My wife and I built a new house after losing everything in the Seaton Bush fires some years ago, and as we intended to use ducted air-conditioning in the new house as our only source of heating and cooling, I was concerned about the running cost in light of escalation power prices.
After much research on the internet I settled on a geothermal style of heating as the most efficient and cost-effective form of air conditioning, and as a result found AusGeothermal.
I was happy that they were firstly Australian, and secondly local, so I was easily able to discuss the various aspects of my needs with them and they were very helpful and accommodating coming up with a design that fitted my needs.
I have had a great response to any of my queries from AusGeothermal, and have always recommended to anyone I talk to about air conditioning that this is the most economical type of system to run and to talk to AusGeothermal. They are almost always pleasantly surprised that they are local and not some multinational.
So, I have no hesitation in recommending AusGeothermal as a great local company with a great products and experience providing great service.
