Evaporative Cooling is by far the cheapest option to cool your entire house. Depending on the size of your house, the unit could cost as little as 17 Cents a day to run.
Benefits of evaporative cooling:

  • Highly cost effective
  • Low greenhouse gas emission
  • Super quiet
  • Doors & windows can be left open
  • Won’t dry out your skin, nose and eyes

Add-on cooling uses natural gas to produce heat, which makes this option very efficient. The unit allows you to heat the room using a gas ducted heater and cool by means of refrigerant. This system produces warm air during winter and cool refreshing air during summer, which is the perfect option for a Melbourne home!

Benefits of add-on cooling:

  • Highly efficient
  • Cost effective
  • Uses natural gas
  • Two-in-one system – offers both heating and cooling

Gas ducted heating is one of the most efficient and cost effective ways to keep your house warm. It’s also kinder on the environment than most other options on the market, so you’re not emitting as many greenhouse gases with a gas ducted heating system.

Benefits of a gas ducted heating system

  • Highly efficient & cost effective
  • Not affected by outside temperatures
  • Low maintenance
  • Add on cooling available

If you need a unit that can do both heating and cooling, but only need it for a specific room, then the wall mounted split system could be the best option for you. Being such a popular choice on the market these days, wall split system technology is continually improving, which means these units are becoming more and more efficient and cost effective to run.

Benefits of a wall mounted split system:

  • Fast to heat and cool
  • Easy to Clean
  • Low maintenance
  • High energy star rating

The ‘bigger brother’ to the wall-mounted unit, the ducted split system can heat and cool the entire house at once. Best for using in cooling mode, the ducted split system are hidden out of sight in your wall cavity and deliver heated or cooled air via concealed ducts placed around the home.

Ducted systems can be installed in a new home or tailored to suit an existing one. Once installed, these systems are very discreet.
Benefits of ducted systems:

  • Whole home heating & cooling
  • Very quiet system
  • Visually less intrusive
  • Zoned distribution
