Why Does My Air Conditioner Keep Turning On and Off?

If your air conditioner is constantly turning on and then back off again, it is a problem that shouldn't be ignored. This issue is known as short cycling, and it not only means something is wrong with your air conditioning system, but it also means your home is not being properly cooled. You need to determine what is causing this short cycling and have it fixed. A trained technician at J.R. Perkins Heating & Cooling can help diagnose the issue for you. If left alone, short cycling will cause damage to your entire air conditioning unit. 

Thermostat Issues

The most unsuspected cause of short cycling could very well be your thermostat. A thermostat gauges the air around it, and as such, it decides when it needs to activate your air conditioning based on that ambient temperature around it. This means that something like sun shining on your thermostat, for example, could cause your thermostat to misread the home's temperature. However, when it senses cool enough air, it will turn your air conditioning off. Having a thermostat in the sun or over a vent can cause short cycling issues.

Low Refrigerant

When the refrigerant is low in your air conditioner, the compressor levels become unstable and it can cause short cycling. Refrigerant is necessary for absorbing heat and producing cool air from your air conditioner. However, refrigerant doesn't just run low. When you have low refrigerant, it means there is a leak that needs to be rectified before your air conditioner stops working altogether.

Air Conditioner is Too Large

When it comes to air conditioners, bigger is not better. Any air conditioning technician at J.R. Perkins Heating & Cooling will agree. What happens when an air conditioner is too big for your home is that it cools the house too fast and causes the air conditioner to short cycle. This seems like it would be preferred, but air conditioners take increased wear while short cycling, and also suffer from diminished energy efficiency.
