Walliston Primary School – HVAC Upgrade & Installation

Walliston Primary School required a full HVAC upgrade as part of a broader roof replacement program – replacing an ineffective evaporative air conditioning system with 15 reverse cycle wall split systems and 9 fresh air fans. All works were coordinated with the principal builder, Safeway Building, and delivered within the Christmas school holiday window.

The Problem

Walliston Primary School’s existing evaporative air conditioning system was failing to provide adequate cooling during peak summer conditions. A full HVAC system replacement was required as part of the school’s broader roof replacement programme.

The existing evaporative air-conditioning system was ineffective during peak summer conditions

The school is located within a bushfire-prone area, requiring evaporative units to meet BAC (Bushfire Attack Category) approval standards

Classrooms lacked heating during winter months, creating comfort and compliance concerns

All works had to be completed within a tight Christmas school holiday shutdown period

The Solution

Complete Refrigeration & Air coordinated directly with Safeway Building and all associated trades to ensure works were sequenced correctly across the holiday window without trade interactions causing damage to newly installed equipment.

Decommissioning and removal of the existing evaporative air conditioning system

Supply and installation of 15 BAC-compliant reverse cycle wall split systems across classrooms

Supply and installation of 9 fresh air fans to provide compliant ventilation across the school

Pre-ordering of materials to maintain installation flow throughout the project

Full trade coordination and clear communication with cranage, plumbing and electrical trades

The Outcome

All works were completed within the allocated school holiday timeframe despite multiple trades operating onsite simultaneously. The result was a safe, efficient installation delivered under tight constraints with strong collaboration across trades. Completed with a satisfied customer and safe team. 

Project delivered on schedule

No defects recorded by the builder
