First week of February I bought ogeneral 1.5ton ac bearing model number asga16 series. it was fantastic performance on cooling the room, even though room is bit big at 22 degrees operation of ac cools in 10minutes . there are many options incooling methods provided by ogeneral . there also a power option which colls the room quickly . but only one disadvantage is copper wire will not e provided which is 850 per meter .
