AC system service in San Jose, CA

Nur HVAC completed a full AC system service at this San Jose, CA home, centered on replacing a failed compressor and restoring the refrigerant circuit. Because a compressor change touches the whole system, our technicians worked through it in careful stages rather than simply fitting a new part.

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

Stages of the job

• 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.

After a compressor fails, leftover oil and debris can travel through the lines and shorten the life of a replacement if they aren’t cleared out first. Flushing the lines, replacing the dryer, and leak-testing before recharging is what protects the new compressor and keeps the system from failing again soon after the repair. These steps are easy to skip but make the difference in how long the work holds up. Nur HVAC diagnoses the cause, works through the repair methodically, recovers refrigerant responsibly, and confirms the system is cooling properly before finishing the job.
