iPlease don't fall under the trap of econotech, as i have also changed my father's work place air conditioners. I took my Ac repairing guy with me to sort the matter for me, he inspected the acs, there were two types Normal and Eco mode, he recommended Normal one as he had a solid logic i.e. The econo mode has small compressor as compared to normal one. like one ton ac in eco mode is not one ton, it is almost equal to 0.75-0.85 ton.
