Can thermostat cause AC to short cycle?
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 air conditioner start then stop?
Your unit could be low on refrigerant. This transformation cycle helps absorb heat and lower the temperature of the air. If your air conditioner is low on refrigerant, this means there is a leak. Low refrigerant messes with the pressure control in your compressor and causes the machine to continuously reset.
How long should AC be off between cycles?

Why is my air conditioner cycling on and off?
Low Refrigerant You may know it by its brand name of Freon®. When your refrigerant is low, the needed compressor-pressure levels are affected. This triggers your compressor’s low pressure control, shutting off your compressor. When the pressure rises and triggers your AC to restart, this causes the short cycling.
