HVAC Maintenance

Maintaining excellence,
building for the future.

Responsiveness. Quality. Efficiency.

They are cornerstones of the professional service delivered by our expert HVAC Maintenance teams.

A building’s mechanical systems only perform efficiently if maintained consistently and expertly. We offer a full suite of maintenance services, tending to your assets with a mix of care, skill and decades of experience.  

As a result, your building will perform to its full potential — meaning cost savings, higher energy efficiency and environmental ratings and greater tenant satisfaction overall. 

Even before your new building is occupied, our engineers and technicians will work with you to develop a maintenance plan which is tailored to your needs and ensures the long-term value of your asset is managed, and its performance is optimised and extended.

Our HVAC Maintenance Capabilities

General Mechanical and Fire Safety System Maintenance

You’ve invested a lot of time and money into your mechanical system, and you want that value to last. Our team of trained technical experts will work with you to develop a customised and proactive maintenance program.

These programs meet the needs of your individual facility to keep your critical assets and investments running smoothly. We are committed to providing you with a first-class service experience.

Cooling Tower Risk Assessment and Maintenance

Neglecting cooling tower maintenance can be costly and high-risk. Our skilled technicians can perform the routine checks and risk assessments you need to get the best out of your equipment and to provide a clean and safe work environment.


From inspecting and studying, cleaning and flushing, to servicing your mechanical equipment, we can identify and address issues early to ensure your system is performing at its best.

Chiller and Heat Pumps

Our highly trained and experienced technicians can perform routine preventative maintenance checks on your chiller and heat pumps. This involves inspecting, verifying, diagnosing and repairing issues to optimise the performance of your mechanical system and reduce the risk of unexpected, and potentially costly, large-scale repairs and downtime.

Energy Management

Energy management of your mechanical system is of primary importance to the performance of your building. Our expert team can assess and evaluate the operation of your system.

We share new ideas and technologies to make your equipment perform better, and provide monitoring and reporting solutions to maximise energy efficiency and reduce operating costs without impacting user comfort.

NABERS Assessments

Demand for greener buildings that consider their environmental impact are on the rise with procurement teams, purchasers, and tenants. We can work with you to conduct NABERS assessments.

We help you to accurately measure and understand the current environmental performance of your building, as well as to identify areas for future improvements and cost savings.

HEPA Filtration and Fume Cupboards

We are a NATA accredited business capable of providing on-site mechanical testing and certification services to support organisations to meet their obligations for controlled environments, and ensure they are operating safely and efficiently.

Our services include NATA testing and compliance, HEPA filter testing, supply and replacement, and compliance testing and validation of fume cupboards in accordance with Australian Standards.

Total focus on your building 

and its performance. 

From concept design, installation and commissioning to the ongoing HVAC maintenance of your facility, we have the in-house expertise to keep your critical assets running smoothly. 

Water Treatment

HVAC systems that utilise water are prone to corrosion, scale build-up and organic material growth that if left untreated, can result in poor performance and costly breakdowns.

Routine maintenance by our experienced team will reduce liability and safety concerns, maintain equipment and warranties, identify concerns before they become expensive problems and increase energy savings. 

Building Management Systems (BMS)

A BMS is fundamental to the successful operation and energy efficiency of your building. Whether installing a management system as part of a new construction or as an upgrade to an existing building or system, we have the expertise and technology to guide you through the process.

Our skilled technicians support the integration and service of building management systems, controls engineering and building automation in commercial buildings with the goal of enabling maximum system efficiency and reducing energy costs.
