Fredon’s mechanical services division specializes in the design, installation and maintenance of heating, air conditioning and ventilation (HVAC) systems for commercial and industrial projects. Our performance comes from our multi-disciplined team of professionals including in-house project managers, engineers, drafters, supervisors and technicians. We offer the expertise and resources to undertake projects of any size from conception through to operational handover, service and maintenance, and upgrades or additional works.

Why Fredon HVAC?

Our services integrate to cover the lifecycle of a building.  We have a track record of delivery of many large and complex HVAC construction projects brought in on schedule, within budget employing leading edge HVAC technologies to deliver optimum energy and cost efficiency.  This foundational skill underpins our 24×7 Service and maintenance business, which utilises the latest preventative and on-call methodologies.  Equally our Services and special projects business offers upgrades and ongoing works directly to building owner/managers that leverage the same industry leading resources we bring to our construction work, but with specific expertise relevant to that context.

Service & maintenance

Our Service and maintenance business is engaged in its own right by many clients because of its reputation and national presence.

We also often maintain the buildings for which we have designed and/or constructed the mechanical services, and for these contracts we have developed a transition method to avoid the common disconnection between construction works and handover for maintenance. The design and construction teams introduce our service technicians to the project during the commissioning phase so they have full familiarity with systems. This is particularly critical to ensure that Green Star and NABERS objectives are not compromised.

This practical engagement with design and construction work helps us to maintain and operate not only our work, but better understand other clients’ systems to deliver optimum efficiency and cost effectiveness. We believe it gives Fredon Service and maintenance its edge.  More about Fredon HVAC Service and Maintenance including our preventative and on-call maintenance methodologies…
