Considered to be the heart of your truck’s air conditioning system, the AC compressor is a pump that moves the refrigerant across the AC system. Since the AC compressor is part of the air conditioning system, many people think that it compresses cold air, but it actually puts the refrigerant under high pressure and the cooling is done by other components in the air conditioning system before cold air reaches the passenger cabin.

Vehicle AC Compressor Problems vs. Low AC Refrigerant

Poor AC performance can often be traced back to either compressor failure or low AC refrigerant. Unfortunately, these vehicle components work hand-in-hand, making it hard to distinguish which is causing your AC troubles. So how can you tell if it is a compressor problem? There are a few subtle symptoms to look out for:

Freon Levels: If your AC system has optimal freon (refrigerant) levels (not too much or too little), but your air conditioner still does not work properly, this is often the sign of AC compressor failure.

Inconsistent AC Performance: Refrigerant leaks will only continue to get worse as the problem continues. On the other hand, a failing AC compressor might work well one day and poorly the next. While it is not applicable for all AC troubles, this symptom is an easy way to distinguish between low refrigerant and compressor problems.

Sudden AC Performance Drops: Refrigerant tends to leak gradually over time, while AC compressors can stop working on a dime. While even small refrigerant leaks can cause large AC problems, sudden drops tend to indicate compressor failure.

If you are still unsure of the source of your AC problems, it might be time to bring your vehicle to a mechanic for professional insight.
