AC pulleys are the unsung heroes of your car’s air conditioning unit. A broken compressor pulley doesn’t just reduce cooling; it could even damage the engine.

But are damaged pulleys expensive to replace?

B. Factors Affecting Cost

Is It Worth Replacing the AC Pulley?

Yes, because a faulty air conditioning compressor pulley can damage many different parts of your car, starting with the AC unit. A bad AC can increase the cabin humidity and fog up your windows, making it hard to see where you’re going.

But that’s just the start.

A faulty compressor pulley can also impact its surrounding parts, such as its bearing, expansion valve, and clutch coil. It can lead to compressor failure, resulting in a hefty repair bill. And if the pulley hasn’t been spinning properly for a long time, it could stop completely and shred the serpentine belt.

Consequently, a broken pulley could damage the engine. The engine powers the belts and the attached pulleys. So when these parts don’t function properly, the engine has to work hard to keep them running, potentially shortening its lifespan.

Signs You Need an AC Pulley Replacement

You may need to call a mechanic if you notice any or all of these symptoms:

  1. AC unit isn’t cooling properly
  2. Loud squealing noise, followed by a stalled engine
  3. Engine smelling like burnt rubber
  4. AC compressor belt coming off or slipping
  5. Compressor overheating very quickly

How Long Do AC Pulleys Last?

A new AC compressor pulley can last as long as your car. However, it can wear out quicker than usual if you constantly use your air conditioner for longer periods (especially in hot temperatures). 

Here are a few ways to prevent damage to your new compressor pulley:

Do You Need to Replace the Compressor Clutch Along with the AC Pulley?

Yes, you may have to replace the compressor clutch, especially if you’ve driven with a broken AC pulley for a long time.

Let us explain.

The pulley ensures a smooth power transfer from the engine to the AC clutch. If the pulley malfunctions, the compressor may experience uneven and excessive loads, causing its clutch to engage and disengage more frequently. This will wear it out faster.

One surefire way to know if you need an AC clutch replacement is to look for a burning smell coming from the central AC unit — a sign that the clutch has melted. This happens because the pulley would have overheated and transferred the heat to the clutch.
