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.

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.

We were delighted with our experience with the Alliance team of Tommy, Nick and Luan. They went about the job professionally, expertly and with no fuss. They left the job site as they found it, perfectly clean. What a wonderful example of hard working young men and a credit to your organisation. All contacts with these young men were courteous and polite. Well done Alliance.

ACC were fantastic - Had a broken mainboard in my dankin unit. Need parts which would take up to a week. They offered me a portable aircon to help with my sick kids temp issues and it kept us happy until the part arrived. The work was done quickly and easily and the aircon after a service and new mainboard is better then ever.... Insanely good service and will be 100% keeping these guys on speed dial for all my aircon needs at my investment and home property ongoing .

Very impressed with the quality of service and professionalism from Alliance Climate Control. The initial consultation was thorough and considered, the installation was very clean and respectful, and the back-end admin and communications were easy, straightforward and transparent. I'm very pleased with final product (ducted Ac). I've no hesitation in recommending Alliance. Thank you James, Ken, Shadi, Trung, Harry and Jason! You did a great job!

Dealing with Alliance was a smooth experience. With my ducted air conditioning system failing and summer approaching, I anticipated getting quotes and scheduling installation would take a long time.However, just a couple of days after my initial quote request, a representative came over and explained my options, following up the lot clearly via email.Once we decided on the best option for our needs and made the call, the installers arrived within a week.Installers were friendly and professional, double-checking everything before starting the installation and cleaning up thoroughly afterward.We are delighted with the service provided, and our home is now ready for summer! I strongly recommend their services! 👌Thank you Alliance!

This in extremely hot conditions. All the staff are friendly and take pride in doing a good job.Thanks Jane

Thank you once again to the team at Alliance Climate Control. This was one of the smoothest home renovation projects I've experienced.My previous air conditioner was a complete nightmare after installation—I bought it from a certain large electronics store that handed off the job to unreliable third-party contractors. Within months, it started leaking from the base and couldn’t drain properly, it was angled weirdly. It became one of the most stressful events for me, especially during summer when we relied on the air conditioning. The constant repairs and cleaning added up quickly in both time and costs.When I finally surrendered and started to do my research i came across Alliance Climate Control. They not only promised to fix the issue but also ensure me they will install a new air conditioner the right way (they even stated this on their website - where they will make sure you are satisfied will their work before they finish). So when the team arrive, Kevin and Dragan took on a challenging job—my old unit was installed in an awkward position, with improper drainage and poorly done piping within the walls. But they were undeterred. They assessed the setup carefully, discussing how to best resolve the issues rather than just doing a quick install and leaving.Their attention to detail was impressive, and they left my place spotless after the job, ensuring I wouldn’t have to clean up after them. safe to say - my room is now cool and ready for the summer heat!The takeaway here: don't go with just any third-party installer. Air conditioning installations are complex, and cutting corners can cost you more in the long run. Alliance Climate Control's high ratings speak for themselves—they know what they’re doing.Thanks again, Kevin and Dragan—I truly appreciate all your help!
