If you are after a unit that can both heat and cool however only wanted it for one room, a split system air conditioner is the ideal cooling solution. With new technologies continually being implemented, these hi-tech units have become much more energy efficient to run, keeping your cooling costs lower throughout the hot Melbourne summer months.

How do split system air conditioners work?

Split air conditioning systems are named because the system is split between the inside and outside of the house. The condenser is placed outside the house while the fan coil is installed inside. Heating and cooling works by removing warm air from inside the room, by the fan coil, which results in cold air recirculating the house.

If you’re looking for an air conditioner that quickly cools smaller spaces in your home – such as a single room – along with a unit that’s low maintenance and works quickly, and is easy to use –  then a split system air conditioner will be a great addition for your home.

If you need something a little more powerful, or to cool multiple rooms at once, you might consider looking at a gas ducted add-on cooling, or a ducted split system for your home.

Maybe you’re on a tight budget, but still need an effective air conditioning solution that will effective solution that will use less energy and be kinder on the environment? If this is the case, then perhaps you might consider evaporative cooling.

What are the different types of split system air conditioners?

When it comes to split system air conditioners, there’s basically two main types that we work with at Dias Air: a split system option and the wall mounted split system.

  • Doors & windows can be left open

  • Won’t dry your skin, nose and eyes
  • Whisper quiet cooling


Evaporative cooling is the cheapest way of cooling your home, without compromising on cooling efficiency. Running costs are very low so you can have control over energy bills while enjoying a comfortable and cool environment.

How does evaporative cooling work?

As the name suggests, evaporative cooling systems works by evaporating moisture in the air. This is achieved by drawing in outside air through a moist pad, and then cooling and humidifying the air through the pad before it is circulated through your house.

Evap cooling is available in ducted, wall-mounted and portable units, and work best in hot, dry conditions, which makes these systems suitable for Melbourne.

Is evap cooling the best air conditioning system for me?

If you’re looking for a highly efficient, cost effective cooling system that has low impact on the environment by reduced greenhouse emissions, then consider an evaporative air conditioning system. If you suffer from dry skin and eyes, then evaporative cooling may also be great option for you.

Evaporative cooling generally works best in hot, dry conditions – which makes it an excellent choice for the hotter, dry Melbourne summer months.

What are the different types of evaporative cooling systems?

Ducted evaporative coolers are available in both standard and inverter models. Inverter models have a variable speed (or inverter-driven) motor, resulting in lower running costs.



  • Whole home heating & cooling
  • Visually less intrusive
  • Zoned distribution
  • Very quiet system
  • Central temperature and zone control


Ducted split systems are used to both heat and cool your entire house, and are considered the ‘bigger brother’ to the wall mounted split system. Unlike the wall mounted split system, the ducted split system can cool all rooms in your house simultaneously by distributing air through concealed ducts in each room.

The ducted system can be installed in a new home or tailored to suit an existing one. Once installed, only the controller, the return air and discharge grilles are visible, making it a sleek, discreet air conditioning solution for your home.

How do ducted split system air conditioners work?

Ducted Air Conditioners consist of an indoor and outdoor unit and flexible ducting. The indoor unit is concealed out of sight, in your ceiling or under the floor, with flexible ducting distributing conditioned air through vents located throughout your home. An outdoor unit is positioned in a discreet location outside your home.

Is a ducted split system the best air conditioning system for me?

If you’re looking for a top of the line system for both heating and cooling your entire house, and are willing to invest a little more upfront – then a split system air conditioning unit could be the perfect option for your home. These systems are highly efficient, effective and reliable and the initial investment will most certainly pay off in the added comfort you’ll receive from a ducted splitn system.

By using strategically placed vents in rooms throughout the home, you’re able to have different rooms at different temperatures, which gives added flexibility and comfort depending on personal preferences.



  • Whole home heating & cooling
  • Easy installation
  • Visually non-intrusive
  • Cost effective
  • Zoned distribution
  • Low allergens
  • Very quiet system


This unit is an add on to your existing gas ducted heating system allowing you to heat rooms through through your existing heating ducts. This can be a cost effective method of cooling your home using existing components and providing cooling to the entire house.

How does add on cooling work?

The main components are the heater and add on coil with an outdoor compressor. During heating the heater is a basic ducted heater, which doesn’t need the other components. The add on coil is an ‘in line’ unit – during cooling, refrigerant passes through a system of piping inside the coil. The fan from the heater is then activated and air is passed through the coil, conditioned and sent to the rooms. The heat absorbed refrigerant is then sent to the outdoor unit and expelled to the atmosphere. This process gives the user efficient warm air during winter and cool refreshing air during summer- a perfect option for those that want the most efficient and effective system all in one.

Is add on cooling the best air conditioning system for me?

Do you have an existing gas ducted heating system? If so, then an add on cooling air conditioning system is probably the easiest, best suited solution for cooling your home in Melbourne’s hotter summer months. As you’re only adding to your existing unit, the cost of installing an add on cooling unit will be lower than installing a complete new air conditioning unit.
