Conduct safety checks, system testing and performance verification prior to handover.
Maintenance, Servicing & Optimisation
Perform planned preventative maintenance (PPM) on temporary HVAC plant in line with operational standards.
Carry out refrigerant checks, burner tuning, combustion analysis, pressure testing and system balancing.
Complete heat exchanger inspections, pump maintenance, filter changes, valve checks, and electrical testing.
Use remote monitoring systems (where applicable) to diagnose faults early and optimise system performance.
Fault-Finding & Technical Support
Respond to emergency breakdowns, identifying mechanical, electrical, refrigeration or combustion-related issues.
Conduct thorough diagnostics on chillers, boilers, pumps, control panels, sensor networks and ancillary equipment.
Implement safe, efficient repairs to restore system performance quickly.
Provide expert technical advice to clients on operational best practice and system care.
Operational Support & Documentation
Assist with the mobilisation and demobilisation of temporary plant, including equipment positioning and connection.
Produce accurate engineering reports, job sheets, risk assessments and commissioning records.
Maintain the highest standards of health & safety, adhering to site rules and engineering best practice.
Contribute to a 24/7 operational rota, providing out-of-hours response when required.

Strong understanding of relevant standards, safety protocols and compliance frameworks.
Full UK driving licence required.
Core Competencies
Excellent fault-finding ability across multiple disciplines.
Strong awareness of safety, risk and correct engineering procedure.
Able to work independently on complex systems with minimal supervision.
Confident in client-facing environments with clear communication skills.
Comfortable working in fast-paced, reactive field-based environments.
