How do I tell if my AC is short cycling?

You can determine if your air conditioning system is short cycling by observing its operational runtime patterns and noting how frequently the outdoor unit and indoor blower turn on and off. If your system fires up, runs for only three to seven minutes, shuts down for a brief period, and then repeats this cycle continuously throughout the day without ever reaching a stable idle state, it is short cycling. Other distinct physical signs include rooms that feel humid, sticky, or unevenly cooled, despite the air conditioner seemingly running constantly in brief bursts. You may also notice your monthly electric bill increasing dramatically due to the high energy draw of frequent motor startups, accompanied by the persistent clicking sound of the electrical contactor engaging and disengaging every few minutes.
