Why Does My AC Keep Turning On and Off So Often?


If your air conditioning unit keeps turning on and off constantly without completing a cycle, this is a bigger problem than you might think. This problem is also called short cycling, and West Chester residents face this problem quite often.

As temperatures start getting higher during the summer months, it is necessary to make sure that your air conditioning system is prepared to keep your home cool and comfortable during the searing heat. If you are already facing a short cycling problem with your AC, you should not waste any time in calling professionals for air conditioning repair in West Chester, PA.

In this post, we will tell you about some of the problems that could be causing your AC to repeatedly turn on and off so that you can understand the severity of the situation and call professionals to come and fix your AC.

Why Your AC Keeps Switching On and Off

Here are some of the common reasons your air conditioner might be short cycling.

1. Refrigerant Leak

The refrigerant in an air conditioner is responsible for absorbing the heat from inside the house and transferring it outside during the summer. If there is not enough coolant flowing through the AC, the compressor pressure can become unstable, causing it to short cycle. This can cause severe damage to your AC and you need to get it fixed immediately.

2. Airflow Problems

When was the last time you changed the air filter in your AC? If you don’t remember changing it at all, you might have a clogged air filter. A clogged air filter restricts airflow, causing the evaporator coil in your AC to become frozen, which in turn will force the unit to turn off before it cools down your home. The air conditioner turns on again once the ice melts before the coils freeze again. Replacing the air filter regularly can eliminate this problem.

3. Dirty Condenser Coils

The condenser coils are located outside the home. That means they are exposed to the elements more than the indoor components of the air conditioner. Condenser coils can gradually gather a lot of dirt and debris that will turn into a thick coat of grime. When the condenser coil is too dirty, the dirt layer insulates it so the coil cannot carry out the heat exchange. This will cause your AC to overheat and repeatedly turn on and off. This can gradually lead to a complete breakdown and expensive repairs.
