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.

Is VRV Air Conditioning Right for Me?

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. High comfort and low humidity are what this air conditioning system specialises in. 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.

If you want to know more about VRV air conditioning systems, have a chat with the experts at Alliance! Our team will determine if this system is right for you and walk you along the next steps. Give us a call now!

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.

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.

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.
Christian Claye E.
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
Mario V.
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

Repair people were prompt, polite and efficient

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
