  • Delivering sustainable solutions to prolong service life of your air-conditioning and HVAC system and minimise ongoing maintenance costs.

  • Professionally designed HVAC systems make people more comfortable & increase their productivity
  • You can have Confidence in our National Quality Assurance Program
You can take advantage of our own in-house mechanical engineers to design a energy efficient and sustainable system for you:
  • Using PSG in-house mechanical engineers means you can reduce overall engineering and commissioning time = cost savings for you
  • Together we can identify the most cost effective & efficient air-conditioning & HVAC system for your application and budget.  This means selecting the right sized systems so they work as they should; more reliable equipment so it works when you need it; and you do not need to spend any more than you should for a quality air conditioning and HVAC solution
  • PSG Engineers are on hand to advise technicians, installers and service mechanics.  They are just a phone call away for timely advice any time you need it.  This means less down time, the likely elimination of error and therefore reduced costs to you.


PSG Facility Services are Master Plumbers who design, install and service ac air-conditioning systems and mechanical services to Australian Standards in Sydney, Melbourne, Perth and throughout mainland China. All designs are prepared by qualified mechanical services engineers.

PSG provides design to completion solutions through our strategic partnerships with industry leading consultants and technology providers.  These partnerships allow PSG to deliver streamlined projects from beginning to end, delivering services and expertise to Australian Standards.

The Principal Consultant of PSG Facility Services has more than 25 years experience designing, installing and maintaining air-conditioning systems and mechanical services.  He is often called upon by clients, including local government authorities to identify and design rectification solutions for poorly designed or installed systems (he cleans up the mess made by others!).  

To reduce service call-outs, minimise maintenance and improve the performance and life span of air-conditioning systems, it is not only essential that the design be properly engineered but it is equally important that the system is installed correctly.  You can trust PSG.

Projects designed, installed and serviced by our Principal Consultant include the new administrative offices at Toyota (Yanmar VRV System), shopping centres, hospitals, schools, high-rise buildings such as  hotels, restaurants and night clubs.

Preventative Maintenance of Air-conditioning & HVAC Equipment

Preventative maintenance reduces the likelihood of breakdowns and allows for scheduled repair and replacement while minimising the inconvenience to building occupants.


You can contact PSG Facility Services on 1300 880 992 24/7 for an immediate response.  

System Upgrades

We can help you design, plan, construct and install your HVAC and mechanical services systems.  When replacing HVAC systems, consider high-efficiency units. Replacing air conditioners that are more than 10 years old can save 20-40% of your climate related energy costs annually, and reduce your carbon emissions.  New inverter technology can save up to 30 per cent of energy consumption, compared to conventional air conditioners. Fixed speed compressors will run at full capacity and will stop and start automatically to maintain the desired temperature, whereas an inverter unit will reach the desired temperature quicker and adjust its capacity to maintain a consistent temperature.

  • Improved commercial outcomes
