What Is A Multi Head Split System Air Conditioner?

Posted in:
Multi Head Split Air Conditioner

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 Head 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.

We had Ready install our ducted and split system at our home recently and couldn't be happier with the outcome. The team was exceptional from start to finish, and really took the time to go through absolutely everything with me from the first meeting to go through options, through to the install itself. Highly recommend

Thanks Greg & Team. Trent & Adam did a great job with the electrics. Lineu, Renzo & their team spend one & a half days installing- climbing through the roof cavity, always checking in with me as the job progressed to ensure I was happy with the work. End result was exactly what I had arranged with Greg. All up happy to recommend this business.
