Why does my AC turn on every 10 minutes?
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. This excessive stopping and starting adds wear on the compressor while robbing your home of its cooling comfort.

. Also, running with fewer cycles (turning on and off) is not necessarily a bad thing. In fact, running longer can be positive because it: Helps dehumidify your home (a big plus in Florida)
Is short cycling AC bad?

Can thermostat cause short cycling?
Your thermostat could also cause the HVAC system to cycle on and off rapidly
, a process known as short cycling. Your furnace or central air conditioner spends a good amount of energy simply turning on and off, which is why you want yours to run for at least 15 minutes at a time before shutting off.
Why does my AC cycle on and off so much?
A dirty air filter
means your air conditioner will have limited airflow. Hot air builds up inside the system, while cool air can’t get in. This causes the system to overheat, which in turn causes it to cycle off. You need to regularly clean or change your air filter in order to prevent this from happening.
