Frequently Asked Questions (FAQs)
1. How do I know if my AC compressor bearing is bad?
You can identify a bad AC compressor bearing by the high-pitched squeal or grinding sound of metal-on-metal. If the bearing seizes, it can cause the drive belt to squeal as it is unable to spin the compressor.
2. Can you just replace a bearing on an AC compressor?
Replacing bearings in the AC compressor usually requires removing the end plate, which releases the refrigerant. It is often more efficient to remove the compressor and work on it separately. One common issue is the clutch bearing failure.
3. What happens when the AC compressor bearing fails?
When the AC compressor bearing fails, the bearing race will spin on the front of the compressor, damaging the compressor assembly case. To fix the issue, the entire compressor assembly needs to be replaced. Additionally, a seized pulley can cause the belt to break or make a squealing noise.
4. Can I drive with a bad AC compressor bearing?
Driving with a broken AC compressor is not recommended. While it may be possible to drive with a broken AC compressor without immediate expensive repairs, it can cause further damage to the engine and potentially impact your health.
5. What causes compressor bearing failure?
Compressor bearing failure is often caused by liquid refrigerant diluting the lubrication oil, preventing proper lubrication to the crankshaft, conrods, and bearings. This leads to the bearings seizing.
6. How much does it cost to replace AC clutch bearings?
The cost of replacing AC clutch bearings can vary, but the average cost ranges between $593 and $644. This includes labor costs estimated between $187 and $235, and parts priced between $406 and $409.
7. What is the most common reason that an AC compressor will fail?
Common causes of AC compressor failure include power surges, compressor overheating, and dirty AC coils.
8. What does a bad AC compressor bearing sound like?
A bad AC compressor bearing can produce a squealing or grinding noise as metal rubs against metal within the fan motor. This noise is more common in older air conditioners with belt-driven blowers and condenser fan units.
