Where Can Multi Head Split Systems Be Installed?

Multi Head Split System Locations

Multi-head split systems can be installed in any residential or commercial building that has the necessary space, such as houses, duplexes, townhouses, apartments, and offices.

The outdoor condensing unit should be placed in a well-ventilated area, away from direct sunlight and other sources of heat where possible. The indoor units should be installed in the rooms that need cooling. It’s important to make sure that the system is the correct size for the space it’s meant to cool.

Apartment buildings are a common place where we install multi-head split systems, since ducted installations aren’t possible. They require a ceiling void, which most apartments don’t have. A single split system can only cool one room at a time, or you can use internal trunking to position it across from open doorways to get airflow into bedrooms. However, this doesn’t look as nice.

By choosing to install a multi-head split system, it lets you cool multiple rooms at once, with a cleaner look.

Multi Head Split System Installation Examples

2 Head Multi Split System Installation – 2 Bedroom Apartment

When targeting several rooms in an apartment, the best solution is to install a multi-split system. However, there are some limitations to consider such as the interconnecting piping between the indoor and outdoor units, and the positioning of the rooms. To achieve an ideal finish, direct services should be run out through external walls rather than using internal trunking.

Here are some examples of different positioning options, along with their respective benefits and drawbacks. The floor plans demonstrate two choices for the same apartment.

Multi Head Split System Option 2

We recommend Option 1 as the head unit placement for its attractive finish and no need for internal trunking. However, the head unit in the master bedroom isn’t in the middle of the wall. Despite this, it still works well for heating and cooling the room.

Option 2 moves the master bedroom head unit to the centre of the wall, with internal trunking. This also allows the living room head unit to be repositioned, since its services use the same trunking.

Installation of a head unit in bedroom two may be possible, but the difficulty and expense of running the services might not make it worth the effort. An alternative solution is to install a separate split system to target the second bedroom.

3 Head Multi Split System Installation Bondi – 3 Bedroom Apartment

This multi head split system installation in a Bondi apartment included the following components:

  • 7.1kW Mitsubishi Electric 3 Port Multi Outdoor Unit (MXZ-4F71VGD-A1) positioned on the balcony;
  • 5kW Wall Mounted Indoor Head Unit (MSZ-EF50VGD-A1) for the living room;
  • 2.5kW Wall Mounted Indoor Head Unit (MSZ-EF25VGD-A1) for the master bedroom; and
  • 2.5kW Wall Mounted Indoor Head Unit (MSZ-EF25VGD-A1) for the second bedroom.

This is what the multi-installation looks like on the floor plan:

The layout of the Bondi apartment enabled us to install three multi head units with minimal internal trunking.

In the living room, the head unit was positioned side-to-back with the outdoor unit above the TV. Bedroom two was placed back-to-back with the living room, with both their services sharing the same internal trunking. Lastly, the master bedroom unit was situated in the corner of the room and its services ran outside the building.

This apartment’s floor plan is an example that compliments a multi head split-system installation. Here are photos of the completed multi head split system installation.

The challenge of this multi-head split installation was to find a solution for the head units in the lounge and bedroom three, since the owner only wanted to use the master balcony.

To resolve this, we found compromise by placing the lounge head unit above the master bedroom doorway and running services into bedroom two. Unfortunately, this meant that the internal trunking became visible in bedroom two.

To address the second issue in bedroom three, we used a water pump to push the condensation waste water created by the air conditioner outside. This also allowed us to install the internal trunking in the corner of the bedroom two ceiling, making it hardly noticeable.

This complex installation exemplifies the challenges we faced and the compromises necessary to ensure air conditioning reached every room.

    Very happy with the great work from the whole team at Ready Electrical! My split system was in desperate need of a clean and Greg was able to send a team out to my place the very next day. The guys did a fantastic job making my aircon look and function as if it was brand new, and they were also so thorough at keeping the space clean with lots of drop sheets / tarps. Thank you for the great work...

    Greg & all his team provided us with an excellent service to install a new ducted aircon system a couple of weeks ago. There was great communication throughout the quoting process and the install was seamless with the team leaving the house very tidy. We needed a slight tweak to the system after using it for a few days and it was sorted out straight away with great efficiency. Highly recommended.

    I could not fault Ready Electrical and Air Conditioning. I have neglected my split system for over three years and yesterday it started leaking. Found Ready on Google this morning and from the first phone call, the job was completed in around three hours. Technician was friendly, clean, and he took the time to show me how to clean it every three months - not years. I would use them again.
