Why Your Air Conditioner Might be Short Cycling

One of the biggest problems to afflict air conditioners is short cycling. This is when your air conditioner keeps turning itself on and off every few minutes. While this may seem more annoying than dangerous, it can actually cause catastrophic damage to the system if allowed to continue for a length of time.

The reason that this is so damaging is because it locks the system into the startup part of its cycle, which is the most stressful part of the air conditioner’s operation. The system is not designed to handle this amount of constant stress, and being subjected to it for a prolonged period of time shortens its lifespan. Let’s take a look at what can cause short cycling, and what you can do about it.

Thermostat Malfunctions

The thermostat is the brain of the air conditioner, responsible for actually turning it on and off when needed. A malfunction in the thermostat, usually a short in the wiring, can lead to incorrect signals being sent to the air conditioner. This is one of the most common causes of short cycling. If you suspect that your thermostat is acting up, give us a call and we’ll inspect it.

Damaged Compressor

The compressor is the part of the air conditioner responsible for circulating refrigerant gas through the system during operation. The part is only designed to handle gas, though. If it is exposed to liquid, as sometimes happens if there is a problem with the refrigerant, the compressor can become damaged. This throws off the rhythm of the entire air conditioner, causing it to short cycle. Typically, a damaged compressor will need to be replaced in order to restore the air conditioner to proper function.
