Who Catalyst Air group is
Catalyst Air Group brings together specialist HVAC and refrigeration businesses operating across Queensland and northern New South Wales.
We built Catalyst around a simple idea: customers should be able to access genuine specialist capability at the level they need, in the location they need it, without being forced into the one-size-fits-all model of a large national provider.
Our businesses remain close to their customers and markets. Catalyst provides the group structure, standards, technical resources, procurement strength, systems and accountability that allow those businesses to work together and perform at a higher level.
The Catalyst air group model
Catalyst Air Group is built as one company, with specialist capability working together under shared standards, resources and leadership.

Each operating business brings its own market knowledge, people and specialist strengths. Catalyst Air Group connects them through a common group platform.
