I will disagree with you.
Anything over 3 EER is good for a foreign brand of the likes of LG Mitsubishi Sharp Daikin Acson samsung.
When coming to pakistani/chinese companies they are all in competition with EER value. While EER value of gree haier kenwood may not be true, it is still better to buy highest EER value because if haier says 3.5 it must be atleast 3 on international level of truth. If haier says 3 then it must be 2.5.
So even if they are fooling people it is safer to go with 3.5 or above in local brands as that may closely mimick the international standards.
All acs with eer of 3.5 whether pakistani or foreign do stabilize in amps to 2-3 amps. Amps is what calculates consumption and i have seen gree haier kenwood all achieve lower amps with whatever eer they state.
Higher eer will also show you that particular ac is latest when you compare eer of same local brands.
Pakistani company may apko hitachi quality ka truth aur ac nai milna.
