If your air conditioner is turning on and off frequently, there are a few possible reasons this might happen. This blog post will explore five of the most common reasons why an air conditioner turns on and off suddenly. Our team at Aircond Xpert JB will also provide tips on avoiding these issues.
Is It Normal For Aircon To Suddenly Turn Off And On?
No, it is not normal for your air conditioner to turn on and off frequently. If your air conditioner is doing this, it could be a sign that something is wrong. There are a few possible reasons why your air conditioner might be turning on and off suddenly. We will explore some of these reasons below.
1. Dirty Air Filter
One of the most common reasons why an air conditioner turns on and off suddenly is because the air filter is dirty. The air filter is responsible for trapping dirt, dust, and other airborne particles. over time, these particles can build up on the filter, causing it to become clogged. When this happens, the airflow to the evaporator coils is restricted, which can cause the coils to freeze. As a result, your air conditioner will cycle on and off frequently in an attempt to thaw the coils.
You should clean or replace your air filter every 1-3 months to prevent this from happening. If you have pets or live in a dusty area, you may need to do this more often.
2. Thermostat Issues
Another common reason for an air conditioner turning on and off frequently is thermostat issues. If your thermostat is not set correctly, it can cause your air conditioner to cycle on and off more frequently than normal. The most common issue is that the thermostat is set too low. When this happens, the air conditioner will turn on and cool the room to the desired temperature, but it will turn off before it gets too cold. As a result, the room will quickly heat up again, causing the air conditioner to cycle on and off more frequently.
You will need to adjust the thermostat to a higher setting to fix this problem. You may also need to replace the batteries in your thermostat if it is not working properly.
3. Refrigerant Leaks
Another possible reason for your air conditioner turning on and off frequently is refrigerant leaks. Refrigerant is what helps your air conditioner remove heat from the air. Over time, however, leaks can develop in the refrigerant lines. When this happens, the air conditioner will not be able to remove enough heat from the air, causing it to cycle on and off more frequently.
To fix this problem, you will need to have a professional repair the leaks and recharge the system with refrigerant.
4. Incorrectly Sized Unit
Another common issue that can cause your air conditioner to turn on and off frequently is an incorrectly sized unit. If your air conditioner is too small for the room, it will have to work overtime to cool the space. As a result, it will cycle on and off more frequently than normal. On the other hand, if your air conditioner is too big for the room, it will cool the space too quickly and then turn off before it can remove all the humidity. This can also cause the unit to cycle on and off frequently.
To find the correct size air conditioner for your room, you will need to consider the square footage of the space and the number of windows in the room. You can use this information to calculate the BTU (British Thermal Units) required to cool the space. Once you have this number, you can choose an air conditioner with the correct cooling capacity.
5. Dirty Condenser Coils
The condenser coils are responsible for releasing heat from the refrigerant. Over time, however, these coils can become dirty, which can prevent them from releasing heat properly. When this happens, the air conditioner will have to cycle on and off more frequently in order to cool the space.
To clean the condenser coils, you will need to turn off the power to the unit and remove the fan blade. Once you have done this, you can use a brush or cloth to clean the coils. Be sure to also remove any debris that has accumulated around the coils.
