geothermal hvacEnsuring that the home’s temperature is “right” is an all-time top priority for many people. There are many ways of doing so. However, our focus today is on an amazing, eco-friendly means known as geothermal energy. Geothermal energy is simply heat that comes from the underground. Through it, homeowners can not only warm their houses but also cool them.

For clarity, read through as we break down every key aspect of cooling and heating your home using geothermal energy.


How is geothermal energy used in homes?

To use this form of energy at home, a certified technician needs to install a geothermal HVAC system. This is a simple heating, cooling, and ventilating unit with a series of pipes, a geothermal heat pump, and a heat exchange fluid.

So what exactly do these components do?

A geothermal heat pump is the most important part of this system. It is divided into three subsystems: an earth connection, a heat pump, and a distributor. The earth connection subsystem has pipes (loops) that are buried underground. Depending on the conditions, the loop can be buried vertically or horizontally.

Pointer: Vertical loops are good when you have a limited working area.

Once this is done, the pipe is filled with water and an antifreeze compound. This acts as a heat exchange medium that absorbs heat from the soil in winter. The water then flows through a heat pump. A heat pump is simply a highly efficient component that concentrates heat from the water.

Lastly, the now warm water leaves the pump, entering the distribution system. This is a series of loops that crisscross the walls of a home. The system then releases heat into the surrounding environment, thereby warming the interiors.

During summer, the unit works vice versa as the process begins in the distribution system. Instead of releasing heat, the unit absorbs it from the house. The liquid then flows back to the heat pump and to the earth connection system. The latter then releases heat into the surrounding soil. So, what comes out of the earth connection subsystem is cool water. The water then flows into the house to cool it by absorbing heat to complete the cycle.


Why should we use geothermal energy?

There are a plethora of grounds for using geothermal energy for heating and cooling. First, this form of energy is available everywhere. As such, it is easy to tap and convert into usable forms in place of electric HVAC units.

That is not all, below are more reasons we should use geothermal energy.

  • It is available all year round

Compared to wind and solar energy, geothermal energy is always available. This is because the earth is a massive energy reservoir that maintains a constant temperature all year round. With this, you are guaranteed stable indoor temperatures.

  • No fuel is required to run a geothermal system  

A geothermal system doesn’t need fossil fuel to operate. It runs on natural heat extracted from the ground, which is cheap and renewable.


Why is geothermal energy important?

Below are some reasons why geothermal energy is essential;

  • It is eco-friendly
  • It reduces a home’s overall energy needs by more than 30%.
  • The geothermal heat pump requires less maintenance. Thus, it is cheap to run.
  • It is a renewable source of energy
  • The geothermal industry, as a whole, creates a record number of jobs.


How effective is geothermal energy?

The USA is among the numerous countries that are currently using geothermal energy. Across the nation, this industry services over 1 million homes. Looking at such figures, it is clear that it gets the job done and is highly effective.

Geothermal energy is not only effective but also very efficient. This is so especially when it comes to stabilizing the temperature of a house. This is all thanks to its pumps, which operate at an efficacy rate of almost 600%. This is a big deal in an industry where most HVACs’ efficacy ratings are around 40%


Can you run a house on geothermal energy?

Yes. It is possible to run your house on geothermal energy. Just find a qualified geothermal technician to set up the unit, and you are good to go.


Is residential geothermal worth it?

Definitely yes! Though an HVAC system may cost a considerable amount of money to install, it is truly a wise investment. This is because it will, without a doubt, take care of all your residential home’s heating and cooling needs.

Another amazing thing about geothermal energy is that it guarantees you as an owner tax credit. In essence, installing a geothermal HVAC system makes you eligible for a 26% federal tax credit on the unit.

Of course, we cannot forget that these systems last two times more than air-source units. Therefore, expect the system to serve you for 20-25 years. To put it into perspective, this is way longer than the lifespan of many other systems.


Is geothermal heat good for a house?

Geothermal heat is great for a house. It is a clean source of energy, and it doesn’t produce harmful smoke fumes like furnaces. This reduces the likelihood of contracting respiratory diseases.

Besides, the fact that geothermal energy is reliable is another reason why it is good for your home. With such a system, you can warm and cool your house at any time or day.

Homeowners also enjoy the system’s silent operation modes. With this, home comfort standards are taken to a whole other level.


Can you cool your house with geothermal?

One of the uses of this form of energy is to cool your home. It achieves that by absorbing heat from the house and dumping it underground. So, to answer the question, yes. One can cool their home with geothermal energy.



Geothermal is one of the most efficient and reliable sources of energy. In residential settings, it is widely used as a key heating and cooling mechanism. Apart from its efficacy and reliability, geothermal energy also has numerous other benefits. Eco-friendliness and effectiveness are a few examples of its advantages.
