Complete care for commercial plant.
Planned maintenance, fault finding and repairs for chillers, VRV/VRF systems, air handling units, fan coils, pumps and ventilation. Maintenance shaped around your plant, occupancy and operating priorities.
Maintenance, diagnosis and repairs across commercial refrigeration systems. We investigate temperature, control and plant faults, explain repair priorities and plan servicing around your operations.
Controls & BMS Diagnostics
Methodical fault tracing across plant, controls and BMS interfaces. We assess operating sequences, sensors and feedback, then document the fault and a practical repair pathway.
Plant Support & 24/7 Response
Cooling towers, ventilation, HVAC hygiene and mechanical plant support, with 24/7 assistance for commercial breakdowns. Clear condition reports help you prioritise defects, repairs and future asset replacement.
JSM specialises in mechanical Essential Safety Measures (ESM) for high-rise and commercial buildings. We inspect, test, maintain and report on relevant mechanical systems against each building’s maintenance schedule and applicable requirements, with practical coordination for occupied sites.
Diagnostic Case Study
At an occupied commercial building, JSM stabilised plant operation, traced unreliable feedback to incorrect status wiring and documented the permanent repair pathway.
Smoke Control & Pressurisation
Inspection, testing and maintenance of smoke-control, smoke-spill and stair pressurisation systems, scoped to the installed equipment and the building’s maintenance requirements.
Dampers & Fire-Mode Testing
Fire and smoke damper inspections, mechanical fire-mode testing and checks of relevant controls and interfaces. We coordinate with building management and other fire services contractors where integrated testing is needed.
Clear ESM Records
Inspection and test records, identified defects and recommended actions give building managers a clear maintenance trail. We help prioritise rectification and keep mechanical ESM documentation organised.
Occupied Building Expertise
Practical planning for access, shutdowns and tenant communication in high-rise and commercial properties. Facility managers, owners corporations and property managers work directly with experienced operators.
