What is a Multi-Split
Air Conditioning System?

A Multi-split system air conditioner is the most energy efficient way to bring the comfort of conditioned air to your family home, office complex or multi-level building.

The Multi-split system, comprising one compressor and condenser coil, housed in a robust cabinet positioned outside, can connect up to five indoor units individually set at different temperatures for varying comfort levels.

The compressor supplies sufficient refrigerant to each coil to achieve a maximum cooling rate at each indoor unit then automatically reduces refrigerant flow as the set temperature in each room is achieved then maintains it at that level.

The “heart” of the Multi-split system is the inverter type compressor. This type of compressor automatically regulates its workload according to the needs of each individual unit and the selected room temperature requiring a lower energy demand and less power consumption once the required temperature is reached and maintained.

Why is Multi-Split Air Conditioning important?

A Multi-split system air conditioner is much quieter and responds automatically to applied heat loads such as increased occupant numbers, influx of outside air through opening doors or changing solar characteristics as the sun changes direction.

More consistent comfort levels for all occupants within a given living space.
Ability to independently vary comfort levels in different zones
The inverter type compressor, the critical component in the system, has a high COP (Co-efficient of Operating Performance) enabling maximum cooling until the set temperature in each room is reached, then automatically maintains that temperature thereby, reducing power demand.

How can we help find the
best Multi-Split Air Conditioning System for you?

The most suitable Multi-split system for your use depends on a number of factors including the building function, internal volume, number of doors and windows and the number of anticipated occupants.

We will visit your home, site or work with your architectural team to determine a system best suited to your individual needs. Whether that is for a family residence, or multi‑function building.

At Alliance Climate Control, we can bring together the best Multi-split products available from a wide range of options, able to satisfy any operating characteristic that might exist.

From timed operating sequences that activate the system before you arrive home or sleep functions to shut the system down after retiring each night. Even Wifi activated applications are available to control your Multi-split system with a Smart phone application whilst you are away from home.

We will also be there with you during the installation and commissioning process to make sure the selected unit will deliver the requirements ensuring you are absolutely satisfied before final acceptance.

We will also be there to support operation of your system to make sure it operates correctly day after day, year after year.

Ivan, Mosa & Luke and electrician Aaron, Ken & Harry were very professional and courteous while they installed my ducted system in my upstairs bedrooms on a very hot day (34 Degrees).

Totally impressed by Alliance. The communication was very good and the technician (Kody) was personable, professional and most helpful. Kody presented options to resolve our ac problem and was honest and objective with the choices before us. The repair was completed on the initial visit! Particularly good value. A very happy customer and we’ll definitely call them if we have any future ac needs.

Re: Dais, Sayed & Christian
Hello,
I have been meaning to send this email for quite some time, but due to poor health, and lots of other excuses, I simply haven't gotten around to it.

I wanted to provide feedback for the above job number, as the boys really did work their arses off! It was a complicated job (which even I could see as a layman), and yet nothing was off-limits. They really did everything to accommodate the job, and my individual requests. As an individual, I am very particular and hold very high standards, and yet, they did not blink and eyelid.

I would also like to mention that all three of them were a delight to have in my home. It goes without saying, that they are a credit to your company, and it was an absolute pleasure working with them.
Kind regards
Lisa

Alliance installed another Daikin Zena split system in our house today and did a brilliant job as per usual. Ahmad & Maisam were the install team and they were fantastic…explained things perfectly and did an absolutely first rate job. Very happy.

Charles and Aden from Alliance Climate Control have demonstrated exceptional work ethic and professionalism.
From a courtesy call, to his arrival, Charles provided a clear explanation of the procedure to identify the issue and rectify the electrical problem. I was particularly impressed by their continued diligence in locating the problem.
I have hesitation in recommending Charles and Aden and of course your company,

We have high regard for the whole interaction that we had with Alliance Climate Control personnel. Aysa helped us to make our informed choice with the ac system that the technicians installed. Aysa is very friendly, courteous and knowledgeable. The technicians, Yunus, Can and Carlos, were very punctual and called us in advance to let us know of the time they will be coming. Their advice, workmanship and attention to detail were amazing. We take this opportunity to thank Yunus, Carlos, Can and Aysa and the supporting staff from the office, Luke and Cara. 👍👍👍
