Subaru AC Compressor Replacement Cost
Full replacement of the A/C compressor, system evacuation, and refrigerant recharge.
Why this fails
Most commonly caused by premature failure of the internal swash plate or a leaking shaft seal, particularly on FB20 and FB25 engines. High-mileage units often suffer from magnetic clutch failure where the coil burns out and fails to engage the pulley.
What the job involves
- Recovering existing R134a or R1234yf refrigerant using a specialized recovery machine.
- Removal of the serpentine drive belt and disconnecting electrical connectors.
- Disconnecting high and low-pressure AC lines and removing the mounting bolts to extract the old compressor.
- Installing the new compressor with new O-rings lubricated with PAG oil.
- Performing a vacuum leak test on the system for 30+ minutes to ensure no leaks and remove moisture.
- Recharging the system to factory weight specifications with fresh refrigerant and UV dye.
If you delay this repair
A seizing compressor can snap the serpentine belt, leaving you stranded without power steering or an alternator. If the compressor 'grenades' internally, it will send metal shards throughout the entire A/C system, increasing repair costs to over $3,000 to replace the condenser and evaporator.
Save money
- • Verify if your vehicle is covered under Subaru's extended TSB warranty (certain 2015-2018 models had a 10-year factory warranty extension on the compressor).
- • If the clutch is the only failure point, some independent shops can replace just the clutch/pulley assembly (Part #73121FJ000) for $350-$500 total, rather than the whole compressor.
- • Ask the shop to use a 'New Aftermarket' unit from a reputable brand like Denso (the OEM manufacturer for Subaru) to save $300+ over the Subaru-boxed part.
