Pay depends on the work the engineer owns. An engineer producing calculations under supervision has a different remit from someone leading mechanical design, coordinating other trades and resolving technical issues through installation and commissioning. These published Sydney and NSW examples give you a starting point for comparing similar roles.
Design responsibility. Check whether the engineer will produce calculations and select equipment under review, own a package independently or review the work of other engineers.
Project scope. A commercial fit-out, a central plant replacement and a data centre cooling project call for different experience. Compare the systems involved, the stage of delivery and how much coordination the engineer will own.
Site and leadership commitments. Ask how often the engineer will attend site, whether they’ll support testing or handover outside normal hours, and whether they’ll manage staff or take responsibility for project deadlines.
If the vacancy is primarily for hands-on servicing, breakdown response or refrigeration repairs, benchmark it against the relevant technician role. Explore our HVAC & Refrigeration Recruitment discipline for the different roles we cover.
Confirm whether the quoted figure is base salary plus superannuation or a total package. Ask how the employer handles vehicle or travel allowances, overtime and any commissioning work outside normal hours.
If you’re hiring, speak with our team about the systems, project stage and level of responsibility. If you’re looking for your next role, browse current vacancies or submit your CV with examples of the projects and systems you’ve worked on.
The graduate reference comes from the Hays Engineering Salary Guide FY26/27, which publishes a typical Sydney and NSW figure for graduate building services design, excluding superannuation.
The project and senior figures are published recruitment examples: the range stated in the body of the Connexus HVAC Project Engineer listing and the advertised range in the Design & Build Senior Mechanical Engineer (HVAC) listing, published in October 2026. Both describe pay with superannuation on top.
Figures are in Australian dollars per year. The two recruitment listings illustrate what specific Sydney briefs can pay; they do not establish national salary ranges or show what candidates ultimately accepted.
