There’s nothing worse than a failing car AC system, especially in the hot summer months in Arizona. How can you diagnose this problem and when is it obvious that your AC compressor is going bad?
Bad Car AC Compressor Symptoms
The compressor is the most essential component of a car AC system. The main functions of the compressor include the following:
- Moving air to the condenser.
- Pressurizing refrigerant to cool the air.
- Sensing temperature changes both inside and outside the car.
- Monitoring and controlling temperature output.
Below are five common causes of a bad or failing AC compressor in your car.
Odd Engine Compartment Sounds
An engine could be emitting odd noises for a variety of reasons. If, on inspection, you hear chirping, chattering, squealing, rattling, or whining sounds coming from your compressor’s area, it’s time for a professional AC service.
These types of noises will usually only erupt once the AC switch is engaged. The sounds could remain constant, though. A seizing or faulty clutch is typically responsible for the odd sounds. Failure can occur if the compressor oil used for lubrication is insufficient, the wrong type, or becomes contaminated.
Noticeable Compressor Damage
Physical damage to the compressor or its clutch can be a clear sign of an internal issue with your AC. This can also apply to corrosion.
Oftentimes, moisture is the enemy of any AC system, which means corrosion is likely a sign of an internal problem. Oil leaks can also lead to compressor breakdown. Take your car in for an inspection if you notice any visible damage in this area.
AC Not Working Properly
One of the most obvious signs of a compressor issue is when the air coming into the car’s cabin is not as cold as it should be.
Of course, there are other problems related to the AC system that can produce warmer air, but a failing compressor is the most likely culprit. You can have the air temperature tested to know if it should be lower than it currently is in your cabin.
Compressor Clutch Won’t Engage
When turning on the AC, the clutch attached to the pulley on your compressor will engage. The clutch appears as a plate featured on the front of the pulley. When the AC is turned off, the clutch will not spin.
The clutch may make a momentary click and start spinning with the belt and pulley when the AC is turned on. When the clutch fails to engage, the compressor should be serviced. It should also be inspected if it makes a whining or screeching noise when engaged.
Other AC Compressor Related Concerns
The compressor is not the only component of an AC system that can fail or deteriorate as time goes on. Other problems within an AC system that are related to the compressor include the following examples:
- Refrigerant loss.
- Refrigerant blockage.
- Faulty blower motor.
- Worn out or broken serpentine belt.
- Blown fuse.
- Clogged cabin air filter.
