Everything You Need To Know About Geothermal Cooling

Geothermal cooling is a type of cooling system that harnesses the earth’s constant underground temperature to provide a source of cool air for indoor spaces. This type of cooling system is becoming increasingly popular in the Indianapolis, IN area as a more environmentally friendly alternative to traditional air conditioning systems.

How Does Geothermal Cooling Work?

These systems use the earth as a heat sink, absorbing heat from indoor spaces and transferring it to the ground, where it is dissipated. In the summer, the system works by using a heat exchanger to extract warm air from the indoor space and transfer it to a fluid, such as water, which circulates through underground pipes. The cool earth then cools the fluid, which is then recirculated back into the indoor space to cool the air.

The system can also be used in reverse during the winter months to provide heating for the indoor space, providing a year-round solution for temperature control.


One of the main advantages is its energy efficiency. Traditional air conditioning systems rely on electricity to cool air, which can be more expensive. Geothermal cooling systems use only a fraction of the energy of traditional air conditioning, making them more cost-effective and eco-friendly.

Another advantage is its longevity. The underground piping used in geothermal cooling systems has a lifespan of up to 50 years, which is significantly longer than the lifespan of traditional air conditioning units. This means that geothermal cooling systems require less maintenance and replacement, making them a more sustainable choice in the long run.

Geothermal cooling systems are also very quiet compared to traditional air conditioning units. Much of the equipment is located underground, meaning that there is minimal noise pollution from the system.


While there are many advantages, there are also some potential drawbacks to consider. One of the main disadvantages is the high installation costs, which can be a serious obstacle for some homeowners.

Another potential downside is that they require a large amount of space for the underground piping. This can be a challenge in urban areas where space is limited, making geothermal cooling less practical for some locations.


Geothermal cooling is an environmentally friendly and energy-efficient way to control indoor temperatures. While it may be more expensive on the front end and require more space than traditional air conditioning units, it offers a long lifespan and cost savings in the long run. For those looking for a sustainable and long-lasting cooling solution, geothermal cooling is a viable option.
