Split System Air Conditioning

One of the more popular choices on the market, the split system is best suited for use within a single room in your home. Split systems are quiet and effective, and with the technology continually evolving, split systems are becoming more and more efficient to run. These units can also be used for heating your home in the cooler months.


Gas Ducted Add-On Cooling

As the name suggests, this unit is an add on to your existing gas ducted heating system. It allows you to cool rooms throughout your house with the addition of an add-on coil to cool air passing through the system. Gas ducted add-on cooling gives you efficient warm air during winter and cool refreshing air during summer – a perfect two-in-one system!


Ducted Split Systems

Considered the bigger brother to the wall-mounted split system, a ducted split system enables you to cool all rooms in your home simultaneously by circulating cool air through concealed ducts placed throughout the house.

Ducted split systems are very quiet, highly efficient and allow central temperature and zone control for ease of use.


Evaporative Cooling

If you’re on a budget but need a high-quality, reliable cooling system then evaporative cooling might be the ideal solution. Evaporative cooling keeps running costs low and has low greenhouse emissions. These systems are also quiet to run, and won’t dry out your skin, nose and eyes unlike other options on the market.



Gas Ducted Heating

Gas ducted heating is one of the most cost efficient ways to warm your house in those chilly winter months. With energy prices always rising, ducted gas heating has the edge on reverse cycle when it comes to both efficiency and performance. Cost effective, low maintenance and not affected by outside temperature – you can’t go wrong with a gas ducted heating system to keep your a home comfortable and consistent temperature.


Ducted Split Systems

Similar to the wall split system, but the indoor unit is out of view, hidden in your roof cavity, while the outdoor unit is located outside. Concealed ducts distribute heat throughout the house to keep you warm and the temperature consistent. This is the most high-value heating system we install.
