Case Study: Duplex Bulkhead Air Conditioning Installation

5 Head Multi Split System Bulkhead Installation

This is a bulkhead air conditioning installation in a residential duplex using a multi head split system setup that includes the following components:

  • 15.5 kW Mitsubishi Electric five-port multi outdoor unit positioned on the ground down the side access;
  • 7.1 kW Mitsubishi Electric bulkhead indoor unit for the downstairs kitchen living room;
  • 5 kW Mitsubishi Electric bulkhead indoor unit for the Master bedroom; and
  • Three x 3.5 kW Mitsubishi Electric bulkhead indoor unit for the three smaller bedrooms.

This is how the multi installation appears on the floor plan:

Residential Bulkhead Installation and Multi Split System Installation


This multi-split system bulkhead air conditioning installation was completed on two duplexes with identical floor plans and air conditioning layouts.

A 5kW split system bulkhead air conditioner was installed in the Master Bedroom above the door, with a wall grill and a return air grill hidden in the robe. We lowered the ceiling inside the walk-in-robe to accommodate the air conditioner.

For the other bedrooms — two, three, and four — we installed a 3.5kW bulkhead air conditioning unit. Bedrooms two and four had bigger wall grilles, eliminating the need for a separate return air grill, but bedroom three’s small wall grill required us to place a return air grill on the side of the built-in wardrobe.

Lastly, we placed a 7.1kW bulkhead aircon unit above the Kitchen cabinets to service the Kitchen-Living room; this unit had a large wall grill that also removed the need for a return air grill.

Additionally, each bulkhead was fitted with a wall controller and a WiFi adaptor, which allowed users to control the air conditioning in each room of their house through their smartphone and ensure everyone’s comfort.

    Really glad I chose Ready for my ducted aircon install. It wasn’t a straightforward job for them but they were professional and communicative and we love our new system. I’ll be recommending these guys to everyone!

    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.
