Having an air conditioner compressor fail can be a stressful and costly experience. To help you avoid a potential breakdown, it is important to know the five most common causes of air conditioner compressor failure. In this blog post, we will explore the top five causes of air conditioner compressor failure so that you can better prepare for any potential issues with your unit.

Overheating
When an air conditioner’s compressor is running for long periods or under extreme temperatures, it can cause the compressor to overheat and eventually burn out. To prevent this, homeowners should make sure their air conditioner’s filters are clean and that the unit is not being overworked. It is also important to make sure the area around the air conditioner compressor is properly ventilated and that the compressor isn’t exposed to direct sunlight.
Electrical Issues
Electrical issues can be one of the leading causes of air conditioner compressor failure. A few common electrical problems that can cause the compressor to fail to include a defective capacitor, faulty wiring, or an overloaded circuit. A capacitor is a device that stores energy and helps the air conditioner compressor to start up. If this capacitor becomes defective, the air conditioner compressor may not have enough power to kick on, failing.
Refrigerant Leaks
Leaking refrigerant is one of the most common causes of air conditioner compressor failure. If a refrigerant leak occurs, it can cause the compressor to overheat and eventually fail. The leak might be from a damaged line or from a worn-out gasket, which is typically located on the air conditioner compressor. If the air conditioner compressor is leaking, it is important to have it repaired as soon as possible to avoid further damage and potential compressor failure. The repair technician will likely inspect the compressor for any signs of a refrigerant leak and replace the damaged parts if necessary.
Clogged Filters
One of the most common causes of air conditioner compressor failure is a clogged filter. If the air filters are not regularly replaced or cleaned, dust, dirt and other debris can accumulate, reducing the efficiency of the compressor and causing it to overwork. This can lead to damage and eventually failure. Clogged filters can also cause your AC unit to freeze up or lose its cooling capacity, making it difficult for the compressor to circulate the coolant. To avoid this problem, make sure to check and change your air filters at least once a month.
Improper Installation
When installing an air conditioner compressor, it is important to follow the manufacturer’s guidelines exactly. If done incorrectly, it can cause serious damage to the unit and result in an air conditioner compressor failure. Poorly installed compressors are vulnerable to several problems, including vibrations that can cause parts to wear out or break. Additionally, if the compressor isn’t securely attached to the mounting plate, the internal parts may move around and cause issues. It is also important to use the proper wiring, seals, and connectors when connecting the compressor to other components in the system. Failure to do so can result in poor performance, electrical shorts, and other issues.
Conclusion
An air conditioner compressor is an important part of a properly functioning HVAC system. If an air conditioner compressor fails, it can lead to a costly repair or replacement of the unit. Knowing the most common causes of air conditioner compressor failure can help you stay ahead of potential issues and keep your HVAC system running smoothly. The five most common causes of air conditioner compressor failure are overheating, electrical issues, refrigerant leaks, clogged filters, and improper installation. By addressing these issues promptly and scheduling regular maintenance, you can ensure that your air conditioner compressor continues to run reliably and efficiently.
