Split System vs Ducted Air Conditioning — Which Is Right for Your Wide Bay Home?
If you're thinking about installing air conditioning in your Wide Bay home, the biggest decision you'll face is whether to go with a split system or a ducted setup. Both will keep you cool through our hot, humid summers — but they're very different beasts when it comes to cost, comfort, and how they fit your home.

If you're thinking about installing air conditioning in your Wide Bay home, the biggest decision you'll face is whether to go with a split system or a ducted setup. Both will keep you cool through our hot, humid summers — but they're very different beasts when it comes to cost, comfort, and how they fit your home.
Here's a straightforward comparison from someone who installs both, every week, across the Wide Bay.
Split Systems — The Practical Workhorse
A split system has an indoor wall-mounted unit connected to an outdoor compressor. It cools (or heats) one room — typically a living area or bedroom.
Best for: - Single rooms or open-plan living areas - Homes without ceiling space for ductwork - Budget-conscious installations - Retrofitting older homes without major renovations
Typical cost: $800–$2,500 installed per unit, depending on size and brand.
Pros: - Lower upfront cost — install only the rooms you use - Zoned by design — everyone sets their own temperature - Easy to add later — no ductwork needed - More energy efficient when cooling a single room
Cons: - Visible wall unit in every room (not everyone loves the look) - Multiple outdoor units if you want multi-room cooling - No central temperature control
A good rule of thumb: if you mainly want to cool your living room and a couple of bedrooms, and you don't mind the units on the wall, split systems offer the best value.
Ducted Air Conditioning — Whole-Home Comfort
Ducted air conditioning uses a central unit (usually in the roof space) connected to outlets in each room via ducts. One controller manages the entire home.
Best for: - Whole-home cooling and heating - Larger homes (four bedrooms and up) - New builds or major renovations - Homes where aesthetics matter — only grilles show in the ceiling
Typical cost: $8,000–$18,000 installed, depending on home size and system capacity.
Pros: - Invisible — discreet ceiling grilles, no wall units - Consistent temperature throughout the home - Can be zoned to cool selected areas (saves power) - Adds resale value - Single outdoor unit, neat installation
Cons: - Higher upfront cost - Requires roof space for ducting - Less efficient if you only need to cool one room - More complex installation — not ideal for quick retrofits
Energy Efficiency and Running Costs
Here's what we see on the ground in the Wide Bay:
- Split systems win on efficiency when you're cooling one or two rooms. A modern inverter split system uses very little power once the room reaches temperature.
- Ducted systems with zoning let you block off unused areas. A well-zoned ducted system can be surprisingly economical, but running the whole house all day will cost more.
- Ceiling insulation matters more than most people realise. A poorly insulated home will cost a fortune to cool regardless of which system you pick.
Both options are available in high-efficiency inverter models with good energy star ratings. It's worth paying extra for a higher rating — the savings in running costs add up fast over a Wide Bay summer.
What Wide Bay Homeowners Typically Choose
In our experience, here's how it usually shakes out:
- Three-bedroom homes and under: Split systems. Most homes in this range don't have the roof space for ducted, and the cost difference is hard to justify.
- Four-bedroom-plus homes or new builds: More people go ducted, especially if they're building new and can plan for it from the start.
- Rental properties: Landlords in the Wide Bay tend to favour split systems for their lower upfront cost and easier maintenance.
Our Recommendation
If you're building new or doing a major renovation, ducted air conditioning is worth the investment — it adds comfort, value, and a clean look. If you're retrofitting an existing home, split systems are typically the smarter choice.
