Simple Cost Formula (Sydney)
Total price ≈ (equipment) + (ductwork & zoning) + (labour) + (electrical) + (access complexity)

Design & Build Quality
From the homeowner’s perspective, ducted air conditioning is about what you don’t see. Ceiling vents are discreet, ductwork is hidden, and modern controllers integrate cleanly into living spaces.
From an installer’s perspective, quality comes down to:
- Correct duct sizing (airflow balance)
- Insulation rating of ducts
- Secure mounting & vibration control
- Weather-protected outdoor unit placement
Poor duct design is the #1 reason Sydney systems underperform. We see this weekly when fixing systems via our
ducted air conditioning repair services.
