Air Conditioning Units

Air Conditioning Units

Inverter Split Systems

An inverter works by constantly changing the fan and motor speed of the air conditioner so it can reach the required temperature quicker. Once the Inverter range reaches the desired room temperature it adjusts to maintain perfect comfort. This makes the Inverter Units more economical, quiet, and efficient to operate.

Rather than use a constant speed compressor, the inverter system uses a variable speed compressor, which means the Cooling or Heating capacity of the air conditioning system can be varied to suit indoor conditions in each room.

This makes the Inverter Systems more economical and efficient to operate and produce less noise than standard counterparts on the market today.

Multi Head Inverter System

What’s a Multi Head Split System Air Conditioner?

Split air conditioners are powerful and cost-effective, known for their quiet efficiency compared to window, wall and portable air conditioners. In fact, they’re the most popular type of air conditioner in Australia. But did you know there are actually two types of split air cons: single split air conditioners and multi split air conditioners.
If you’re not sure what a multi split air con is, or how it’s different from a single split air con, relax. We’ll take you through everything you need to know about multi split air cons.

All split systems are quieter, more powerful and energy efficient than window/wall and portable air conditioners. Many split system air conditioners also come with handy built in features such as motion sensors, Wi-Fi and air purifiers or ionisers.

So, what else makes a multi split system air conditioner different from the rest?

A multi head split system air conditioner comprises a compressor – the outdoor unit – which can be used to power two to five heads normally (or up to 14 with a Daikin VRV-S). The head is the name of the indoor fan coil unit. The head can be a wall split, cassette, floor console, bulkhead or ducted system or any combination of these.

The indoor Hi-Wall Split system head is identical to those found on a standard Inverter Split System with identical features and benefits, the outdoor unit however is far more sophisticated and can independently control each separate indoor unit.

When to Use a Multi Head Split System

  • A multi head split system is used instead of several wall splits(or other room split system) so that you don’t need several outdoor units spoiling the appearance of your home or taking up valuable space
  • Instead of an expensive ducted reverse cyclesystem
  • where there is not enough roof space to fit a ducted system. This is often the case with flat roof homes
  • in a double storey home where there are no penetrations (space to fit ducting from the roof to the ground floor)

Can You Convert a Split System into a Multi Split Air Conditioner?

The question we are most often asked is, “Can You convert a normal split system into a multi room split system air conditioner?” Unfortunately, no you cannot. Whilst the indoor and outdoor unit of a multi room split system may look the same as a standard wall split, they are different.

There is good news however. You can add a further head to an existing multi split as long as the outdoor unit is sized to heat or cool the larger area.

Multi Head Split System or Ducted. Which is Best?

A multi split system air conditioner provides more flexibility than a ducted system. A multi split has one controller per head so you can control the temperature and airflow in each room however all indoor units typically must be set to the same mode such as Heat or Cool. A multi split system cannot independently produce heating and cooling function to multiple indoor units at the same time.

The running costs of a multi head split system are lower than many ducted reverse cycle air conditioners as each head is sized for and treats just the room you are using. Ducted systems need internal doors open for air to flow to the return air grille (The big grille typically in the hall that takes all the air back to the indoor unit in the roof space for further heating or cooling).

The temperature sensor is in the room being heated and cooled so you get a more accurate temperature reading. With a ducted system the temperature sensor is at the controller or the return air grille unless you spend extra to get a sensor installed in each zone.

So Why Aren’t Multi Head Split Systems More Popular?

The main reason multi head air conditioners aren’t more popular is cost. Per kilowatt of heating and cooling output, multi head split systems are more expensive to buy than wall splits or but typically cheaper than a fully ducted system. You have to buy a specialist multi-head outdoor unit which is relatively expensive.
You also need more refrigeration pipework and electrical cabling than ducted reverse cycle or standard wall splits as each head is run back to one outdoor unit and that cost can be significant.

Pros of a multi split system air conditioner

Here are many great reasons to consider a multi split air conditioner to keep your home cool in summer and warm in winter. Here are some major advantages of using multi split AC:

Flexibility and convenience

Multi split system air conditioners offer unsurpassed flexibility and convenience, allowing you to choose the right indoor unit for each room of your house. You can install a high capacity air conditioner for larger living rooms and smaller, quieter ones for the bedrooms, all powered by the one outside unit. This allows you to control the temperature and environment in your home on a room by room basis.

Energy efficiency

Energy saving settings, combined with the ability to heat or cool individual rooms, helps to reduce power and running costs. Choosing the right indoor air outlet unit to suit each room also ensures that you’re not wasting power. The wrong unit in a room can result in the air not being cooled properly and energy wastage. A unit that’s too big for a smaller room also uses more power every time you turn it on compared to a smaller unit running for a longer period of time.

By operating multiple indoor air conditioners from the one external condensing unit, multi split system air conditioners are among the most energy efficient of all air conditioners. Choose the most energy-efficient indoor air outlet units for maximum savings on your power bill.


Multi split air conditioning systems are peaceful and quiet.

Independent control

By enjoying the ability to individually adjust the temperatures in each room, you’ll save money and optimise comfort by heating or cooling individual rooms. You can have up to five separate indoor air outlets, all powered by a single outside compressor and controlled by a wireless remote or optional wired wall controller.

Summary: Advantages of multi split air cons

Advantages of multi split air cons include:

Energy efficiency
Multiple indoor air outlets powered by the one outside compressor unit
Ability to choose the most suitable and energy efficient air outlet unit on a room by room basis
Adjusting temperatures to suit each room
More affordable to purchase and install compared to ducted air conditioning
You can add in extra indoor units later on down the track if needed
Affordable maintenance, service, repairs and replacement of units

Cons of a multi split system air conditioner

Multi split air conditioner power consumption

A multi split air conditioner usually consumes more energy than just the single split air con, so it’s important to choose the capacity for each split air con carefully to preserve energy efficiency.

Restrictions on placement

Outdoor condensing units need to be placed as close as possible to the indoor air outlet units. Also, the indoor air outlet units require a relatively large amount of free wall space to be installed.

Interconnection can create problems if the air con fails

If something goes wrong with the outdoor unit, all indoor air outlets connected to it will be affected. This means that if the outdoor compressor dies in the middle of summer, you won’t be able to cool your home until it’s fixed.

Summary: Disadvantages of multi split air cons

Energy consumption must be well-planned
Outdoor air compressor placement must be close to indoor units
Compressor failure shuts down entire system

Installing a multi split system air conditioner

A multi split system air conditioner needs to be professionally installed. Due to the ozone-depleting refrigerant gas used in air multi split system air and other air conditioners, they must be installed by a licensed air conditioning installation professional.

Your indoor air outlet unit should be installed as close to the ceiling as possible in each room. Cool air is heavier than warm air, so for maximum cooling efficiency point the louvres on your unit directly out or slightly tilted up. To heat the room, point them downwards.

You will need to give some consideration to where to place the outdoor compressor unit. Ideally, it should be shaded from direct sunlight and installed on a firm surface such as a concrete slab or attached to a wall with sturdy brackets. It should also be installed as close to the indoor air outlets as possible. Large and multi-storey homes may require more than one outdoor unit in order to be able to run the piping from the outside unit to the indoor air outlet.

Ceiling Cassette Inverter System

If you’re looking for a new air conditioning system for your home, business, or property, you’ve likely looked into several different options. You’ve considered split systems and ducted systems. But have you ever heard of ceiling cassettes?

Ceiling cassettes are unique because they don’t sit in your window or on the wall; they mount on your ceiling. These units work with most standard ceilings.

Many offices and businesses prefer ceiling cassettes because they cool a wide area, but the units don’t take up much space. Today, many homeowners are starting to prefer ceiling cassettes as well.

Read on to find out why a ceiling cassette system might be right for you.

  1. It’s Ideal for Small Spaces

If you live in an apartment or work in a small office, a ceiling cassette system is a good choice. That’s because it doesn’t crowd you by taking up needed space. It doesn’t protrude from your window ledge like a window unit or jut out of the wall like a wall-mounted unit. Instead, it does all its work from the ceiling.

Commercial businesses enjoy the ceiling cassette’s compact size, which doesn’t take up space they need to display their merchandise.

  1. It’s Subtle, Yet Classy

Because the ceiling cassette is small and simple, it fits into any type of design plan. In fact, the only part you’ll see of the unit is the thin fascia panel. This modern style works just as well in a home as it does in an office or commercial building. The cassette units are extremely discreet with only the grille showing in the ceiling

  1. It’s Easy to Maintain

A ceiling cassette AC system should function for many years without problems. You simply need to turn off the power and wipe it with a dry cloth about every two weeks. You should also check and clean the air filters.

  1. It’s Quiet

We’ve all been in homes or businesses where the sound of the air conditioning unit was loud enough to drown out conversation. Fortunately, the ceiling cassette does its work quietly, much more quietly than conventional units. And its removed location means you likely won’t hear it at all-unless you look up at the ceiling, you won’t even know it’s there.

  1. It Reaches a Cool Temperature Quickly

With a ceiling cassette, you don’t have to sweat in an uncomfortable room, waiting for the unit to reach your desired temperature. The automatic fan turns at an initial high speed to quickly reach the right temperature.

  1. It Covers a Wide Area

Ceiling cassettes are typically more powerful than wall-mounted units. The most effective units feature four-way airflow, sending air to every corner of the room. Four-way airflow not only cools a wide space, but it ensures every area of the room maintains your desired temperature.

  1. It’s Energy Efficient

With new advanced technology, your ceiling cassette reduces power usage as soon as it reaches the right temperature. This allows it to use less energy and save you money on utility bills. You can also adjust the temperature, so your unit doesn’t work harder than it needs to.

Air can be delivered in up to four directions, giving the room an even temperature distribution

A highly efficient fan design, its wide airflow distribution ensures even temperature distribution

Weekly timer allows you to plan your usage, helping you save on your power bills

  1. Higher capacity than a split system

Ceiling cassette systems range from 2.5 kw up to 14.0 kw so they are able to be used in a wide range of application especially in large open plan living areas where even the biggest split system is not sufficient to heat or cool the area effectively.

A ceiling cassette system can provide similar capacity to a ducted system at much less expense and can even be ducted into an adjoining bedroom or office.

  1. Control Flexibility

Ceiling cassettes have the option of either a wired backlit wall controller or a conventional remote control and some models even incorporate Wi-Fi so you can control the system with your Smartphone.

  1. Flexible installation options

Ceiling cassette systems are installed flush with the ceiling and incorporate a built-in drain condensate pump that can pump 850mm vertically. The interconnecting pipes and electrical are run through the ceiling which gives you great flexibility in selecting the outdoor unit location.

With the Samsung 360 ceiling cassette system you have the option of a square or round fascia to suit your desired look.

Floor Mounted Inverter System

Designed for applications where wall space is at a premium or where a wall mounted system is not suitable, floor standing systems are comprised of an indoor unit which is installed on the wall, close to the floor and can be semi-recessed into the wall and an outdoor unit which is placed on an adjacent wall on the exterior of your home.

Coming in a range of sizes and being reverse cycle, floor standing systems are suitable for heating and cooling a single room such as a lounge room or medium sized bedroom.

Floor Cassette systems can also be ceiling mounted for additional flexibility but are most suitable where there is no wall space available or to replace an existing floor mounted gas heater or split system air conditioner.

Are you limited on wall space in your home, yet you want to install an air conditioner? Do not worry, it is now possible to install a floor air conditioner to help with all your cooling and heating needs. This type of air conditioner is also called a floor console or a floor standing air conditioner.

Usually, the air conditioner unit is installed on the wall or a ducting system is used which is installed in the roof space. However, increasingly, property owners are preferring to install a floor standing air conditioner for their rooms for a variety of reasons.

A floor standing air conditioner unit is similar to the conventional split air-conditioner. The main difference is that it is mounted on the floor or very close to the floor. In some cases, if the floor is recessed, the air conditioner can be placed on it. In other cases, it can be placed below the window. Compared to other air-conditioners, this style of AC unit is compact in size. The air-con unit is similar to other air-conditioners in design and it works identical to a wall-mounted system. It has a filtration unit for removing the dust particles, turbofan, refrigerant and compressor for cooling & heating. Some units have auto-swing louvres to adjust the direction of the cooling.

When to use a floor mounted air conditioner?

A floor-mounted console is often used when it is not possible to install the indoor unit of a standard air conditioner which normally is mounted on the wall. This is often due to limited space on the walls or even in the last few decades many buildings have glass walls and large windows. So, installing a split wall unit is not possible in such cases and that is where a floor console is preferred.

There are some rooms and areas where the wall is difficult to access. While in other areas, the ceilings are low or angled, leaving very little space for a split wall system installation.

In many homes, the wall is used to display artwork such as paintings or other items of decor. Installing a split air conditioner on the wall will affect the appearance and décor of your home. Therefore, in these cases, a floor-mounted system is preferred since it can be placed in any corner of the room and serve the same purpose.

Ultra Cool have extensive experience with installing a range of Floor mounted inverter systems Inc Fujitsu, Mitsubishi Electric and Daikin.

Ducted Inverter System

Through new, advanced technology, the Inverter Ducted Systems are more economical to operate and quieter to run than conventional units. They can handle greater extremes in temperature, are smoother and more stable in operation and reach the desired temperature more quickly than conventional air conditioners. The Inverter component allows the outdoor unit to vary its speed and output to match the required capacity of the indoor unit. Thus, the Inverter model can achieve 40% more operating efficiency than conventional models and therefore, is much cheaper to run.

Zoning:   A ducted system is zoned to enable the user to select the area of the home or office that is to be air conditioned

A typical layout may be:


Zone 1: Master Bedroom

Zone 2: Kitchen and Dining

Zone 3: Living Room

Zone 4: Bedroom 2

Zone 5: Bedroom 3

Zone 6: Bedroom 4

Zone 7: Office

Zone 8: Media

Flexible control

  • All our Ducted systems Include a backlit wired wall control with optional Easy to use 8-zone integrated controller and optional Wi-Fi connectivity so you can control your entire system with your Smartphone

Zone System Upgrades

Many older Ducted systems were installed with what’s called a Day/Night Zone system which utilised 2 switches on the wall marked Beds and Living. This system would only allow the user to have either all the bedroom on or off and the rest of the house either on or off with no ability to individually control different areas of the house with one area usually left permanently on which is referred to as a spill zone.

Some Zone systems are a slight step up from this but typically incorporate only 4 Zones, with Zone 1: Master Bed, Zone2: Living, Zone 3: Dining, Zone 4: Beds. This is operated by simply pressing a button on the Zone Control panel but still does not allow for individual room control and typically incorporates a spill zone that cannot be turned off.
