Highlands GeoExchange, Geothermal Energy, how it works

Unlimited and renewable geothermal energy is stored in your backyard. By using state-of-the-art technology we can harness this energy to heat and cool your home. In Winter, the heat pump extracts the heat from the ground and moves it throughout the home. In Summer, the heat from the home is expelled back into the ground.


superior comfort

One of the most valuable features of a geothermal system is the luxurious level of comfort achieved.


Geothermal systems are the most environmentally-friendly heating and cooling solutions in the world.

energy savings

A geothermal system uses up to four times less energy than a conventional system to heat or cool the same area of a home.

quiet operation

The heat pumps and insulation we use keep noise levels to a minimum.

low maintenance

Our heat pumps last longer as they have fewer mechanical components and are easier to service.

safe and reliable
