If your air conditioner continues cycling on and off, it is most probable that your AC system is short cycling. Because of filthy, damaged, or deteriorating parts, or for a variety of other mechanical or electrical causes, an air conditioner may cycle on and off frequently. This might imply that your system goes on and off every 5 to 10 minutes, depending on the indoor and outdoor conditions.


Have you always struggled with this issue? Or did it start lately, when you installed a new air conditioning system?

An oversized air conditioner can swiftly chill your home but will not reduce humidity and will run for a short period of time. Because the unit cools the house swiftly, it turns on and off quickly (short cycle). A system that is too big will not have an adequate refrigerant cycle and may have a variety of issues, such as turning off shortly after turning on.

Parts will begin to break down. Also, an oversized unit does not do a good job of humidity removal; extra moisture in the air will cause pockets of heat in the home since moisture absorbs heat. Your air conditioner may be too big.

If your air conditioner cycles on and off every 10 minutes, an oversized air conditioner might be to blame.


It's a popular myth that refrigerant gets depleted throughout the cooling operation of an air conditioner. Low refrigerant levels, on the other hand, are produced by tiny openings that enable the refrigerant to escape.

Your air conditioner may be running out of refrigerant if you have a refrigerant leak in your AC system. The refrigerant is a coolant that travels through your air conditioning system, absorbing heat and cooling the air in your home.

Leaks of refrigerant can be very hazardous to you and your loved ones. If you suspect a leak, contact an AC expert right once. Refrigerants can be dangerous to people and should only be handled by a trained specialist.


If your AC compressor is overheated, malfunctioning, or starting to fail, it will cause your AC system to shut down repeatedly and restart quickly, just like when there is a refrigerant leak.

If your AC compressor shuts off after around 2-3 minutes of operation, it is most likely overheated or starting to fail.

Condenser coils are more exposed to the weather than any other component of your air conditioning system since they are positioned outside of the property. If they are not maintained on a regular basi, they might get caked with dirt and dust. If a condenser accumulates a heavy layer of dust, it may struggle to complete heat exchanges. This accumulation of heat drawn from within the home can cause overheating, forcing your air conditioner to shut down and perhaps leading to a catastrophic malfunction.


Is your air conditioner going on and off abruptly, after only a few seconds or minutes of operation? If your air conditioner starts on and then instantly switches off, you most likely have an issue with the electrical components or the run capacitor.


The run capacitor in your AC system delivers the initial spike of energy required to turn on your AC system as well as continuous power to keep your system operating. When this part fails, it might cause inconsistent power to be delivered to your air conditioner, causing it to cut off abruptly and then back on.

If your air conditioner begins and then stops after a few seconds, or if it switches off after 30 seconds, there's an issue with your run capacitor, and you'll need to replace it.


Unfortunately, there are a few areas where electrical problems might cause your air conditioner to cycle on and off frequently. Testing electrical connections may be difficult and dangerous for the inexperienced individual unless you have the necessary skills and equipment.

The thermostat, electrical connections, circuit boards, and run capacitor may all be causing electrical troubles in your system. The thermostat is the air conditioner's brain; a faulty thermostat might cause your system to cycle on and off fast. Electrical connections transmit signals between the thermostat, circuit boards, and relays; faulty electrical connections can cause signal loss, leading your device to shut down prematurely and cycle briefly.

Circuit boards may also have failed or have faulty connections. Start capacitors assist the unit in beginning, and a faulty run capacitor prevents the unit from continuing, therefore the unit may be starting up but will not continue to operate if there is a defective run capacitor. The thermostat, electrical connections, circuit boards, and run capacitors can all cause short cycling.


Ultimately, there could be many reasons why your air conditioning keeps turning on and off. It’s an indicator for you to be alert that there might be a fault in the system.

It could be from an oversize air conditioner, refrigerant leak or electrical issue. As it could be a highly hazardous fault, it is best to leave it to a trained professional.
