For commercial buildings where centralised air distribution is required, QPT designs and installs ducted air conditioning systems with supply and return air ductwork, diffusers, zone dampers, and BMS integration.
Ducted systems suit open-plan commercial spaces, hospitality venues, and buildings where a single outdoor unit can serve an entire floor or zone.
Packaged rooftop units provide integrated cooling and ventilation from a single piece of plant on the roof, with ducted distribution to the occupied space below. QPT installs packaged units for retail centres, warehouses, and commercial buildings where a self-contained solution is preferred. For commercial aircon in Brisbane’s retail and warehouse sector, packaged units are a cost-effective and proven approach.

For large commercial buildings, central chilled water plant delivers cooling from a central plant room to distributed air handling units and fan coil units across the building. Chilled water systems are the standard solution for A-grade and large-format commercial buildings, and the most energy-efficient option at scale. QPT designs and installs central chilled water systems including chillers, cooling towers, and distribution pipework as part of the HVAC installation for Brisbane commercial building projects.

Commercial air conditioning systems require regular preventative maintenance to maintain performance and system life. Neglected systems consume more energy, break down more frequently, and fail earlier. QPT provides planned maintenance programmes for all system types, structured as quarterly, half-yearly, or annual service agreements depending on system type and occupancy requirements.
