Ducted AC vs split AC cost
Choosing between split AC and ducted AC is not just a comfort decision. It is also a budget, coordination and maintenance decision. This page shows the cost gap between the two strategies and explains why some projects stay with split, some go mixed, and some justify full ducted systems.
Budget snapshot

Planning range Split: IDR 1.0M-3.2M vs Ducted: IDR 2.1M-5.8M / m² cooled area
Best for Comparing split AC and ducted AC cost, coordination burden and long-term maintenance risk before selecting a cooling strategy.
Example planning scenarios
| Scenario | Area / basis | Specification | Planning range | Unit range | Important note |
|---|---|---|---|---|---|
| Practical split baseline | 120-260 m² cooled area | Room-by-room split units, simple controls and lower ceiling coordination burden. | IDR 120M-832M | IDR 1.0M-3.2M / m² | Best for standard homes and projects where simplicity matters more than hidden distribution. |
| Premium ducted baseline | 120-260 m² cooled area | Concealed ducts, return air, diffusers, insulation and balancing. | IDR 252M-1.51B | IDR 2.1M-5.8M / m² | Best when visual integration, acoustics and premium comfort justify the extra system burden. |
How to use this guide
Start with split AC unless the architecture and comfort targets clearly justify ducted distribution.
Use a mixed strategy when premium common spaces matter more than hidden cooling in every room.
Scope assumptions
Usually excluded or priced separately
- Balanced fresh-air systems and specialist building controls unless separately budgeted.
- Architectural changes caused by late cooling strategy decisions.
What changes the number
- Ducted systems cost more because they add space, ductwork, balancing and service access complexity.
- Split AC carries lower capital cost but can create facade clutter and more outdoor units.
- Mixed systems are often the most financially efficient premium strategy.

FAQ
Which system is cheaper to install?
Split AC is usually cheaper to install because it needs less ceiling space, less ductwork and less balancing effort.
Which system is easier to maintain?
That depends on access design. Split units are simpler individually, while ducted systems can be maintainable if return air, filter access and service hatches are properly planned.
