What Is A Multi Head Split System Air Conditioner?

Posted in:
Multi Head Installation Sydney Apartment Head Split System Installation Sydney - Apartment Air Conditioning Layout with Internal Trunking

A Versatile Space Saving Solution

A multi head split system air conditioner uses multiple indoor units connected to a single outdoor unit via refrigerant lines for cooling multiple rooms at once.

Some multi-head split systems can have up to six head units of various types, such as wall-mounted, floor-standing, bulkhead, ceiling-concealed ducted units, ceiling cassettes, or ceiling-suspended units. This number is dependent on the size of the building, how many rooms need to be cooled, and the power required.

These wide range of head unit options offer end-users versatility, as different combinations of head units can be used for any situation.

This Northern Beaches multi head split-system installation includes:

5.2 kW Mitsubishi Electric two-port multi outdoor unit; as well as
Two 2.5 kW Mitsubishi Electric wall mounted indoor head units for each bedroom.
We installed both indoor units in the bedrooms, back-to-back with the outdoor unit and ran a 20 Amp power circuit from the nearby switchboard through the brick cavity. This allowed the services to go into a T-shaped Colorbond trunking, creating an efficient system with minimal exterior clutter.

Multi Split Air Conditioner Cost

Multi Head Split System Installation Comparison

Generally speaking, a multi head split system air conditioning installation is more expensive than a split system and a ducted installation tend to be the most costly.

The cost of the unit increases with size and different head units can have different installation costs; for instance, bulkheads are more expensive than wall-mounted split systems. Furthermore, the complexity of the installation will also affect the cost. The more head units you require the greater the cost. Finally, additional features, such as Wi-Fi connectivity, and other options added to the system will also incur a cost.

When choosing an air conditioner for your home, it’s best to consider the layout of your home, any restrictions it has and what you’re truly trying to achieve. We will recommend the best solution for your home and including pricing options that fit your budget so that you can make the right choice.
