What Is Short-Cycling? Your air conditioner uses refrigerant to absorb latent heat found in indoor air and transport that heat outdoors.Short-cycling happens when the cooling cycle becomes much shorter than the usual 10 minutes, causing the compressor to turn on and off more often than usual.
Is it normal for AC to kick on every 10 minutes?
Your compressor must be on for the cooling cycle to complete.During a cycle, your compressor runs for 10 minutes and stops for another 10. This cycle is normally repeated another two times in the course of an hour. When your cycle does not last for 10 minutes, your compressor will keep turning on and off.
How often should AC kick on?

Why does my AC unit keep cycling on and off?
Your air conditioner may be short cycling because it is repeatedly starting up then overheating (and shutting down) due to a bad compressor, dirty filters, dirty coils, low refrigerant, or frozen coils.A malfunctioning compressor will overheat.
