Refrigeration Services

Sambar Electrical and refrigeration provides comprehensive HVACR and refrigeration solutions across Northland, Auckland, Waikato and Bay of Plenty - specialising in refrigerated containers, commercial refrigeration systems, cold storage, and process cooling applications.
We ensure thermal reliability, energy efficiency, and full operational continuity for clients who depend on precision-controlled environments.

24/7 Emergency Breakdown Response

Temperature control failures require immediate attention. Our 24/7 rapid-response team is equipped to diagnose and repair refrigeration faults at any hour.
Each technician carries essential diagnostic instruments, refrigerant gases, electronic leak detectors, and replacement components, enabling on-site rectification and system reinstatement without delay.

Tier 1 Priority Servicing

Our Tier 1 Service Agreements are structured for mission-critical operations. These contracts provide priority dispatch, dedicated technician allocation, and guaranteed response times during high-demand periods.
Tier 1 clients are placed at the top of our service hierarchy - ensuring operational continuity even during peak call volumes.

Preventative Maintenance & Performance Auditing

We implement preventative maintenance schedules aligned with system load profiles, manufacturer recommendations, and site conditions.
Each service includes:

• Compressor performance verification and current draw analysis

• Refrigerant charge balance and superheat/subcooling measurement

• Evaporator and condenser efficiency checks

• Electrical integrity testing and contactor inspection

• Defrost system and air distribution assessment

• Door gasket, seal, and insulation integrity review

This proactive approach ensures optimal coefficient of performance (COP), reduced compressor cycling, and extended asset lifespan.

Technical Reporting & Compliance Documentation

After every service or repair, clients receive a comprehensive service report including:

• Recorded pressures, temperatures, and amperage readings

• Identified component wear or degradation

• Recommendations for remedial actions

• Compliance references for audit and insurance documentation

All records are maintained for traceability under New Zealand refrigeration compliance standards.

Spare Parts & Component Availability

Our service fleet and regional depot maintain an inventory of critical refrigeration components - including TX valves, solenoids, sensors, contactors, controllers, and pressure switches.
This ensures rapid turnaround for repairs and eliminates delays caused by parts sourcing.

System Optimisation & Efficiency Upgrades

We conduct system performance analysis to identify energy inefficiencies, refrigerant imbalances, and airflow restrictions.
Through calibrated system tuning, retrofitting, and control adjustments, we improve energy performance ratios (EER) and reduce operational costs.

Scheduled Servicing Coordination

Maintenance intervals are coordinated around client logistics and operating schedules.
We service equipment during non-critical windows to avoid disruption to cold chain integrity and production processes.

Certification & Regulatory Compliance

All work performed by Sambar Electrical adheres to AS/NZS 1677, NZ Building Code G9, and manufacturer specifications.
We provide leak testing certification, refrigerant handling compliance, and complete maintenance documentation to meet audit, insurance, and site safety standards.
