Choosing Between Multi-Head Split Systems and Ducted A/C

When deciding what sort of air conditioning system to install in your home or business, the two main options are ducted air conditioning and multi-head split systems. We’ll go over how each system operates and the pros and cons, so you can decide which would work best for your property and budget.

Multi-Head Split Air Conditioning Systems

A multi-head air conditioner consists of three main components: a single outdoor unit, several indoor units, and a network of cooling pipes that connect them.

Pros and Cons

A multi-head air conditioner is designed to cool a property within a short period of time. Since systems with multiple indoor units can be installed throughout the property, each room will be cooled at an even temperature, ensuring proper circulation throughout. This can be an excellent option for larger properties or homes that have several rooms that are far apart from one another. 

This system also allows you to control the temperature of different rooms in a building. This means that you can have cooler rooms to sleep in during the summer and warmer rooms to relax in during the winter. It also means you can save energy by only heating or cooling rooms that are in use.

There are some disadvantages to multi-head split systems. They often cost more to buy and install than single split systems, but if you want to cool several rooms in your home at a time, they may be the cheaper option. You also need to have an internal unit in each room where you want cooling. This can create a cosmetic issue or an issue with space usage.

Thankfully, most modern multi-head split systems are designed to be attractive and compact.

Ducted Air Conditioning Systems

Ducted air conditioning is a more traditional system for cooling a house. The unit is placed outdoors, but its pipes run throughout the air space of the house or business and are connected to each room via holes in the wall.

Pros and Cons

The most significant benefit of using a ducted system is its ability to efficiently cool a large area. A ducted system is also good for homes that have larger rooms that are hard to cool. Keep in mind that ducted systems cost more upfront, but they are more cost-effective in the long run.

Another benefit of ducted systems is that they offer the ability to control the temperature of each room. Since you can adjust the temperature of each room separately, you can control the temperature of certain rooms using less energy while leaving other rooms at their optimal temperature.

Redirecting air from the outside through metal tubing into your home can be more expensive and time-intensive than installing a split or multi-head split air conditioning unit. You must first determine whether you have the roof space to accommodate such a unit and the space needed in each room for the vents.

If you want a ducted air conditioning system, you must decide what kind of unit will be most effective. In addition, you need to determine whether the tubing in your ceiling needs to be replaced or if the tubing will get rid of any risks that come with having holes cut into it. 


When deciding which air conditioning system is for you, don’t forget to look into the installation costs and whether your property can accommodate each system. Regardless of the air conditioning system you select, invest in a good quality product to ensure your system can effectively cool your home.
