4 Reasons Your Home A/C is Overheating and Shutting Down

As the temperatures rise, we rely on our air conditioning units to keep us cool and comfortable. But what happens when your A/C suddenly shuts down? This can be frustrating and uncomfortable, especially during the hot summer months. In this article, we’ll explore four common reasons why your home A/C may overheat and shut down.

1. Dirty Air Filters

One of the most common causes of an overheating A/C unit is dirty air filters. Over time, air filters can become clogged with dust and debris, restricting airflow through the system. When this happens, the unit has to work harder to cool your home, leading to overheating and possible shutdown. To prevent this issue, it’s important to regularly clean or replace your air filters every one to three months. By calling in professionals for air conditioning units in Atlanta, you can ensure that your filters are kept clean and in good condition.

2. Blocked Condenser Coils

Another potential cause of an overheating A/C unit is blocked condenser coils. The condenser coils are located in the outdoor unit and are responsible for releasing heat from the refrigerant as it circulates through the system. If these coils become covered in dirt or debris, they can’t release heat effectively, causing the unit to overheat and shut down. To avoid this issue, make sure that there is no debris around your outdoor unit and that it has enough clearance from walls or other objects.

3. Low Refrigerant Levels

Low refrigerant levels can also cause an A/C unit to overheat and shut down. Refrigerant is responsible for absorbing heat from inside your home and carrying it outside to be released by the condenser coils. When refrigerant levels are too low, the system can’t remove heat effectively, causing it to overheat and potentially shut down completely. If you suspect that your refrigerant levels are low, contact a professional HVAC technician for assistance.

4. Faulty Components

Finally, faulty components, such as a malfunctioning compressor, can cause an A/C unit to overheat and shut down. The compressor is responsible for compressing and circulating the refrigerant throughout the system, and if it’s not functioning correctly, it can cause the unit to overheat. So, if you suspect that your A/C unit is overheating due to a faulty component, then check the system in an effort to identify the issue. It will also help if you learn the energy efficient AC settings to be able to save your electricity bills and keep your home comfortable.

To Conclude

An A/C unit that shuts down due to overheating can be both uncomfortable and annoying. Fortunately, the four most common causes of an overheating A/C unit are all relatively easy to prevent or fix. Whether it’s due to a dirty air filter, blocked condenser coils, low refrigerant levels, or a faulty component, understanding the cause of your A/C unit’s shutdown can help you get it running smoothly again.
