Air conditioning systems turn on and off to maintain the desired temperature. Cycling is a normal function of the cooling equipment and is nothing to be worried about. However, in case the air conditioner cycles frequently, it should raise a red flag. It’s called AC short cycling.
In this article, we will explain some of the common reasons why air conditioners short cycle and what needs to be done to address a AC short cycling problem.
1. Air conditioner refrigerant leak
Short cycling can occur due to a refrigerant leak. Contact a professional technician from Southern Air for the air conditioner repairs. A technician will use specialized equipment to detect and resolve the leakage problem.
2. A faulty expansion valve
In case the thermostat becomes faulty and does not release the refrigerant into the coil, this will result in abnormally high pressure inside the unit, due to which the compressor will turn off. The high pressure trips the safety control of the air conditioner due to which it will cycle on and off on a frequent interval.
3. An overheated safety switch
The compressor motor will also turn off quickly after starting due to overheating of the safety cut-out switch. It will restart when the switch has been turned off, but will close quickly due to overheating. Call Southern Air for assistance if you suspect this is a problem for your air conditioning unit.
4. Icing on the air conditioner coils
A dirty filter or improper refrigerant sometimes results in the formation of ice on either the cooling or evaporator coil. The air conditioner will turn on when the ice melts and then quickly turns off due to ice formation.
5. A fault in the thermostat
A fault in the thermostat also results in AC short cycling problems. Also, loose thermostat wiring, clogging of dust on the bimetallic strip of the device, or the wrong placement of the device can contribute to short cycling problem.
6. A large air conditioner that’s too large for your home
An air conditioner that is too large for the home can result in frequent short cycling problem. The cooling device will turn on and then turn off quickly after cooling the room. This will not only result in uneven cooling, but also damage the unit due to short cycling.
The problem can be mitigated by opening the doors inside the house, or running the blower fan at a lower speed. However, the permanent solution to the problem is to buy the right sized air conditioner.
