If you excuse me, the ambient temperature of 28 degrees is outside and the other is from the interior, it is a room for storing medications and can not exceed 25 degrees but this problem has a long time since I do preventive maintenance and in winter it also cuts Fast, I distrust the compressor to increase its temperature since it is an air that works permanently throughout the summer and is already many years old, it may already have its wear, the rare thing that does not cut due to amperage, thank you very much.-
