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.

Is Saying About Alliance

Based on 2503 reviews

Peter

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,

Kind regards
Peter & Michelle

A terrific job. Took great care in doing all that was required and left the place clean and tidy afterwards. Polite and respectful team. We are enjoying having aircon finally!

Donna C.

Jason was extremely helpful fixing our aircon unit. Arrived on time and kept me updated with his whereabouts, he diagnosed the problem quickly and completed the repair efficiently. My AC is running perfectly now - highly recommend.

George D.

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. 👍👍👍

After three years of trying to get my system working correctly, and thinking I was going mad, Yasim came out with his expertise and found several issues with the initial installation. Thank goodness Alliance has a super hero who sorted my issues once and for all. Need more training for installers to take pride in their work and not rush to get the job done quickly.

We couldn’t be happier with the outstanding service from Alliance Climate Control! The team delivered a truly seamless installation of four split systems at our home (Service Ref. #101598) from start to finish.

A special commendation goes to Ahmad Maisam and Meedy for their exceptional leadership, organisation, and genuine care in addressing our needs. Their professionalism, clear communication, and attention to detail made the entire process smooth and stress-free.

The workmanship was excellent, the team was punctual and respectful of our home, and everything was left spotless at the end. Simply put—the best team ever. Highly recommended to anyone looking for top-tier air conditioning service!

Excellent service from start to finish..after contacting 2 prior air conditioner companies weren’t interested in doing the job , I found Alliance recommended by my friend Vicki .. highly recommend

Craig L.

We were very happy with the work undertaken by Dylan last week. He was very courteous and professional. He answered our questions very clearly and investigated the 2 issues we raised very thoroughly.

Laura

The team who attended my home last week to install a split system were impeccable - Gokhan, Louis and Rodrigo - as was Errol who attended to provide the initial quote and the office team when I called with some questions pre-installation. Everyone was helpful and professional. They set high expectations and delivered!

Christian B.

Andres from Alliance was excellent, professional and very clear. Our units are now operating perfectly and he detected a major issue and presented multiple solutions. Would recommend the service highly.

Sky S.

I couldn't be happier with the excellent service and clean provided by Emre.
He was punctual, thorough with his assessment of my aircon units and managed to identify the source of why my aircon has a mouldy smell. He was professional, knowledgeable and clear with his explanation of what can be the problems as well as recommending appropriate options to address the problems.
5/5 will call upon his services again if my aircons ever give me grief (though I doubt it with the level of servicing he performed).
