buddy i got my 1000km free first inspection today & ac was checked too. they had a thermometer with fan (blades) kind of thing in the thermometer and they checked the cool air temp coming out from vents and it was all confirmed OK.
so i would say do not panic, you will get everything checked at 1000km inspection and if you still worried then goto suzuki immediately and raise your concern.
there might be a possibility of not enough gas in the cooling system.
