GeoExchange Australia Pty Ltd (GXA) is an Australian owned company that specialises in the design, supply and installation of geoexchange (also referred to as geothermal or ground source heat pump) heating and cooling systems. We work in both the residential and commercial sectors across Australia and New Zealand as well as select projects in Asia.
Following 12 months of extensive industry research, GXA was founded in January 2006 by our current Managing Director, Yale Carden. GXA has resurrected the local industry which was lying dormant since ~2000 after the 1998 acquisition of the former WFA (founded in 1992) by Origin Energy. A number of former WFA personnel and contractors now work with GXA, providing unrivaled experience and expertise in the local industry.

MANAGEMENT OF GEOEXCHANGE INSTALLATIONS
In addition to the individual elements of a geoexchange system, our broad range of expertise enables us to ensure that your geoexchange system is a completely integrated system and not just a collection of individual parts. It is this integration that provides the incredible efficiencies for which geoexchange systems have become so well known.
Our Quality Management System has been developed in accordance with Standards produced by the International Ground Source Heat Pump Association (IGSHPA) to ensure the highest quality installations and peace of mind.
GROUND HEAT EXCHANGER CONTRACTING
The GXA contracting team have been installing ground and water loops for over twenty years and have experience with projects ranging from single boreholes to hundreds of boreholes and complex water loops.
As well as our specialist design and project management capabilities, we work with IGSHPA certified drilling contractors around the country. All systems are installed in accordance with our in-house QA system that has developed over more than 20 years, hundreds of projects and thousands of boreholes.
SERVICE AND MAINTENANCE
While geoexchange systems are legendary for their reduced service and maintenance requirements, it is important to know that qualified and experienced personnel are readily available.
WaterFurnace certified service personnel are recognised across North America as the leading industry professionals and in Australia it is no different. In Australia, we call our expert teams the Geoexchange Accredited Installers Network (GAIN) and they have been certified by both the International Ground Source Heat Pump Association (IGSHPA) and WaterFurnace.
We hold an extensive range of genuine WaterFurnace spare parts and accessories in our Adelaide warehouse for those rare emergencies.
Ensure that your system is being serviced by a WaterFurnace certified professional using genuine WaterFurnace parts.
