How To Tell if Your AC Compressor Is Bad

Are you experiencing an AC system that isn’t working as well as it used to? It could be that your AC compressor is failing. The compressor is a key component of your AC system and is responsible for circulating coolant and pressurizing the refrigerant. There are several signs that your AC compressor is failing, from loud noises to a decrease in cooling power. Keep reading to learn more about how to tell if AC compressor is bad.

Rattling or Banging Noise

A rattling or banging noise coming from your air conditioner compressor can be a sign that it is failing. The compressor is the heart of the air conditioning system, as it circulates refrigerant throughout the unit to absorb and release heat. When the compressor starts to fail, it can make loud noises that can be heard inside and outside of the home. Loose or broken parts inside the compressor, such as the fan blades, fan motor, or compressor motor, typically cause this noise.

The rattling or banging noise is usually accompanied by a decrease in cooling capacity and other symptoms, such as a lack of airflow, a decrease in air pressure, or an increase in energy costs. If this noise is heard, it is important to have the compressor inspected by a professional AC technician as soon as possible. If the compressor is failing, repairs or replacement may be necessary in order to keep the air conditioning system running properly and efficiently.

Reduced Airflow

Reduced airflow and cooling power are signs that your AC compressor is failing. When your AC compressor is failing, it can cause the air coming out of your vents to be less powerful than normal. This is due to the fact that the compressor is unable to move enough refrigerant through the system, which is necessary for it to cool effectively. It is also possible that the compressor may be failing due to a lack of lubrication, as this is essential for it to run correctly. When the lubrication becomes low, it causes the compressor to overheat, which can lead to reduced airflow. Additionally, the compressor may be failing due to a blockage in the system that can also limit the amount of air that is able to move through it. It’s important to have your AC unit checked as soon as possible if you notice reduced airflow and cooling power.

Circuit Breaker Tripping

Circuit Breaker Tripping

Circuit breaker tripping is one of the most common signs of a failing air conditioning compressor. When the compressor malfunctions, it could cause the circuit breaker to trip, shutting off the power to the compressor and preventing it from continuing to run. The most common reasons for a circuit breaker tripping are an overload of electricity or a short circuit. This happens when there is too much current flowing through the compressor, which a faulty compressor or damaged wiring connections can cause.

If a circuit breaker trips, it is important to shut off the power to the air conditioning unit and contact a professional for repairs. A qualified technician can inspect the unit and diagnose the problem, and then make any necessary repairs.

Unit Vibrations

When an air conditioning unit starts up, it is normal to feel a slight vibration. However, if the vibration is strong or lasts longer than usual, it may be a sign that your AC compressor is failing. Vibration is caused by an imbalance in the compressor’s motor, which can be caused by worn-out or loose parts or can be the result of an issue with the compressor’s cooling system. A vibrating AC unit is an indication that it is not functioning correctly and needs to be serviced. Ignoring the problem could lead to further damage and costly repairs.

While some signs or more obvious than others, there are numerous indications that your AC compressor is failing, and it is important to pay attention to them in order to prevent serious damage to your air conditioning system. Ignoring these signs can lead to costly repairs and a decrease in the efficiency of your air conditioning system.
