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.

I’ve had Yunus and his team at my house twice to install air conditioning. I highly recommend their attention to detail, quality and cleaning up, and usefully explaining what they are doing along the way.
Nigel C.
Cristian, Louis and Shaby turned up on time and installed our air conditioner efficiently without issue. Upon completion our home was left clean and tidy.
Thanks for your help

Alliance went above and beyond our expectations, definitely ensuring that we were totally happy with the installation. They are happy to revisit if there are any concerns and will always find a solution to any problem you may have. Highly recommend their services.

Jason and Nick completed a full service of our ageing aircon. Very impressed with their professionalism and attention to detail. I am happy to highly recommend them. They are both outstanding representatives of Alliance, delivering an unbeatable customer experience.
David S.
Blown away by Shazim and Brandon, who were very helpful in trying to fix a problem with my air conditioning which had eluded a number of technicians from other companies over the previous years. Wonderful work, place left clean, helpful and polite service.
Gail J.
Comprehensive efficient service. Problem solved then provided solutions.
Ace G.
I recently had a new air conditioner installed by the team from Alliance Climate Control, led by Vy and supported by Luang, Jamie, Harry, Peter, and Kaj. From start to finish, the service was absolutely first class. The team was professional, efficient, and went above and beyond to ensure everything ran smoothly.

Thank you for delivering such an outstanding customer experience. I wouldn’t hesitate to use Alliance Climate Control again and highly recommend them to anyone seeking reliable and high-quality air conditioning services.

I usually sizzle with hate 'n anger if I'm paying a trillion dollars. But these lads were nuthin short of top shelf, the whole way - utterly professional, thoughtful, polite... and decent 'n honest - a word i do not use lightly. But everything is easier when yve got a shit ton of air con. Cheers
Fergus B.
Needed to either fix or replace our Daikin split air con, we inherited it when we moved in.
Gabriel came for a visit, checked the condition of everything and then explained the issues and potential solutions. He then provided clear options with a formal quote.
Agreed for the replacement with a new system, seamless process.
Ivan and his team then installed it over 1.5 days, great experience, they are super professional and also helped out with a cosmetic issue due to the age of our house (1880s...)
It's been a few weeks since the install and we are very happy with the system and very satisfied with the sales and service teams we engaged with at Alliance Climate Control.
Would definitely recommend!
Dan M
Great team! Vy was attentive, responsive, and creative with both the cabling and aircon zoning solutions. The team took full ownership of the task, handled all the small side jobs without hesitation, and delivered an excellent ducted air conditioning installation. Thank you!
Christopher C.
I engaged alliance to service my two ducted air conditioner systems. Galvis spent a few hours replacing all my filters , cleaning my machines , getting rid of the rust on the machine housing and spraying anti corrosives on the coils . He paid attention to fine details and explained everything he had done to me before leaving. Alliance is not the cheapest but the job they do is of the highest quality.
Anita M.
Andres and Ivan completed a very efficient and clean replacement of my underfloor heating, great service.
Sascha C.
Alliance were extremely professional in dealing with our large complex gas system. We live in an old house with a Braemar gas heating system that is not straightforward. When it stopped pumping hot air I asked for technicians to come out who were experienced and knowledgeable and could diagnose and deal with a problem efficiently. Andre arrived and successfully diagnosed a problem with the temperature sensors damaged by water inside a duct,, and then returned with parts to re-route ducting around a leak and resolve the fault. Andre and his co-worker Brody were courteous, professional and quick workers and I was very grateful for their problem solving and professional service.
Matthew P.
Another amazing interaction with Alliance Climate Control. We had issue with our App interface so gave Jason a call, few minutes later Joseph called to inquire and decided to book an out call. Next day Andre and Kristian arrived, clean tidy and ready to help. In 10 minutes the issue sorted. I cannot speak more highly of the Technical Team and support, sooooo good. We have never been more impressed with the Alliance professional approach and support. Thanks Team.
Zara B
Have received consistently excellent service since 2023. Galvis and Damon were efficient, client-focussed, friendly, polite and explained everything we wanted to know about our system and components during our last service.

Couldn’t ask for better service (and my pets liked them which is always a good sign). Great people, would recommend to anyone.
Lucinda O.
Responsive, quick, communicative and really lovely to deal with. Will be using ACC again!
EDIT: ACC since came back and did an extensive install job - the team was so professional in their manner, the workmanship is fantastic and the final clean was so good it’s like they were never here.
Joanna C.
I highly recommend Alliance Climate Control. Thank you to Yunus and his team - Emre, Gokan, Cristian who did the removal and most of the installation and to Dragan and his team - Louis and Benjamin who finished off as well as Josh the electrician. I was very worried about replacing our old HVAC gas furnace with a new Electric HVAC. However, the professional team-based approach to the installation was highly efficient and I had nothing to worry about.

From the very start, James gave such a thorough and competitive quotation and answered all my questions. Yunus was so calm and accommodating as he lead the removal and installation and every member of the crew was so friendly and helpful. They went out of their way to ensure everything was left clean and tidy with great attention to detail.

Most importantly, we are delighted with the beautiful warm air circulating through our house.

Thank you! ¡Gracias! Tesekkürler! Hvala!
Wesley W.
The team had to come back to fix up a couple of things, easy to book and schedule, on time and sort out the problem

Edit: big shout out to Andre and Miguel

Today, 22.5.25 Alliance climate Control completed satisfactorily the replacement of my old AC system and installation of a new split AC System.
Firstly, Jake Perri inspected my site a week earlier and we agreed on his recommendation and price.
Today, the site team, Dragan, Louis and Benjamin were very polite, helpful and professional during the 3 hours that took to complete the works on a very rainy and wet day.
We discussed some details and issues before works commenced I was given the proper operational instructions.
I'm very satisfied with the work and operation of the new AC, even though, I have been using the system for a couple of hours.
Thank you very much for your assistance.
Regards,
Mario

Alliance have been servicing our Ducted Air Con for the last couple of years and they have always been very professional, friendly & helpful. Last week our Air Touch console was accidentally damaged & clearly needed replacement. Within a half hour of logging my repair request, I received a call from a lovely lady at Alliance who booked a service appt for the following week. Gabriel arrived with replacement console in hand. He was very competent, thorough & courteous - & kept me well informed as he installed & set up the new console. The Air Cond was up & running again, without hassle, in no time! Thanks Gabriel & the Alliance team!
CJ S.
Very professional, good system knowledge, provided options and worked to budget
