5 Signs Your Compressor Needs Maintenance (Before It Fails)

Your air compressor is an integral part of your operation — but like any piece of equipment, it needs regular maintenance to stay reliable and efficient. Ignoring early warning signs can lead to breakdowns, lost productivity, costly repairs, or injury.

Here are five key signs your compressor may need service — and how CLS can help keep your system running strong.

1. Unusual Noises

If your compressor starts making new or louder noises — like rattling, knocking, or hissing — it’s trying to tell you something. These sounds can indicate loose parts, worn bearings, or air leaks that need attention.

What to do: Don’t ignore it. Get it inspected before minor issues turn into major ones.

2. Decreased Air Pressure

If your tools or machines aren’t getting the pressure they need, your compressor could be struggling with leaks, filter clogs, or internal wear and tear.

What to do: Consistent air pressure is a must. A drop could signal a bigger problem that needs attention quickly.

3. Increased Energy Consumption

Seeing a spike in your utility bills? A compressor that’s working harder than it should due to blockages, inefficiencies, or mechanical issues will consume more energy — and cost you more every month.

What to do: Regular maintenance can help optimize performance and lower energy costs.

4. Excessive Heat or Moisture

If your compressor is running hot or producing more moisture than usual, that’s a red flag. Overheating can damage internal components, while excess moisture may mean your air dryer isn’t functioning properly.

What to do: Address it early to avoid damage to your equipment or end product.

5. Frequent Start-Stop Cycling

Compressors should maintain a steady cycle. If it’s constantly starting and stopping, you could be dealing with pressure switch issues, tank leaks, or electrical problems.

What to do: Don’t wait until it shuts down completely. A quick check can save you from a costly repair.
