Our Process

Working with builders and architects requires clear communication, reliable scheduling, and careful coordination.
Our process ensures HVAC systems integrate smoothly with the overall construction program.

Consultation & Plan Review

We begin by reviewing the architectural drawings and discussing the project requirements with the builder or architect.

During this stage we assess:

  • House layout and ceiling space availability

  • Preferred system type (ducted, multi-split, or concealed systems)

  • Return air locations and diffuser placement

  • Zoning requirements and room usage

  • Builder construction timeline

This early consultation helps avoid design conflicts later during construction.

HVAC System Design

Based on the plans and project requirements, our team designs a system configuration that balances comfort, efficiency, and aesthetics.

This may include:

  • Equipment selection and system sizing

  • Duct layout and diffuser positioning

  • Zoning configuration for different areas of the home

  • Outdoor unit placement

  • Integration with architectural ceiling designs

Our goal is to ensure the system works seamlessly with the home design while maintaining high performance and reliability.

Installation & Builder Coordination

Our in-house installation team coordinates closely with the builder throughout the construction process.

We schedule installation stages to align with the building program, including:

  • Rough-in during framing stage

  • Duct installation and system setup

  • Indoor and outdoor unit installation

  • Electrical coordination where required

We focus on clean workmanship, organised installation, and minimal disruption to other trades on site.

Commissioning & Handover

Once installation is complete, we fully test and commission the system to ensure optimal performance.

This includes:

  • System pressure and airflow checks

  • Zoning configuration and controller setup

  • Temperature calibration

  • System performance testing

We then provide a clear handover to the homeowner, including instructions on system operation and maintenance.
