New builds, existing buildings & full modernizations
Whether it's a greenfield site still on the plans or a 40-year-old building running on tired R22 plant, we scope, supply and install the right system for the space — with minimal disruption to your tenants and operations.
Ground-Up New Builds
Working from plans alongside builders and services consultants to install brand new systems into new construction — pipework, ducting, plant and commissioning all staged to the build program.
New Installs in Existing Buildings
Adding cooling to a tenancy, fit-out or extension that was never air-conditioned — retrofitted line-sets, ceiling penetrations and discreet condenser placement without trashing the building.
Retrofitting Old Buildings to New Systems
Replacing obsolete or failed plant with modern, energy-efficient equipment — reusing existing risers and ceiling space where possible, and decommissioning old refrigerant responsibly.
Plant Modernization & Upgrades
Full system modernization — swapping legacy chillers, AHUs and controls for current inverter and VRF technology to cut running costs and meet modern compliance.
Installed right the first time
A clear, no-surprises installation process so your building managers and tenants know exactly what to expect.
1. Site Measure & Scope
We inspect the site, assess loads, access and structural requirements, then give you a clear scope and transparent quote.
2. Compliant Trade Work
QBCC & ARCtick licensed installers handle penetrations, mounting, pipework and drainage — neat, tidy and to spec.
3. Commissioning
Full refrigerant handling, vacuum evacuation, electrical testing and controls set-up with documented start-up.
4. Handover & Warranty
Warranty documentation, asset registers for building managers and a maintenance plan to keep it running.
