AC Compressor Replacement in San Mateo, CA
Compressor is the expensive part. We confirm with manifold gauges + clutch test + electrical check before quoting. Compressor + drier + system flush done together. From $700.
AC compressor failure is one of the more common AC repairs and one of the more expensive. Beacon Auto Care in San Mateo confirms compressor failure by manifold gauge readings, listens for internal damage, and checks for system contamination before quoting, because replacing a compressor on a contaminated system without flushing means the new one fails within months.
When We Recommend Replacement
- Clutch not engaging + no failure of clutch coil or wiring
- Internal noise: grinding, knocking from the compressor when AC is on
- Pressure readings out of spec: low-side high, high-side low (compressor not pumping)
- Metal debris in the system from a prior failure
- Internal seal leak verified by UV dye
What's Included on a Full Job
- OEM-equivalent or genuine OEM compressor with new clutch
- New receiver-drier or accumulator (always replaced with compressor)
- New expansion valve / orifice tube where applicable
- System flushed if prior failure debris is present
- Vacuum, leak check, refill to factory weight
- Usually a same-day job: most compressors done by 5 PM on a morning drop-off
- 24-month / 24,000-mile warranty on parts and labor
Not sure if it's the compressor? Start with AC leak detection or AC blowing hot.
