Key Features

Extremely cost-effective

Geothermal energy is affordable and can cut electricity consumption by up to 30% in comparison to a traditional ducted system.


Geothermal systems have a relatively low level of moving parts, meaning there are less pieces that will need to be replaced due to wear and tear.

Quiet Operation

Geothermal systems are very smooth and quiet in operation, relying on the temperature of the ground to deliver heating and cooling. This results in very quiet operation.

Flexible Design

Geothermal systems can be installed in either new or retrofit applications, taking up a lot less space than traditional HVAC systems.

Works in any climate

This highly efficient direct exchange geothermal system uses constant temperatures from the ground to transfer warm or cold air into all homes, buildings and offices.


Because the stable temperature of the earth is used, heating and cooling consumption and running costs are decreased, regardless of the weather.

A Quiet Achiever

The unit is compact and slotted well into the space vacated by the previous unit. What impresses us most is its quietness and easy controls. The swing feature is most effective in getting cool air to all parts of our living area. We like the LED temperature display on the inside unit.

Great Price

Bought this in a hurry and found this as this is the most affordable from the all options. Sleek looking. When I tried it, reasonably quiet. only found later it has efficient use of electricity which is a bonus.
