5 Signs Your AC Compressor Has Problems


If you’re a homeowner in Florida and you’re not familiar with what a compressor is, you should know why this component is essential to your AC’s functionality. Not only is a well-functioning compressor essential to your AC’s performance, but it’s also the most expensive component of the system. 

The compressor is often called the “heart” or “engine” of the AC system. It pumps and pressurizes the refrigerant so that it can perform the evaporation and condensation needed to cool the air. As your AC system ages, the compressor is in danger of failing. That’s why it’s important to know the signs of a failing compressor and when to call for AC repair in Riverview, FL.

1. The Unit Vibrates When It Starts Up

The compressor resides in the outdoor unit of your AC system. If your AC unit vibrates or shakes every time it turns on, this is referred to as “hard starting.” This happens when the compressor needs to draw on extra power to overcome resistance when it tries to power on. Hard starting puts massive strain on the compressor and may cause it to burn out completely if the problem isn’t addressed promptly. 

2. Clicking or Ticking Sound

If you hear these noises when your AC powers on, it could be a sign that your unit doesn’t have the power needed to boot up. This often indicates there’s a problem with an electrical component such as a relay or a capacitor. If this goes on, the compressor may not come on at all. Clicking noises from the compressor could also be something as simple as a loose bolt.

3. Tripped Circuit Breaker

Let’s say the compressor manages to power on but then shuts down because it has tripped a circuit breaker in your home’s electrical panel. This is a major warning sign that the compressor motor is overheating which causes it to draw too much power. You may be tempted to just reset the breaker and hope for the best. However, we don’t recommend doing this as it’s likely to cause the compressor to fail completely. 

4. Rattling or Rumbling Noise

If you hear these sounds from the compressor, it could be caused by loose internal mounts or that the motor has come loose and is moving around and rattling around inside the compressor. You’ll also notice that your AC’s performance has decreased. This should be a relatively minor fix from our team and requires securing these parts down. 

5. Decreased Cooling Capacity

Because the compressor is the main part responsible for compressing refrigerant, when it starts to fail, that obviously means your AC can no longer function properly. That’s why you’ll notice a decrease in your AC’s cooling capacity. Although there are other possible causes for this, if you notice it with any of the other symptoms, you should call us promptly. 

Whether it’s an immediate compressor issue or you think your AC just isn’t working as it should, we’ll be glad to send someone out quickly to diagnose the problem and perform any necessary repairs.
