Buyer's checklist
What to check before buying a used A/C compressor
- Spin the clutch hub by hand — it should rotate smoothly without grinding or seized bearings.
- Check that the refrigerant ports are capped. An open compressor may have absorbed moisture, which damages the system.
- Match the compressor type (scroll, swash plate, or variable displacement) to your vehicle's spec.
- Budget for a new receiver/drier and expansion valve — shops recommend replacing these whenever the system is opened.
