Oztech vs Mechanical Contractors:
The BMS Difference
Mechanical contractors with in-house BMS teams offer convenience. For performance, system depth, and long-term building outcomes across Sydney and Australia, dedicated BMS expertise delivers results that generalist teams cannot match.
Three Reasons Specialisation Wins
BMS is our entire business. That focus creates a measurable difference in outcomes for building owners, facility managers, and consultants.
Depth of Experience Across Complex Sites
Mechanical contractors encounter BMS only within their own mechanical fitouts. That limits exposure to the challenging scenarios, retrofits, mixed-use sites, and legacy integrations that define real BMS expertise. At Oztech, this complexity is our core business across 100+ active sites nationwide.
Software and Tuning, Not Switchboards
Achieving a NABERS rating improvement or sustained energy savings requires deep knowledge of control logic, algorithm tuning, and dynamic optimisation. Mechanical contractors typically commission a system and move on. Oztech actively tunes each building, drawing on 30+ years of hands-on BMS programming experience.
Custom Logic for Your Specific Building
Default settings do not deliver high performance. We work closely with building managers and consultants to write custom control logic tailored to your site’s exact constraints, occupancy patterns, and energy objectives. No two buildings receive the same programming.

We Do Not Replace Mechanical Contractors. We Work Alongside Them.
At Oztech, we integrate our BMS expertise with the mechanical systems our contractor partners install. That division of expertise, programming and tuning on our side, mechanical plant on theirs, produces outcomes that neither party delivers working alone. It is a model that has worked for over 30 years.
