🌬️ Split vs Multi-Split Systems: Pros and Cons

Choosing the right aircon system for your home can be confusing, especially when deciding between a single split and a multi-split system. Both cool effectively, but they are designed for different home layouts, budgets, and usage patterns in Singapore.

Here is a simple breakdown to help homeowners understand which option suits their needs better.

What Is a Split System?

A single split system has:

• 1 indoor unit

• 1 outdoor condenser unit

It cools one room independently.

✔️ Pros

1. Lower upfront cost: Cheaper installation and equipment cost.

2. Independent temperature control: Each unit runs separately.

3. Cheaper maintenance: Servicing is straightforward and replacement parts are cheaper.

4. Quiet operation: Noisy components are outside, keeping your room peaceful.

✖️ Cons

1. Needs space for multiple outdoor units: If you need aircon in several rooms, every room requires its own condenser.

2. Higher total electricity usage for many rooms: Each unit operates independently, which may use more power in larger homes.

What Is a Multi-Split System?

A multi-split system has:

• 2 to 5 indoor units

• Connected to ONE outdoor condenser

It cools multiple rooms using a single outdoor unit.

✔️ Pros

1. Great for HDBs and condos with limited outdoor ledge space: Only one condenser is needed.

2. Cleaner, neater exterior appearance: Fewer outdoor units.

3. Energy efficient when used in several rooms: One shared compressor can be more efficient than multiple separate units.

✖️ Cons

1. Higher upfront cost: More complex installation.

2. If the condenser fails, all rooms are affected: A breakdown affects the entire home.

3. Indoor units depend on each other: If system capacity is exceeded, cooling may become weaker.

4. Servicing can be more complex: Leak checks and repairs take longer on multi-split systems.

Which Should You Choose?

Choose Split System if:

✔ You only need cooling in 1–2 rooms

✔ You want lower installation cost

✔ You prefer full independence for each room

✔ Your outdoor space can fit multiple condensers

Choose Multi-Split System if:

✔ You have limited outdoor ledge space

✔ You want a neat, consolidated setup

✔ You plan to cool 3–5 rooms regularly

✔ You prefer energy efficiency for whole-home cooling
