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.

Test car air conditioning compressor

1. Start by visually inspecting the compressor for any signs of damage or leakage.

2. Measure the voltage at the compressor's electrical connector using a multimeter to ensure it is receiving power.

3. Check the clutch engagement by turning on the air conditioning and observing if the compressor clutch engages and spins freely.

4. Use a manifold gauge set to check the high and low side pressures. Compare the readings to the manufacturer's specifications to determine if the compressor is functioning properly.

5. If all other tests indicate a fault with the compressor, it may need to be removed and taken to a qualified professional for further testing and repair.

The automobile air conditioning compressor is the core component of the automobile air conditioning system and plays a key role in driving the refrigeration cycle. It achieves rapid cooling of the air in the car by compressing low-pressure cold gas into high-pressure and high-temperature gas. A high-quality compressor provides efficient refrigeration capacity, which can reduce the temperature inside the car in a short time and provide a comfortable driving experience.

At the same time, it must have the characteristics of low energy consumption, low noise and reliability to ensure the long-term stable operation of the air conditioning system. The performance of the automobile air conditioning compressor directly affects the working effect of the entire air conditioning system. Choosing a high-performance and reliable compressor will bring a more comfortable driving experience to the driver.
