6 Signs Your Car Air Conditioning Compressor is Failing
As Brisbane’s summer temperatures soar, a functioning car air conditioning (AC) system is essential for comfortable driving. The compressor, the heart of your car’s AC system, circulates refrigerant and maintains system pressure. When it starts to fail, your AC’s performance can suffer significantly. Recognising these car AC compressor signs early can help you address issues before they lead to more extensive and costly repairs.
Here are the 6 most common signs that your car air conditioning compressor is failing:
1. Unusual Noises
Grinding or Squealing Sounds
One of the clear car AC compressor signs is grinding or squealing sounds when the AC is on. This could indicate worn-out or damaged internal components, often due to failing bearings or lack of lubrication.
Clunking or Rattling
These noises may suggest loose or broken parts inside the compressor, potentially signalling imminent failure.
2. Reduced Cooling Performance
Weak Airflow
If the airflow from your car’s vents is weak, the compressor may be struggling to maintain the necessary pressure to circulate refrigerant effectively.
Warm Air
When your AC blows warm air instead of cool, it’s a clear sign that the compressor isn’t functioning properly.
3. Fluid Leaks
Refrigerant Leaks
Look for oily spots or puddles under your car, especially near the front, which could indicate refrigerant leaks from a failing compressor.
Oil Leaks
Leaking compressor oil can lead to reduced lubrication and further damage to internal components.
4. Electrical Issues
Compressor Clutch Not Engaging
If the compressor clutch isn’t engaging, it could be due to an electrical issue or a failing compressor, resulting in a lack of cooling.
Blown Fuses or Tripped Circuit Breakers
Frequent electrical issues might indicate an overworked or failing compressor drawing too much power.
5. Unpleasant Smells
Burning Smell
A burning smell from the AC vents can indicate an overheating compressor, potentially due to internal damage or insufficient lubrication.
Musty Odour
A musty odour could signal moisture build-up due to a malfunctioning compressor, potentially leading to mold and mildew growth.
6. Visible Damage
External Corrosion
Visible rust or corrosion on the compressor’s exterior can indicate internal damage or wear.
Seized Compressor
If the compressor pulley turns freely when the engine is off, or doesn’t turn at all when the engine is running, the compressor may have seized.
