PSB Air partnered with Shape and Ausgrid to complete a major commercial air conditioning retrofit at the Ourimbah facility. The project involved a full retrofit of existing pipework, installation of air-cooled VRF air conditioning systems, and upgrades to the building’s mechanical ventilation. The goal was to improve efficiency, enhance comfort, and ensure long-term system reliability.
Refining an Existing System for Better Performance
This project required more than a standard air conditioning installation. It demanded precise re-engineering of an existing system. During the initial inspection, the PSB Air team identified issues with CO₂ sensors that were impacting air quality and energy performance. These were corrected alongside the pipework retrofit to ensure the HVAC system operated efficiently and met compliance standards.
Working in a live operational environment, the team coordinated each stage to minimise disruption. The upgraded pipework and VRF air conditioning systems now deliver consistent climate control and optimised airflow throughout the facility.
Energy Efficiency and Smarter Operation
Upgrades to the Building Management System (BMS) allow for precise system control, improving energy use and day-to-day performance. With more accurate CO₂ monitoring and balanced airflow, the system delivers measurable improvements in efficiency, comfort, and sustainability.

Frequently Asked Questions
What makes VRF air conditioning systems a good fit for commercial retrofits?
VRF air conditioning systems are well suited to commercial retrofit projects because they offer flexible zoning, quiet operation, and strong energy efficiency. They allow different areas of a building to be controlled independently, often without major structural changes to the existing layout.
How does PSB Air handle complex pipework retrofits for VRF systems?
Our team starts with a detailed site assessment to understand the existing pipework and system layout. From there, we design a retrofit strategy that improves performance and reliability while keeping downtime low for the client. Correctly designed and installed pipework is essential for VRF systems to operate as intended.
Why are CO₂ sensors important in commercial air conditioning systems?
CO₂ sensors are critical for maintaining healthy indoor air quality in commercial buildings. They help the HVAC system adjust ventilation rates based on occupancy, supporting compliance with standards and improving comfort. In projects like Ausgrid Ourimbah, resolving CO₂ sensor issues ensures the system runs both efficiently and safely.
How do air-cooled VRF systems improve energy efficiency?
Air-cooled VRF systems modulate refrigerant flow in response to real-time demand. This means they only use the energy required to maintain set conditions, rather than running at a constant output. As a result, they can reduce energy consumption while still providing consistent comfort across multiple zones.
What are the benefits of choosing a commercial air conditioning company with retrofit experience?
Retrofit-experienced teams can diagnose legacy issues, integrate new VRF technology, reduce downtime, and protect overall system efficiency. This is especially important in operational facilities where work must happen with minimal disruption.
