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.


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?


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.


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 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.

Chris and the team took on a niche home networking job for me to cable up 12 runs across 5 rooms.

From the start I was consulted with on different options, fantastic communication throughout and an absolutely stellar end result. Massive thank you to Chris who was present throughout and handled the job with ease, though I know it wasn't simple. Thanks again team!read more
