Ducted vs split system air conditioning: a Shoalhaven homeowners' guide

Choosing the right air conditioning system is one of the most important decisions you'll make to stay cool during a Shoalhaven summer. If you're building, renovating or upgrading your home in Nowra or surrounds, you've likely asked: should I go ducted or split system? Both have advantages — let's break down the difference.

What is a split system?

A split system is a single unit that heats or cools one room or a specific area of your home. It's cost-effective and ideal if you only need to condition bedrooms or living areas.

Best for:

• Smaller homes or townhouses in Nowra
• Rentals or homes under 120 m²
• Zoned cooling (e.g. bedrooms only)

What is ducted air conditioning?

Ducted air conditioning is a whole-home system with vents in each room. It's quieter, more powerful, and cools your entire house evenly — great for beachfront homes, family houses and multi-storey properties across the South Coast.

Best for:

• Larger homes in places like Berry, Cambewarra or Kangaroo Valley
• Families who want year-round climate control
• New builds or major renovations

Choosing the right system comes down to:

	Split System	Ducted System
Upfront cost	Lower	Higher
Whole-home control	No	Yes
Noise	Slight	Minimal
Aesthetics	Visible unit	Hidden in roof
Resale value	Moderate	High
