AC system repair in San Jose, CA

Nur HVAC carried out a major AC system repair at this San Jose, CA home, replacing a failed compressor and rebuilding the refrigerant circuit around it. A compressor swap is involved work, so our technicians took the steps needed to protect the rest of the system rather than simply dropping in a new part.

The job ran from recovering the old refrigerant through to pressure-testing and recharging the system, leaving the air conditioner ready to cool reliably again.

What our technicians did

• Recovered the old refrigerant: removed the existing freon for proper recycling.
• Removed the old compressor: cut out and dismantled the failed compressor for recycling.
• Flushed the lines: cleared old oil from the copper refrigerant lines.
• Replaced the filter dryer: fitted a new filter dryer to keep moisture and debris out of the system.
• Leak-tested with nitrogen: pressurized the system with compressed nitrogen to check for leaks.
• Recharged the system: filled the circuit with fresh refrigerant to the correct level.

When a compressor fails, debris and old oil can spread through the lines and damage a replacement before it has a chance to settle in. Flushing the lines, replacing the dryer, and leak-testing before recharging is what keeps the new compressor running long-term rather than risking a repeat failure. Skipping those steps is a common reason a fresh compressor doesn’t last. Nur HVAC diagnoses the cause, works through the repair methodically, recovers refrigerant responsibly, and confirms the system is cooling properly before finishing the job.
