What Causes The Air Conditioner To Short Cycle?

There is probably something wrong with your air conditioning unit if it frequently cycles on and off, known as short-cycling. This can be because a component is dirty, broken, or not functioning properly. In this scenario, the issue should be addressed and not left unattended.

When it comes to your air conditioning system in Port Charlotte, FL, you don’t want to be wasting money and energy on a system that will need to be replaced sooner rather than later. If your air conditioner is cycling on and off frequently, you should have a qualified HVAC technician come out as soon as possible to inspect the problem.

Causes of Short Cycling

Identifying the source of your short cycling problem is the first step in fixing it. There are numerous reasons why an air conditioner may short cycle.

Incorrectly Sized System

One of the most common causes of AC short cycling is incorrect sizing of the AC unit. Short cycling can occur if your room’s cooling system is too large. It will send out too much cool air, which will cause the air conditioner to turn off quickly. This results in higher utility costs, more service calls, and uneven cooling in the home. Replacement of your air conditioner is the best option in this situation.

Low Refrigerant

Low refrigerant levels mean your air conditioner has to work overtime to cool your space. This will stress different parts of the system and make them work harder, ultimately leading to malfunctions and short cycling. Because the pressure in your AC system is too low, your compressor will shut down.

Electricity Problem

Short cycling can be caused by problems with the wiring or the control boards. Faulty electrical connections can cause your unit to shut down prematurely and shorten its life cycle, resulting in malfunctioning. Loose connections can also cause short cycling. It’s best to call an expert as soon as you notice an electrical problem so that they can provide you with the assistance you need to do so safely.


When your system has a broken compressor, dirty filters, dirty coils, or insufficient refrigerant, it blocks the flow of air and has to work harder to cool your room. As a result, your AC may overheat. Your compressor will also malfunction if you have an overcharged system. A lack of airflow can lead to overheating of motors.

Fixing Short Cycling

Short cycling can cost you a lot of money in the long run. Solving this issue quickly is a wise decision. Maintaining your Air Conditioning Systems in Port Charlotte, FL and HVAC system regularly is the simplest and most effective way to avoid short cycling.
