How long is AC short-cycling?

At its shortest, a cooling cycle will last for 15 minutes. This is how much time the compressor and air handler need, at minimum, to distribute cooling around the house. When the compressor runs in shorter cycles, especially under 10 minutes, then it's short-cycling and needs attention.

3 Reasons Your A/C Is Short Cycling

Why does my AC turn on every 5 minutes?

Is it better for AC to run constantly?

The constant running of your AC unit will reduce pressure in the evaporator, or cooling coil until it freezes over, according to Cool Today.

An AC should run 12 to 16 hours a day on average summer days when the air conditioner is properly sized. On the very hottest days of summer, don't be surprised if your AC runs 20 hours or more, especially if the weather is well above the normal heat range.

How often should AC fan run?

You shouldn't need to run your fan continuously (or even often) if you have a newer HVAC system. These systems have a fresh-air intake that brings in some outdoor air which might need to be cooled or heated. Running your fan can make it harder for your AC or furnace to handle this extra work.

Is it normal for my AC compressor to cycle on and off?
