://www.snapdeal.com/product/hitachi-rau518etd-split-15-ton/768347681?pos=78;142

Did not find this model on the Hitachi website. But found something almost similar - http://www.hitachi-hli.com/e-shop/product-details/hitachi-ace-follow-me-1-5-rau518euda-tr/10
They posted the specifications here - http://www.hitachi-hli.com/images/products/specifications/spe_1390908227.pdf
The 1.2T model has an EER of 12.98!!!

I have looked at the inverter models and non-inverter models of many manufacturers. Mostly the EER is around 3 or 4.
Is Hitachi doing a media gimmick or is this one really this good?

Because EER is BTU/Watt-Hour and COP is Watt/Watt. BTU = ~3.4 x Watt. The COP value is what you should be looking at, and Hitachi lists it as 3.8 in their spec sheet. Some companies mistakenly use the term EER to represent COP.

That explains it. Almost had a heart attack after seeing the specs.
