What is the 3-minute rule for AC?

The 3-minute rule for AC is a guideline to prevent short-cycling. It means your AC should run for at least three minutes before shutting off. If it's cycling on and off rapidly, it could indicate an issue with the thermostat or the unit itself. This can lead to inefficiency and damage. A pro can check for these problems.
