Chilled Water Units & Air Cooled Chillers

Rooftop chiller coil service

Challenge
Reduced airflow across a rooftop chiller coil was pushing discharge pressures higher than normal, risking a nuisance trip during peak demand.
Approach
Isolated the unit safely, pressure-washed the coil face, checked fan operation and verified pressures against the equipment nameplate.
Outcome
Coil airflow and running pressures returned to normal range, reducing near-term trip risk.

Air-cooled chiller diagnostics

Challenge
A corporate site reported inconsistent chilled water temperatures affecting comfort on upper floors.
Approach
Connected gauges to the chiller circuit, checked refrigerant charge and reviewed control setpoints against the building schedule.
Outcome
Identified the corrective action required and provided a written diagnostic report for the facilities team.

Cooling Tower Servicing

Cooling tower delivery and installation

Challenge
An ageing cooling tower needed replacement without extending plant downtime longer than necessary.
Approach
Coordinated crane delivery and safe rigging of the new tower, then positioned and secured it on the elevated support platform.
Outcome
New cooling tower unit landed and secured on schedule, ready for pipework connection and commissioning.

Compressor Repairs

Compressor rigging and replacement

Challenge
A failed compressor needed careful rigging and removal in a tight site access area.
Approach
Planned the lift with a three-person crew, used a gantry hoist to extract the old unit and positioned the replacement compressor safely.
Outcome
Compressor swapped without damage to surrounding pipework or structures, ready for reconnection.
HVAC Technologies technician inspecting a rooftop BMS control panel
BMS Maintenance

BMS and control panel review

Challenge
Rooftop control panel wiring and schedules had not been reviewed in some time, raising the risk of undetected faults.
Approach
Opened and inspected the control panel, checked wiring terminations and verified schedule and sensor behaviour against building hours.
Outcome
Confirmed panel condition and corrected schedule mismatches found during the inspection.

Industrial plant room support

Challenge
A production facility needed a multi-person team to service business-critical plant room equipment on a tight window.
Approach
Deployed a full crew for coordinated pump, valve and compressor inspection work across the plant room during a planned shutdown.
Outcome
Plant room work completed within the shutdown window with documented findings for the client's engineering team.
