Why does my AC compressor keep turning on and off?
Why does my AC compressor keep turning on and off?
Your air conditioner may be short cycling because it is repeatedly starting up then overheating (and shutting down) due to a bad compressor, dirty filters, dirty coils, low refrigerant, or frozen coils. An overcharged system will cause liquid Freon to get into your compressor and cause it to malfunction.
Why is my home AC short cycling?
Frozen evaporator coils are a common cause of short cycling. Sometimes, air conditioners freeze up when they’re running while it’s too cold outside, usually at night. In other cases, freezing may be caused by a dirty filter or a mechanical problem. Shut your system down, allow it to thaw completely, then run it again.
Why is my air compressor short cycling?
Pressure or temperature control differential is too small: When the pressure controller’s low pressure differential is set too tight, it can cause the compressor to short cycle. When your temperature and pressure differential is too small you’ll take longer to achieve set point and use more energy use in the process.
How often should home air conditioner cycle on and off?
Ideally, a properly operating air conditioner should cycle for roughly 15 to 20 minutes, two to three times per hour. If the temperature inside your home is very high, is much higher than the temperature that your thermostat is set at, or the outside temperature is very high, the run time will increase.

If the AC compressor cycles on more than 4 times in an hour, it could be due to short cycling or another internal problem.
Why does my AC cycle on and off every 10 seconds?
An air conditioner or heat pump that is cycling off and immediately back on or cycling off/on every 10 seconds is abnormal and is likely to damage the equipment. I would turn the system OFF while waiting for repair, as I worry that more components will be damaged.
How long does it take for an air conditioner to cycle?
The HVAC system then circulates cool or warm air throughout the home or building, until the desired temperature is reached. Once the temperature is reached, the air conditioner kicks off. This is one cycle and usually takes around 15 minutes.
What causes an air conditioner compressor to stop working?
If someone manually turns the air conditioner thermostat up and down or on and off too frequently, a hard-starting compressor may find that it has been shut down with high internal head pressure inside the compressor.
