Some of the systems we specialise in:

Ducted heating

Air is drawn from inside the house, heated and then dispersed into rooms via ducts. Ducted heating uses a sealed system, which means air is taken from inside the house and recycled. The heating unit is generally hidden away insdie a wall cavity or out of site of the roof.

Wall split systems

Suitable for both heating and cooling, the wall split system is best suited for single rooms where the temperature needs to be controlled. Easy to use and operate, the wall split system is a popular choice in modern homes.

Ducted Split system

Similar to the wall split system, the ducted split system pumps heated air into each room through hidden ducts. This high quality system offers the highest in efficiency and performance.

Evaporative Cooling

This is the cheapest cooling option we offer without compromising on efficiency. The costs of running evaporative cooling systems are low which allows you to enjoy a comfortable environment on the hottest of summer days while still keeping costs down.

Add–On Cooling

This unit is normally used to heat rooms using a gas ducted heater. With the add-on components you can also use the unit to cool rooms which enables you to use this unit for both heating and cooling throughout the whole year, and eliminating the need to install both heating and cooling units.
