The Future in Heating and Cooling

What is GeoAir?

GeoAir is our flagship geothermal heating and cooling system. Commonly referred to as a Ground Source Heat Pump, geothermal systems rely on the constant
temperatures of the ground that are typically equal to average ambient temperatures.

Conventional cooling and heating systems rely on air temperatures for heat transfer that vary on a daily basis whereas ground temperatures are a constant. Constant heat transfer provides both greater efficiencies and reliability in performance.

Cooling Mode

A geothermal system circulates a
refrigerant vapour into the earth
to absorb the heat in the naturally
cooler, and stable, sub surface
temperatures. With excess heat
removed, the cooled refrigerant
condenses into a liquid. This liquid
expands through an expansion
device, lowers the pressure, and
causes the temperature to reduce
even further.

Refrigerant is then circulated through
the fan coil unit cooling your home,
building or office, and absorbing the
excessive heat from the interior air. This
causes the refrigerant to expand back
into a vapour. The cycle repeats.

Due to these much lower condensing
temperatures, the heat pump
achieves both an uplift in capacity
as well as a reduction in energy
consumption. This combination
delivers excellent system efficiencies.

Heating Mode

When operating in heating mode,
cold refrigerant is circulated within
the geothermal loop. This absorbs the
heat naturally supplied by the earth.

This heated refrigerant vapour is
compressed, and circulated through
the fan coil unit, heating the space.
This removes the heat from the
refrigerant, cooling it again.

The cycle repeats.

Save Energy

Air Conditioning can account for over 50% of a building’s energy use.  A high efficiency GeoAir system will offer significant energy cost reductions over the life of the installed plant. Typical cost recovery on an installed GeoAir system provides a sound return on investment, well within most commercial requirements.


GeoAir’s high-quality geothermal loops will outlast building ownership. There is no maintenance to perform on installed loops. The GeoAir heat pumps are Australian designed and manufactured and all mechanical equipment is easily serviceable.


Using the constant temperature of the earth, a GeoAir system is a genuine sustainable solution.  With significantly reduced energy consumption, a GeoAir system will reduce the carbon footprint of the air conditioning plant.

Quiet and Compact

Operating at a low 51dB, the GeoAir system overcomes noise issues associated with conventional mechanical plant. Through an integrated design process, GeoAir heat pumps can be concealed within building fabric. All GeoAir heat pumps are compact in design and require no ventilation providing broad options for design locations.
