The Advantages Of A Multi Split Air Conditioning System

Multi Split Air Conditioning System

Every summer seems a bit hotter than the last, and it’s a trend that shows no signs of slowing. Next year is projected to be yet another scorcher, very likely even more so than this year! It’s hot enough to fry an egg on the sidewalk outside, so you rush home to cool off only to find it’s nearly as hot in there! What can you do to get some relief from all of this oppressive heat?

The answer is simple, have a multi split air conditioner installed in your home! Multi-split air conditioners are cost-effective and powerful, and they boast handy built-in features like air purifiers and ionisers, as well as Wi-Fi control and motion sensors. Their quiet running and amazing energy efficiency really shine when compared to wall and portable air conditioners. These are just some of the many good reasons why multi-split systems are Australia’s most popular air conditioners!

Let’s take a look at the features that place a multi-split system air conditioners a cut above the rest:

Traditional single-split air conditioners are only able to cool one room, whereas a multi-split air conditioner is built to cool multiple rooms all at the same time. Single-split air conditioners are comprised of only one compressor and just one air outlet, whereas the superior multi-split air conditioner is made up of up to five multiple air outlets that are all connected to one main compressor.

You have the option of mounting the interior units on the wall, ceiling, or floor, whatever suits you and your home’s needs, and all of them will be connected up to an outdoor compressor unit by power cables and refrigerant pipelines that are much easier to install than an invasive and complicated ducted system would be.

Every indoor conditioned air outlet can be controlled separately, even though they are all connected to the same outdoor heat pump unit that absorbs and disperses unwanted heat.

The multi-split-air conditioning unit is a great choice if your goal is to have air conditioning that reaches more than just one location inside your house, as well as giving you the ability to independently control each room’s temperature.

Some people ask why multi-split systems might be more desirable than ducted air conditioning that distributes cool air throughout the house via ducts? Both systems offer zoned cooling, but the methods of dispersing that cool air are different. Let’s take a look at some of the major advantages using multi-split air conditioning can offer you:

Convenience and Flexibility

Multi-split air conditioners allow you to choose the perfect indoor unit to fit each room in your home. Larger rooms like living and dining rooms can have a high-capacity system installed to ensure they stay nice and chilly. Smaller rooms like bedrooms and bathrooms are perfect for smaller units that run more quietly. All of these are connected to the central outside compressor unit, but you are able to conveniently control each unit individually, giving you complete mastery over the environment and temperature in every single room in your house!

Energy Efficiency

The ability to cool rooms on an individual basis is very efficient and greatly reduces energy costs. Being able to choose the perfectly sized air outlet unit for each room ensures that no power goes to waste! The operation of multiple indoor air conditioning units from a single external source is what makes multi-split air conditioning the leader in energy efficiency, giving you big savings when it comes time to pay the energy bill!


Multi-split air conditioning systems are designed to give you the utmost in peace and quiet so you will barely know they are running at all! You will enjoy the feeling of clean, cool air without all the racket that other systems tend to make.

The following is a summary of the advantages multi-split air conditioning units provide:

  • Efficient use of energy thanks to the system’s inherent flexibility
  • A single outdoor compressor unit powering multiple indoor air outlets
  • Being able to choose the most energy-efficient air outlet unit to suit each individual room in your home
  • Adjustable temperature settings unique to each connected room
  • Purchase is more affordable and installation much easier than ducted air conditioning
  • Extra air outlets can be added later easily as future needs require them to be
  • The maintenance, repairs, service, and unit replacements are all extremely affordable 
  • Quiet running


Multi-split air conditioner systems require professional installation. It takes the skills and training of a licensed air conditioning installation professional who knows how to handle the ozone-depleting refrigerant gas that the system uses. The indoor air outlet units should be installed as near to the ceiling as possible in every room because cool air is heavier than warm air and will flow down into the space naturally. The best practice for maximum cooling efficiency is to point the unit ‘s output louvres directly outward or tilted slightly up.

The placement of the outdoor compressor unit will need to be given careful consideration. An area that is shaded from direct sunlight is important, if that is not available, then the construction of a small sun shade over the unit is advised, which will help keep the unit cool as it cools your home! The unit should be installed on a hard, a firm surface close to the indoor air outlets, a purpose-poured concrete slab is ideal for this. The unit should be affixed to the wall by sturdy brackets to prevent dislodgement.

The Australian Government’s Department of Climate Change, Energy, the Environment and Water website has further information on air conditioning and heating systems that may be helpful to you. We hope that you have found the information in this article useful, and has demonstrated the many advantages that a multi-split air conditioning system has to offer over the alternatives so that you will consider installing one in your home.
