Air conditioning & VRV/VRF
Split, multi-split and VRV/VRF servicing, installation, leak investigation and repairs.
COMMERCIAL HVAC
Commercial air conditioning & refrigeration specialists.
Planned servicing, performance investigation and repairs across interconnected commercial HVAC and mechanical systems.
Chillers & refrigeration
Refrigerant circuit diagnostics, compressor work, heat exchangers and cooling plant replacement.
Ventilation & air handling
AHUs, fans, motors, filters, drives and mechanical ventilation systems.
Heating & mechanical
Pumps, valves, heat exchangers, pressurisation equipment and associated plant.
Controls & fault finding
Electrical control circuits, interlocks, plant operation and connected-system diagnosis.
Plant replacement
Planned equipment and component replacement with attention to site requirements.
An engineering-led response
Complex HVAC faults can involve more than one system. We look at operating conditions, controls, refrigerant circuits and mechanical components before recommending a repair.
For examples of the equipment and work involved, explore our project photography.
ENGINEERING CAPABILITIES
Commercial plant, understood.
Technical investigation and practical remedial work across connected building systems.
VRV / VRF & DX cooling
Fault tracing across indoor and outdoor units, refrigerant circuits, communications, expansion devices and system controls.
Chillers & cooling plant
Performance investigation, pressure and temperature assessment, leak detection, component replacement and planned plant renewal.
Ventilation & air handling
Fan and motor issues, filters, belts, drives, air handling components and ventilation performance.
Heating & water-side systems
Pumps, valves, heat exchangers, pressurisation units, distribution pipework and associated heating plant.
Refrigeration engineering
Refrigerant circuit integrity checks, recovery, pressure testing, evacuation and repairs where appropriate.
Electrical controls & interlocks
Tracing control circuits, proving inputs and outputs, investigating relay, contactor and equipment enable conditions.
OUR APPROACH
Find the cause. Not just the symptom.
Intermittent shutdowns and poor performance can involve controls, airflow, water flow or refrigerant circuits. QMES takes a systematic approach to testing and reporting, with recommendations based on observed conditions.
