What is Multi-Split System Air Conditioning?

A multi-split air conditioning system is an air conditioner that features one outdoor compressor that connects to multiple indoor units. Instead of using ducts as a ducted system would, these indoor units are instead connected by refrigerant lines through your house. Up to eight indoor units can be connected to a multi-split system, although they are more commonly seen with five or six units connected.

Because the refrigerant lines connect each indoor unit straight to the outdoor compressor, each indoor unit can be a different style. That means you could have a wall-mounted air conditioner in one room, and a ceiling cassette unit in the next.

These systems give you the ultimate flexibility when it comes to configuring the cooling system for your home. From size to style, you can customise a multi-split system to perfectly suit your home. The ability to customise these systems, make them an extremely popular system across Aussie homes and businesses.

If you think a custom multi-split system air con is the solution your home has been looking for, give the experts at Alliance Climate Control a call. We can help you design and install your perfect cooling system.

What Are the Benefits of
Multi-Split System Air Conditioning? ​

With one of the most unique designs in air conditioning, there are lots of benefits to a multi-split air conditioning system. This versatile system is cheap, efficient, and makes for a great addition in any home, office or apartment complex.

alliance-icon

Zoned Cooling

The only air you’ll get with an evaporative cooler is completely clean, fresh air. Any air that comes into your home through the evaporative cooler is clean air taken from outside. Once the air is cooled and circulated through your home, that stale air exists out of a window, instead of being recycled through your home. Only using fresh air, instead of recycling stale air, is a huge benefit for those with sensitive skin or allergies.

Great For Large Spaces

A multi-split system is perfect for larger homes, because you can have multiple indoor units. If you have a large home, an office or a small apartment building, having a multi-split air conditioning system will let you have different units in different rooms that can be controlled individually. You can have up to eight different indoor units connected up to one multi-split air conditioning system. Because each indoor unit is connected to one main outdoor unit, this space-saving design lets you cool a huge amount of area without needing much room to house it, and lots of time to install it.

Indoor Unit Flexibility

A multi-split air conditioning system allows you to have different air conditioning units in each room in the house. Not every room is the same in any home, so why should they all have the same type of air conditioning unit? When installing a multi-split air conditioning system,

you can choose between these air conditioning units to install in each room, connected to the same system:

Is Multi-Split System Air Conditioning Right for Me?

Multi-Split-System-2

At Alliance, we understand it can be difficult deciding which air conditioning system is right for you. That’s why we are here to help.

If you have a larger home, would like to zone your air conditioning or just like the ability to have different air conditioning units in each room without losing efficiency, then a multi-split system is right for you.

Multi-split system air conditioners give flexibility in a way that no other air conditioners do. You won’t have to worry about crazy installation fees, because the system is cheap enough to run that before long it will have paid for itself.

A multi-split system is also quiet, responsive to changing heat loads and reduces power demand thanks to its high coefficient of operating performance. If these elements all appeal to you, there is no reason you won’t love a multi-system air conditioner.

The best part: Alliance can customise a multi-split system to suit your home. So if your house is large, or has an unusual design, a multi-split system gives you the ability to tailor your air con system to your home. For more information on these custom services, give the Alliance team a call today.

What is a VRV Air Conditioning System?

A VRV (or variable refrigerant volume) air conditioning system is one that delivers just enough refrigerant to each connected indoor air conditioning unit to meet its cooling needs. Unlike other systems, a VRV system will detect when a room is no longer occupied and will stop sending that indoor unit refrigerant. As a result this lowers its emissions and operating costs.

VRV air conditioning systems are large scale and can have up to sixty-four indoor units connected to just one outdoor unit, making it perfect for commercial buildings, offices and large apartment blocks. You can customise the location and layouts of the indoor units to best suit your location.

VRV air conditioning is one of the cheapest and most efficient ways to connect that many indoor units from a single outdoor unit. This is why it is so popular among homes and businesses across Australia.

If this sounds like the custom air conditioning system you’ve been looking for, don’t keep waiting on it! Alliance Climate Control can install your custom VRV air conditioning system. Give us a call today to get the ball rolling.

VRV Air Conditioning

What Are the Benefits of VRV Air Conditioning? ​

VRV air conditioning is a sophisticated system that can run over fifty indoor air conditioning units from a single outdoor unit. But the sheer size of a VRV air conditioning system isn’t the only attractive feature of the system. There are many benefits that come with installing a VRV system in your offices, apartment block or commercial building.

Automatic Comfort

A VRV air conditioning system will automatically adjust the interior temperature of each room to a comfortable level. If a room is too hot or cold, the system will use a tiny amount of energy to send enough refrigerant to that unit to maintain a comfortable temperature in that room. Additionally, this feature will automatically reduce the humidity in the air. The way the system can automatically adjust so many rooms at once to maintain a comfortable level is one of the biggest selling points for a VRV air conditioning system.

Cooling And Heating Provided

Unlike other air conditioning systems, a VRV air conditioning system can provide both cooling and heating options. This system will passively heat or cool each connected room until it’s at the predetermined, comfortable level. That means no matter how hot or cold it is outside, it’s always going to be perfect in each room.

Silent Air Flow

Because the primary motor of a VRV air conditioning system is outside, it’s almost completely silent; no more noises and vibrations coming from loud indoor units. A VRV system is going to keep your room cool without disturbing your work or your sleep.

alliance-icon

Energy Efficient Design

A VRV air conditioning system runs at a lower capacity for a smaller amount of time throughout the day, making it far more energy-efficient. This system harnesses and uses hot and cold air to regulate a specific indoor temperature. Because it’s harnessing already hot or cold air to maintain a constant temperature, it’s using far less energy than other fans and air conditioners would. Not only does that make it far more energy-efficient, but it’s cheaper to run as well.

Choosing the Right Ducted Air

VRV air conditioning systems are perfect for anyone wanting to maintain a comfortable temperature level in multiple rooms all year long.

So, if you are looking for a cooling system that produces consistent comfort levels, flexible zoning options and lower energy costs, the VRC air conditioning system is for you.

If you have a small, one-bedroom apartment, a VRV system is not going to be a great investment. But the more rooms you need cooled, and the more efficient of a system you require, the more a VRV system becomes the perfect choice for you. If you work in an industrial building, large office, hotel or corporate building, a VRV air conditioning may be perfect for you.

Is VRV Better Than Multi-Split System Air Conditioning?

VRV air conditioning is better than multi-split air conditioning in larger buildings with lots of rooms. VRV air conditioning works similarly to multi-split air conditioning. Both connect multiple indoor units to a single outdoor compressor. The first major difference between the two types is that VRV air conditioning is built for large-scale buildings like large office blocks and hospitals, while multi-split systems are more commonly found in large homes and small office blocks.

The other difference is that a multi-split gives you greater control over the temperature in each room, while a VRV system works best to maintain a constant, comfortable temperature and humidity across multiple rooms. If you are looking for an air conditioning system for a large home, a multi-split system may be better, while a VRV system is going to be far more effective in a large office block.

Mel S.
The team was friendly, efficient, and highly professional throughout the installation of our air conditioner. Everything ran smoothly, and we couldn’t be happier with the result. A special shout out to Jiayi Gino who managed the project and the team. Highly recommended!
Lisa H.
Vy, Luan and Kim spent two days replacing our out dated air-conditioning unit dealing with issues with the tight installation space. I was kept informed the whole time in any issues they had and they were really polite and respectful. They did a great job in cleaning up after they finished. Very happy with their work
Leslie B.
Jonathan, Peter, Adrian and JJ installed a couple of air conditioners at my home. Polite and professional, they consulted me at each decision point, offering options and recommendations during the installation process. I highly recommend them.
Update 15/8/25: while comparatively expensive to others, I think it's fair price given the quality and depth of backup service. I've had some issues with the units, but they were resolved. Recent servicing and support from Damon was was superb.
Jola S
Very happy with the quick turn around of a fairly complex job. The crew were friendly and very polite and explained everything clearly. Once the job was finished the clean up was thorough and they left my pace immaculate. Definitely would recommend the service

John O.
Very happy with the A/C service provided by Alliance. Their service technicians are always polite, respectful and professional.
Anna & J.
The Team from Alliance were everything you need from trades. I was able to get an appointment within the week to assess what was wrong with air conditioning. Then when it came to installation they were flexible enough to shift the date due to wet weather which would have meant 5 days with no heating. Everyone was always polite and explained everything thoroughly. Site clean up was exceptional. I would Definitely recommend to a friend.
Ruby C.
Very thorough, good listener and very professional. I'm grateful.
Patricia F.
Hi this morning I had Tegan from Border Heating and cooling come to my home to assist me with problems with heating my home. Tegan is so knowledgeable about all products and helped me so much. Tegan gave me very good tips and information to help, and was so honest with that advice, that will cost me much less than I thought. Thank you Tegan for all your advice and help today, I have a plan ahead now and it’s well in my budget. I am a return customer for Border Heating and Cooling in South street Wodonga, I have only great things to say about this business, and would recommend them to anyone needing assistance with heating and cooling their property.
Gary C.
Clearly explained procedures and fast, prompt and friendly service.

Fantastic service from start to finish.
Kind, polite, professional team members who explained the work to me so I understood all charges. So clean too. Strongly recommend. So glad I found you guys - thank you so much. I’ve never felt so cosy upstairs thanks to finally fixing my ac unit.
Brett L.
Have been using for many years now. They always arrive within the allotted time, explain the different options and do a thorough job whether a service or clean
Camilo V.
Recently, Alliance installed a full ducted air conditioning system in my apartment, replacing the existing split system. They helped me to choose the perfect system for us, were able to use some of the existing infrastructure, which helped avoid any damage to the common property areas of the building.

Their proposed solution was excellent, and they handled all technical challenges with professionalism, giving me great confidence in their work. Gareth and his team were fantastic—careful, respectful, and left everything spotlessly clean.

The plasterer, Harry, was incredibly precise and did an outstanding job. We couldn’t be happier with the result and are really glad we chose Alliance. It was a great decision.
John S.
Really happy with the service done by Alliance's technicians. Very prompt, responsive and polite. They even came with boots cover to keep our place clean and tidy when they came and do our AC service and maintenance. Thanks Shazim!

Was so happy with their service, we decided to use them again for another installation. B.J. and Christian were very prompt, kept the place clean and tidy and the whole installation process was very smooth. Thanks again guys!
Daniel M.
Galvis did a great job of explaining all the options and was able to complete the work in a timely manner. Thanks!

I would like to say a big thank you to the team at Alliance.
This is how a company should operate. Professional, Courteous, Helpful in all details from the quote supplied by Shazim, to the installation team lead by Matt, Benjamin, Ahmad, Qaig and Casper. They had to perform their work in very trying conditions due to persistent heavy rain. The installation process lasted 3 days. What impressed me was their work ethic and attention to detail. We have had numerous trades people to our house and this team is right up there with their workmanship. I would also like to thank Michael and James who are the operations experts , who responded to my query within the hour. They arranged for Andres from Alliance to be at my house within the hour and the matter was resolved . I have no hesitation in recommending Alliance.
Bon S.
Very happy with the Alliance team, who installed a multi head A/C (three indoor units) at my home.

We knew from the outset it would be a difficult installation due to my apartment's layout, but the installers managed to complete the work efficiently, and did a very neat job. They were friendly and professional to deal with, taking the time to explain everything they were doing and ask lots of questions to ensure I was happy with the placement of all components. They were also careful to protect my floors and furniture from dust, and cleaned up thoroughly when they were done, leaving everything looking immaculate.

Highly recommended.
Sarah F.
Thought the reviews were too good to be true, but I would add my good review to this. Very thorough, helpful and efficient! Highly recommend
david K.
Dan and Nik did a great job. Special thanks to Alex for taking the time to fix a niggling noise issue. Happy to recommend.

Great service. Listens to concerns and checked everything out. Went above and beyond to ensure the air con system was running to optimum performance.
John C.
Qais & Sayed & Maisam were very professional and lovely people to work with
Everything was explained well and they worked to get the job done efficiently
Greg M.
BJ, James, Ahmad Gais and all the other guys did an amazing job organising and installing the system flawlessly and neatly so the unit is barely noticeable inside and cleverly installed outside with power supplied inside the wall cavity with minimal exterior visibility. As an engineer myself I was impressed with their efficiency and polite manner and patient explanations and discussions of our needs. Good job guys.!
Gaj P.
I had an outstanding experience with Alliance Climate Control! The team that came out to install my new air-conditioning system—BJ and Ahmad Qais—were phenomenal. From start to finish, their communication was clear, professional, and timely. They explained everything in detail, ensuring I understood the process and answered all of my questions.

Their professionalism was top-notch, and you could tell they really take pride in their work. The installation itself was flawless, and they worked efficiently without compromising quality. What really impressed me was the attention to detail and the quality of their post-work cleanup. They left my home spotless, which I really appreciated.

I highly recommend Alliance Climate Control and will definitely turn to them for any future HVAC needs. BJ and Ahmad Qais are a credit to the team!
Catherine A.
