About us
Let’s work together
As one of Brisbane’s trusted mechanical services contractors, we help our clients turn their visions into reality. That means thinking outside the square and creating innovative ways to provide simple and effective engineering solutions that support world class projects.
We pride ourselves on delivering a customer focused, solutions-based service where on-time delivery is always front of mind. Our solutions are also tailored to meet the needs of each specific project.
At Navaska, we specialise in electrical and mechanical services including commercial air conditioning and commercial and industrial refrigeration solutions. We provide high-end design, installation and support services to construction, commercial and industrial customers across South East and Central Queensland.
The business has grown significantly over the past 25 years, with our Managing Director Ross McLennan launching the company in 1997 as a small family run business. Today Navaska is a multi-layer, multi-division, national mechanical services contractor with over 70 highly-specialised staff. While our size has changed, our focus on small business values such as honesty, integrity and quality hasn’t. We are reliable, dependable, cost effective and proactive. We treat our clients like family and value the importance of building trusted, long-term relationships. Our clients come first and we have a strong focus on understanding their needs, requirements and desired outcomes for every project from the outset.
