Split System Air Conditioning - Dias AIr

Wall split systems for cooling

If you need a unit for cooling a specific room in the house, such as a bedroom or living room, then a split system air conditioner may just be the option for you. These wall mounted units are becoming more and more efficient with advances in technology, and are very effective and easy to operate.

Ducted Split System

Ducted split systems for cooling

Ducted systems are considered as the ‘bigger-brother’ to the wall mounted unit – more powerful and versatile they can cool all rooms within the house at once through strategically placed ducts in every room. Requiring more investment upfront, these systems are a fantastic choice and are highly efficient – you won’t regret your decision!

Add On Cooling from Dias Air

Add-on cooling

As the name suggests, add-on cooling is the addition of a cooling unit to your gas heating system, which means you can have the convenience of both heating and cooling with one unit instead of having to invest in an additional cooling appliance.


We also specialise in heating systems to keep you and your family warm in the cooler months – as we all know Melbourne can get a bit chilly!
