How We Transformed Comfort in a Sanctuary Point Family Home With a Modern Ducted Replacement
Introduction
Location: Sanctuary Point
Service: Ducted System Replacement
Client Type: Large Family Home
Outcome: Quiet operation, stronger airflow, lower running costs, better zoning
A large family home in Sanctuary Point needed a complete ducted system replacement after their old 16-year-old unit began failing during summer heatwaves.
With multiple teenagers, bedrooms spread across two ends of the home, and high peak usage, they needed a modern, zoned solution.
Summary of Results
- New 16kW Daikin ducted system installed
- Running costs reduced by 33%
- Quiet operation for night-time comfort
- Zoning allowed for morning/evening control
- Improved airflow in all bedrooms
Client Background
The home had:
- An ageing ducted system
- Weak airflow to back bedrooms
- Loud rattling noises during operation
- High electricity bills (especially summer)

They needed a future-proof solution.
The Challenge
- Large, spread-out floor plan
- Uneven ducting from previous installers
- Bedrooms getting minimal airflow
- Outdoor unit exposed to harsh western sun
- High family usage → high energy consumption
